Earth’s Changing Surface Study Guide
Igneous Rock: a type of rock formed when cooled and hardened by magma.
Metamorphic Rock: a type of rock formed when a rock is changed by heat or pressure.
Sedimentary Rock: a type of rock formed when layers of rock pieces are cemented
together
Hardness is the measure of how easily a mineral can be scratched or indented.
Quartz, gypsum, and talc are examples of minerals.
Humus: material in the soil that comes from living things.
According to the rock cycle igneous and metamorphic rock could change by
weathering and erosion.
Fossils are found in sedimentary rocks.
Deltas are created when sediment carried down from a river is deposited past the
mouth of a river.
Evidence of glaciers are shown with scratches on horizontal rock surfaces, rock piles,
and boulder left in the middle of the fields.
Land erosion is responsible for wearing a mountain down over time.
Weathering is the process of breaking down rocks.
Earthquakes do not aid in the process of erosion.
Water erosion is responsible for most changes in landforms.
Water helps rocks break apart by freezing and expanding.
A moraine forms from a glacier melting and leaving sediment.
A volcano is a constructive and destructive process.
When glaciers move they pick up rocks, boulders, and move them this is an example of
erosion.
Deposition forms floodplains and deltas.
A delta forming is a constructive process.
Weathering can take place by water, ice, and wind.
Sand dunes and deltas are formed by constructive forces.
Deposition is a constructive process it builds Earth’s surface up, erosion is a destructive
process it takes surface areas away.
