Geosphere
These make up the geosphere.
What are the rocks and minerals of planet earth.
These large bodies of water hold 97% of the water on earth at any given time.
What are the oceans?
These make up the atmosphere.
What are the layers of gas surrounding earth?
These make up the biosphere.
What are all the living things on earth?
Most living things depend on freshwater to drink but only about this much of the water on earth is available for that purpose.
What is 1% of the water on earth?
This is the process by which rocks are broken down into sediments.
What is weathering?
These are the specific terms for the three states in which water can exist in the hydrosphere.
What are ice, liquid water, and water vapor?
This the the term for moving air in the atmosphere.
What is wind?
These parts of living things can cause erosion by growing into and expanding within small cracks in rocks.
What are the roots of plants?
These are examples of landforms created by water erosion by rivers. Give two.
What are valleys, canyons, waterfalls?
These events can affect and change the geosphere by creating new igneous rock, including new landforms such as mountains and islands.
What are volcanic eruptions?
Approximately 68% of the freshwater on earth or 2% of the total water on earth is found here.
What are glaciers and ice caps?
This is the process by which clouds form in the atmosphere.
What is condensation?
These are the things that plants use to carry out photosynthesis.
What are air, water, and sunlight?
Activities such as mining, construction, road building, and tunneling are ways that these members of the biosphere can affect the geosphere.
What are humans?
These are the areas in which most earthquakes are volcanic eruptions occur.
What are tectonic plate boundaries?
These are the three main processes that move water through the hydrosphere and the atmosphere.
What are evaporation, condensation, and precipitation?
These are examples of hazardous conditions that can arise in the atmosphere. Give two.
What are high winds, thunderstorms, hail, blizzards, heavy rains, tornadoes, hurricanes?
What are decomposers?
Farmers plant cover crops, or crops that are grown to cover a field when it would otherwise be bare, in order to prevent this.
What is erosion?
This is the process by which triangular, low-lying landforms, called deltas, form at the point where a river meets the ocean.
What is deposition?
This is the type of water that is present in a body of water without an outlet.
What is saltwater?
This is the process by which landforms such as sand dunes, arches, and hoodoos are formed.
What is wind erosion?
This is the ultimate source for all the energy used by living things on earth.
What is the sun?
An earthquake in the geosphere can cause this hazardous event in the hydrosphere.
What is a tsunami?
