# How Does The Distribution Of Earthquakes Support The Theory

Contents

## What is the theory that explains the global distribution of earthquakes?

Plate tectonics is the theory that explains the global distribution of geological phenomena. Principally it refers to the movement and interaction of the earth’s lithosphere.

## Can you explain the distribution of earthquakes?

Earthquakes. Distribution: Most earthquake zones are found at or close to tectonic plate boundaries often in clusters. About 70% of all earthquakes are found in the ‘Ring of Fire’ in the Pacific Ocean. The most powerful earthquakes are associated with convergent or conservative boundaries.

## Why did distribution of earthquakes and volcanoes help confirm plate tectonic theory *?

Why did the distribution of earthquakes and volcanoes help confirm plate tectonic theory? Both earthquakes and volcanoes were distributed randomly. Earthquakes and volcanoes were different along different types of boundaries. Earthquakes and volcanoes were the same along all of the plate boundaries.

## How do you describe the distribution of earthquake epicenter on the world?

Answer: The earthquakes are mainly distributed along the edges of the platonic plates on the map. Explanation: The colored lines show the plate boundaries that may may past each other leading to an earthquake.

## How does the theory of plate tectonics help explain the locations of earthquakes?

Earthquakes occur along fault lines cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting spreading slipping or colliding. As the plates grind together they get stuck and pressure builds up. Finally the pressure between the plates is so great that they break loose.

## What is one reason for the distribution of earthquakes?

An earthquake is the shaking and vibration of the Earth’s crust due to movement of the Earth’s plates (plate tectonics ). Most earthquakes will happen along any type of plate boundary . Big earthquakes usually only occur at these plate boundaries.

## How are the locations of earthquakes distributed around the world?

Earthquakes are not randomly distributed around the earth rather they are located in distinct zones which can be related to the margins of tectonic plates on the Earth’s surface. Figure 6 shows the distribution of areas of most frequent earthquake activity. The active plate boundaries are superimposed on this map.

## How would you describe the distribution of earthquakes and volcanoes?

Earthquakes are commonly found in thin narrow belts associated with a plate boundary. Most volcanoes are distributed along the plate boundary. An example of a highly active earthquake zone is the west coast of North America and South America Occasionally volcanoes are found in the middle of plates (e.g. Hawaii).

## Where do earthquakes commonly occur?

The Earth’s crust (the outer layer of the planet) is made up of several pieces called tectonic plates and most earthquakes occur along their edges. The plates under the oceans are called oceanic plates. Plates that are not under the ocean are continental plates.

## Why is plate tectonics a unifying theory in geology?

Plate tectonics is considered a “unifying theory” in the field of geology because it synthesizes the work and theories of most other areas of geology (Oreskes and LeGrand 2003). … Plate tectonic theory even unites the ideas of sea-floor spreading subduction and mantle convection.

## Why do earthquakes volcanic eruptions and mountain ranges do not occur randomly on Earth?

Volcanoes and earthquakes are not randomly distributed around the globe. Instead they tend to occur along limited zones or belts. … As the plates move their boundaries collide spread apart or slide past one another resulting in geological processes such as earthquakes volcanoes and mountain making.

## How will you relate the distribution of mountain ranges with the distribution of earthquake?

Most mountain ranges are built along plate boundaries where the plates are crashing together. … Earthquakes in this situation are highly correlated with mountain ranges but they are not correlated with the growth of a specific mountain. You would not expect volcanoes in this type of continental collision.

## How will you describe and relate the distribution of major mountain belts to plate tectonic theory?

Most mountains and mountain ranges are parts of mountain belts that have formed where two lithospheric plates have converged and where in most cases they continue to converge. In effect many mountain belts mark the boundaries of lithospheric plates and these boundaries in turn intersect other such boundaries.

## How will you relate the distribution of mountain ranges with the distribution of earthquake zones?

Answer: Areas where there are mountain ranges are most likely to have earthquakes despite it being the reason why mountain ranges are formed and where active volcanoes there are also earthquakes occurring.

## How does the theory of plate tectonics explain the location of earthquakes and volcanoes Where do most earthquakes and volcanoes occur?

The features seen at a plate boundary are determined by the direction of plate motion and by the type of crust found at the boundary. Most geological activity takes place at plate boundaries. It explains why volcanoes earthquakes mountain ranges ore deposits and other features are located.

## How does plate tectonic theory help explain the formation of volcanoes and the cause of their eruptions?

As the denser plate edge moves downward the pressure and temperature surrounding it increases which causes changes to the plate that melt the mantle above and the melted rock rises through the plate sometimes reaching its surface as part of a volcano.

