| Question | Answer |
|---|---|
| most geologically active region on the surface of Earth | boundaries between tectonic plates |
| producers of oxygen | plants |
| ozone layer location | stratosphere |
| Large-scale atmospheric phenomena caused by air that is constantly in motion | weather |
What part of Earth encompasses all areas where living organisms can obtain the energy they need?
What is a large-scale atmospheric phenomena caused by air that is constantly in motion known as?
Large-scale atmospheric phenomena caused by air that is constantly in motion is known as. convection.
What does the Richter scale best describe?
the richter scale best describes the. magnitude of an earthquake.
Which of the following is earth’s densest atmospheric layer?
The troposphere is the densest atmospheric layer compressed by the weight of the rest of the atmosphere above it.
What is the region between the surface and atmosphere of the earth occupied by living organisms called?
What is the regions of the surface and atmosphere of Earth occupied by living organisms called?
What makes a region geologically active?
At their boundaries the plates spread apart converge and slide past one another. These boundaries the danger lines described in the SAVAGE EARTH program “Hell’s Crust ” are the most geologically active regions on Earth.
Why is air denser near Earth’s surface?
Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity so gas particles are denser near the surface. With more gas particles in a given volume there are more collisions of particles and therefore greater pressure. … With greater depth of the atmosphere more air is pressing down from above.
What do most land animals depend on angiosperms for?
What is an angiosperm? … Angiosperms depend on aniamsl to disperse their seeds and carry their pollen Most land animals depend on flowering plants (like the angiosperm) for food.
Is a 10.0 earthquake possible?
Is a 7.2 earthquake bad?
…
Earthquake Magnitude Scale.
| Magnitude | Earthquake Effects | Estimated Number Each Year |
|---|---|---|
| 7.0 to 7.9 | Major earthquake. Serious damage. | 10-15 |
| 8.0 or greater | Great earthquake. Can totally destroy communities near the epicenter. | One every year or two |
Is a 6.0 earthquake bad?
The larger the magnitude of the earthquake the bigger the area over which landslides may occur. In areas underlain by water-saturated sediments large earthquakes usually magnitude 6.0 or greater may cause liquefaction. The shaking causes the wet sediment to become quicksand and flow.
Is air denser near Earth’s surface?
Air is denser near Earth’s surface than high in the atmosphere. Particles of air in the atmosphere exert pressure on Earth’s surface. … As you move upward from Earth’s surface wind speeds increases because the air meets with less friction from Earth’s surface.
Which layer of the atmosphere has the greatest range in distance?
What is the most abundant gas in the atmosphere?
What is the percentage of water on the Earth’s surface is in the form of ocean?
96.5 percent
About 71 percent of the Earth’s surface is water-covered and the oceans hold about 96.5 percent of all Earth’s water.
Which is the only zone of atmosphere in which most living organisms found?
What is biosphere 9th CBSE?
Biosphere : The life-supporting zone of the Earth where the atmosphere hydrosphere and the lithosphere interact and make life possible is known as the biosphere. … Abiotic components : The non-living things air water and soil form the abiotic components of the Biosphere.
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 are the largest among the four subsystem?
These four subsystems are called “spheres.” Specifically they are the “lithosphere” (land) “hydrosphere” (water) “biosphere” (living things) and “atmosphere” (air).
Why is biosphere called the largest ecological system?
Biosphere is called the largest ecological system because it will contain all types of ecosystem and surrounded by the atmosphere to balance the life on the earth.
What is geologically active?
When we talk about “geologically active” as it relates to Earth we know what that means: mountain-building processes volcanic flows earthquakes canyon-creating processes plate motions erosion (by wind and water) and so on. These are processes that geologists study.
What is geologically active mean?
A feature is geologically active if it experiences changes from processes within the earth’s crust.
How do we know that Earth is geologically active?
Why is Earth geologically active? Internal heat drives geological activity and Earth retains plenty of internal heat because of its relatively large size for a terrestrial world. This heat causes mantle convection and keeps Earth’s lithosphere thin ensuring active surface geology.
Why is the density of the atmosphere is maximum near the Earth’s surface?
Since air density is the number of air molecules in a given space (volume) air density is typically greatest at the surface or sea level (where it is squeezed by the weight of the entire atmosphere above) and decreases as we move up in the atmosphere because the weight of air above becomes less and hence there is less …
Why is the density of atmosphere highest near the surface of the Earth?
The sun heats the surface of the Earth and some of this heat goes into warming the air near the surface. The heated air is then diffused or convected up through the atmosphere. Thus the air temperature is highest near the surface and decreases as altitude increases.
Why atmosphere is thicker and heavier near the Earth’s surface?
The closer to the Earth’s surface the greater the weight (or force) of the atmosphere because air near the surface has ALL air above it pushing down on it. As an airplane travels higher into the atmosphere air pressure decreases. The higher an airplane goes the less dense the atmosphere becomes.
What are the first organisms to colonize any newly available area called?
Such plants are called pioneer species-the first organisms to colonize any newly available area and begin the process of ecological succession.
What do most scientist classify organisms into?
Scientists use many types of information to place organisms into groups. The groups are arranged in levels. These levels are kingdom phylum class order family genus and species. Each level is more specific than the one above it.
