Layers of Earth
The layer of hot, solid material between Earth's crust and core.
mantle
A mountain that forms when magma reaches the surface.
Volcano
The build-up of land by the settlement of
sediment and soil in a new location.
deposition
Layers of rock formed when sediment is deposited and then compacted and cemented over time.
sedimentary rock
Energy that comes directly from the sun.
solar energy
Brittle rock (cracks easily) that makes up Earth's outermost layer; where landforms and underwater features are found.
crust
Instrument used to detect and measure earthquakes.
Seismograph
A landform made of sediment that is deposited where a river flows into an ocean or lake
delta
Earth's outermost and thinnest layer.
crust
Energy that comes from changing the power of moving air into a useful form.
wind energy
A sphere of solid iron and nickel at the center of Earth
inner core
The force people feel when two plates jerk into a new position
earthquake
The destructive process which moves materials away from their place (due to gravity, water and wind).
erosion
A usually light colored igneous rock that is found in continental crust
granite
Energy that comes from the natural heat inside the Earth.
A shell of hot, liquid metal beneath the mantle and above the inner core
outer core
The place where two plates come together.
convergent boundary
The breaking down of rock into smaller pieces by forces.
mechanical weathering
Bowl-shaped indents or cavities on the
surface of a planet, moon, or asteroid
that are caused by a collision with
another object, such as a meteorite
craters
A renewable source of energy based on the natural movement of water.
Hydroelectric energy
The inner core of earth is made up of these two metals
iron and nickel
vibration that travels through Earth caused by an earthquake
Seismic wave
This is how farmers can prevent wind erosion of topsoil
surrounding fields with natural barriers (such as trees)
a hard sedimentary rock, composed mainly of calcium carbonate or dolomite, used as building material and in the making of cement.
limestone
Materials from Earth that cannot be
replaced within a reasonable amount of
time, such as oil, coal, and natural gas
Non renewable energy
