Lesson 2 - Earth's Water Cycle: Flashcards
What is the Cryosphere?
The cryosphere is water in solid form on the Earth’s surface.
What is the Lithosphere?
The lithosphere is water in liquid form on the Earth’s surface.
What is the Hydrosphere?
The hydrosphere is all the Earth’s water.
What is the Atmosphere?
The atmosphere is water in gaseous form in the Earth’s atmosphere.
What are Ice Sheets?
Ice sheets are masses of glacial ice more than 50,000 square kilometres.
What are Ice Shelves?
Ice shelves are floating sheets of ice permanently attached to a land mass.
What is Sea Ice?
Sea ice rises when seawater freezes because ice is less dense than water.
What is Permafrost?
Permafrost is an area of land permanently frozen.
What are Alpine Mountain Glaciers?
Alpine mountain glaciers are confined by surrounding mountainous terrain.
What are Aquifers?
Aquifers are an underground layer of water-bearing permeable rock.
What are Fossil Aquifers?
Fossil aquifers are large underground reserves of water that were established under past climatic and geological conditions, and are no longer replenished.
What is the Process of Sublimation?
Sublimation is the transition of a solid directly into a gas state, without changing to a liquid first.
What factors drive change in the Water Cycle?
1) Amount of water present in each store,
2) Magnitude of each store, depends on the amount of water flowing between them.
What are the Water Cycle’s Main Transfers?
1) Evaporation,
2) Evapotranspiration,
3) Condensation,
4) Precipitation,
5) Cryospheric Processes.
