BCS8 Chapter 10 Flashcards
condensation
the process of changing state from a gas to a liquid
evaporation
the process of changing state from a liquid to a gas
freezing point
the temperature at which a liquid becomes a solid as heat is removed
hydrologist
a scientist who studies Earth’s water systems and helps find solutions to problems related to water quality and quantity
melting
the process of changing state from a solid to a liquid
solidification
the process of changing state from a liquid to a solid by the removal of heat
sublimation
the process of changing state from a solid to a gas without going through the liquid stage
density
the mass of a given volume
salinity
a measure of the amount of salts dissolved in a liquid
crevasse
deep crack that forms in a glacier
glaciers
deep crack that forms in a
glacier
gravity
the attractive force between objects; the force that causes objects to be pulled toward the centre of Earth
ground water
the water that has seeped into the ground from the surface of Earth
iceberg
a large chunk of ice that breaks off a glacier into the ocean
cave
a large underground hollow in rock created over time by weathering and erosion
delta
an area of built-up sediment deposited by a river where the river empties into an ocean or a lake
deposition
in geology, the process in which eroded sediments and other material are dropped or left by water or ice, creating built-up landforms such as deltas and eskers
erosion
the transport of sediments from one place to another by agents such as water, glaciers, gravity, and wind
karst
an area with many sinkholes
landslide
a sudden, rapid movement of rock material down the slope of a hill or mountain
rapids
an area of fast-moving, churning water in a steep, rocky river
striations
scratch marks cut into rock by glaciers slowly moving over it
weathering
the gradual process of breaking down rock into smaller fragments