## How does the theory of plate tectonics explain the movements of tectonic plates?

The theory of plate tectonics states that the Earth’s solid outer crust the lithosphere is separated into plates that move over the asthenosphere the molten upper portion of the mantle. Oceanic and continental plates come together spread apart and interact at boundaries all over the planet.

## Why is it important to be aware of places prone to earthquakes?

It is important to know your risks. The chances of an earthquake occurring is different from place to place depending on the location and proximity to active fault lines and plates. Areas such as the “Pacific Rim” are prone to earthquake activity so different precautions must be taken in these high risk areas.

## Where do earthquakes occur ks3?

Earthquakes can happen along any type of plate boundary. Earthquakes occur when tension is released from inside the crust. Plates do not always move smoothly alongside each other and sometimes get stuck.

The earthquakes are mainly distributed along the edges of the platonic plates on the map. Explanation: The colored lines show the plate boundaries that may may past each other leading to an earthquake. The map also differentiates the different movements of the plates like rubbing against each other or moving apart.

## How does the distribution of earthquakes and volcanoes related to movement at plate boundaries?

When an oceanic and continental crust move towards each other a destructive plate boundary is formed. A collision plate margin is formed where two continental plates move together. … Conservative boundaries form where two plates slide past each other. Volcanoes and earthquakes do not occur just anywhere.

## What causes earthquakes and where do they happen?

An earthquake is caused by a sudden slip on a fault. … When the stress on the edge overcomes the friction there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel. In California there are two plates – the Pacific Plate and the North American Plate.

## Is there a direct relationship between where earthquakes occur and where plate boundaries are located?

Most earthquakes occur at the boundaries where the plates meet. In fact the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. There are three types of plate boundaries: spreading zones transform faults and subduction zones.

## Does the location of earthquakes and volcanoes show a pattern?

The locations of earthquakes and volcanoes on Earth do show a pattern. The pattern is that earthquakes and volcanoes are arranged along tectonic plate

## What is the most important evidence that supports the plate tectonics theory?

Evidence from fossils glaciers and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. Some life “rode” on diverging plates became isolated and evolved into new species.

## What evidence is there to support the plate tectonics theory?

There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents (2) the occurrence of earthquakes and (3) continental and ocean floor features including mountains volcanoes faults and trenches.

## Why is plate tectonic theory the overlying theory of geology?

Plate tectonics is the unifying theory of geology the framework into which are fitted all other explanations of large-scale geological phenomena such as earthquakes volcanoes and the existence of ocean basins and continents. … Some of these moving plates bear the continents while others underlie the ocean basins.

## How are earthquakes volcanoes and mountains distributed on the map?

The epicenters of volcanoes mountain ranges and earthquakes are not spread randomly on the map. They are in a region where the plate boundaries may be found. They aren’t ‘distributed’ in the traditional sense. Mountain ranges form when plates clash or when volcanic fault lines run across them.

## How are earthquakes volcanoes and mountain belts distributed?

Looking at the positions of most if not all volcanoes earthquakes and major mountain belts they are distributed mainly around the tectonic plate boundaries. … The distribution of the volcanoes earthquake epicenters and major mountain belts are distributed in close proximity of the borders of the tectonic plates.

## How are volcanoes and mountain ranges distributed?

Volcanoes are not randomly distributed over the Earth’s surface. Most are concentrated on the edges of continents along island chains or beneath the sea forming long mountain ranges. … Major tectonic plates of the Earth. Only a few of the Earth’s active volcanoes are shown.

## How do you describe the locations of earthquake epicenters mountain ranges and moving plates in the Pacific Ring of Fire?

The abundance of volcanoes andearthquakes along the Ring of Fire is caused by the amount of movement of tectonic plates in the area. Along much of the Ring of Fire plates overlap at convergent boundaries called subduction zones. That is the plate that is underneath is pushed down or subducted by the plate above.

## What is your conclusion regarding the location of volcanoes earthquake and mountain ranges?

Volcanoes earthquakes and mountain ranges can all be found at the site of convergent boundaries. Finally earthquakes are also found at the site of transform boundaries. Each of our learning activities was a line of evidence.

## What is the relationship among the locations of volcanoes earthquake epicenters and mountain ranges?

Answer. when the earthquake occurs the epicenter of the earthquake will develop mountain ranges Mountains Or the soil may go down the and become magma The magma melts and become a Lava which has been erupted by the volcano when the magma melts and the Volcano will erupt when the earth reaches its maximum temperature.

## How are mountain belts distributed in the Philippines?

The distribution of Philippine Pliocene-Quaternary volcanoes generally reflects the activity along subduction zones presently bounding the archipelago. Five distinct volcanic belts van be defined namely: … East-Philippine Volcanic Arc associated with the Philippine Trench. Negros-Panay Arc linked to the Negros Trench.
