How do geologists use earthquakes to obtain information about Earth’s interior?
One ingenious way scientists learn about Earth’s interior is by looking at earthquake waves. Seismic waves travel outward in all directions from where the ground breaks and are picked up by seismographs around the world. Two types of seismic waves are most useful for learning about Earth’s interior.

Convection occurs in the troposphere the lowest region of Earth’s atmosphere. It is the cause of surface winds and weather. … By making it more difficult for Earth to radiate its energy back into space the greenhouse effect makes our planet’s surface some 40 K warmer than would otherwise be the case.

What natural phenomena on Earth provide information on the structure of Earth’s core quizlet?
What natural phenomenon on Earth provides information on the structure of Earth’s core? The seismic waves produced by earthquakes provide information about the structure of Earth’s core.
What are formed when the Earth’s crust breaks into huge segments?
The Earth’s crust is broken into plates that are in constant motion over timescales of millions of years. … This provided a focal point where the mantle underneath the plate could rapidly melt forming magma that erupted easily through the thinned plate and onto the surface in massive outbursts of volcanic activity.
What has been the primary mechanism for the creation of the large scale features of Earth’s continents and crust quizlet?
What about Earth’s tectonic activity is true? It is most likely driven by convection within Earth’s mantle. What has been the primary mechanism for the creation of the large-scale features of Earth’s continents and crust? Part of moons.
How do geologists use earthquakes to obtain information about Earth’s interior quizlet?
How do geologists use earthquakes to obtain information about Earth’s interior? When waves from earthquakes travel through the Earth’s interior properties of those waves such as their intensity and speed are changed by the materials they pass through.
How do we get information about the interior of the Earth?
Except in the crust the interior of the Earth cannot be studied by drilling holes to take samples. Instead scientists map the interior by watching how seismic waves from earthquakes are bent reflected sped up or delayed by the various layers.
What are the source of the Earth’s internal structure?
The core is earth’s source of internal heat because it contains radioactive materials which release heat as they break down into more stable substances. The core is divided into two different zones. The outer core is a liquid because the temperatures there are adequate to melt the iron-nickel alloy.
What effect does convection have on Earth’s atmosphere quizlet?
Convection is the constant upwelling of warm air and the concurrent downward flow of cooler air to take its place a process that physically transfers heat from a lower (hotter) to a higher (cooler) level. The resulting circulation currents cause the winds in the Earth’s atmosphere as a result of solar-heated ground.
What happens when solar radiation enters Earth’s atmosphere?
How does convection in Earth’s mantle affects the formation of landmass like volcano and mountain?
When warm material in the mantle rises up to the surface (ground) it. will cool and sinks these cooled materials will eventually be turned into. landmass.
What is the meaning lithosphere?
The lithosphere is the solid outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
What do you know about the Earth structure?
How do seismic waves tell us about the Earth structure?
Knowing how the waves behave as they move through different materials enables us to learn about the layers that make up the Earth. Seismic waves tell us that the Earth’s interior consists of a series of concentric shells with a thin outer crust a mantle a liquid outer core and a solid inner core.
What causes the natural phenomenon?
What natural phenomenon occurs on Earth due to the gravity of the moon?
Gravity is one major force that creates tides. In 1687 Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich J.L. 1996).
What are some examples of natural phenomena?
Common examples of natural phenomena include lightning earthquakes tsunamis volcanic eruptions tornadoes and similar.
What is peridotite quizlet?
peridotite. A coarse-grained ultramafic intrusive igneous rock composed of olivine with small amounts of pyroxene and amphibole. The dominant rock in Earth’s mantle and the source rock of basaltic melts.
What are the two major constituents of the Earth’s atmosphere quizlet?
77% nitrogen and 21% oxygen.
What is a convection quizlet?
Define convection. It is the heat transfer in a fluid by the movement of particles in it. … The particles in a fuid (liquid or gas) are able to move about in the medium to transfer heat energy from one region to another through convection.
What is the process of Earth’s crust being created and destroyed?
Just as oceanic crust is formed at mid-ocean ridges it is destroyed in subduction zones. Subduction is the important geologic process in which a tectonic plate made of dense lithospheric material melts or falls below a plate made of less-dense lithosphere at a convergent plate boundary.
How was Earth’s crust formed?
What caused the Earth to split?
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. … Today we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.
How is the existence of Earth’s unique atmosphere explained?
How is the existence of Earth’s unique atmosphere explained? … It reaches Earth’s surface where some is reflected and some is absorbed.
What conditions are needed to create a dynamo in Earth’s interior What effect does Dynamo have?
What conditions are needed to create a dynamo in Earth’s interior? What effect does this dynamo have? Both rapid rotation and a conducting liquid core are needed. Produces a magnetic field.
What is the primary cause of the auroras northern and southern lights quizlet?
A glow in the Earth’s ionosphere caused by the interaction between the Earth’s magnetic field and charged particles from the Sun (The Solar Wind). It gives rise to the “Northern Lights” or Aurora Borealis in the Northern Hemisphere and the Aurora Australis in the Southern Hemisphere.
How do we get information about the Earth’s interior quizlet?
Geologists have used two main types of evidence to learn about Earth’s interior: direct evidence from rock samples and indirect evidence from seismic waves. … Made up of rock that is very hot but solid. Scientists divide the mantle into layers based on physical characteristics.
Which type of waves give scientists information about the structure of Earth’s interior layers quizlet?
How are seismic waves used to provide evidence about earth’s interior? Seismic waves released during earthquakes are recorded and studied. By analyzing the speed and paths taken by the waves scientists can infer what the earth’s interior is like. List Earth’s three main layers.
What are the two main ways that scientists learn about Earth’s interior and what do these two things indicate quizlet?
Geologists have used two main types of evidence to learn about Earth’s Interior: direct evidence from rock samples and indirect evidence from seismic waves. How are seismic waves used to provide evidence about earths interior?
