Earth's Layers and Rocks

Sedimentary Rock

• rock formed by heat and pressure

• rock formed when lava or magma cools and hardens

• Rocks formed when sediments are cemented together

• a process that shows how rocks can change over time

Rock Cycle

• a process that shows how rocks can change over time

• the wearing down and breaking up of hard rock by natural forces like wind, water, ice, gravity, or animals

• movement of rocks and soil from one place to another by the forces of wind, water, ice, or gravity

• formed by layers of rock that have been weathered and eroded and then pressed together

Igneous Rock

• created when rock deep in Earth's crust is exposed to so much heat and pressure that it changes into something new

• rock that forms when hot magma or lava cools and hardens

• formed by layers of rock that have been weathered and eroded and then pressed together

• parts of the Earth's crust that rest on the mantle

Tectonic Plates

• rock that forms when magma or lava cools and hardens

• a place where plates slide against each other

• the upper layer of Earth, where we live.

• Parts of the Earth's crust that rest on the mantle.

Metamorphic Rock

• when sediment is transported by natural forces (wind, water, ice, gravity, or animals)

• rocks formed when lava or magma cools and hardens

• rocks formed by heat and pressure

• created when rock deep in Earth's crust is exposed to so much heat and pressure that it changes into something new

What is Weathering?

• the wearing down and breaking up of hard rock by natural forces like wind, water, ice, gravity or animals

• the movement of rocks and soil from one place to another by the forces of wind, water, ice or gravity

• when tectonic plates move away from each other

• where Earth's plates slide alongside each other

What is a divergent boundary?

• When tectonic plates slide alongside each other

• When tectonic plates move toward each other

• When tectonic plates move away from each other

• The upper layer of the Earth, where we live

What is erosion?

• When tectonic plates move away from each other

• When sediment is transported by natural forces (wind, water, ice, or gravity) and dropped somewhere else

• the movement of rocks and soil from one place to another by the forces of wind, water, ice, or gravity

• parts of the Earth's crust that rest on the mantle

What is deposition?

• the wearing down and breaking up of hard rock by natural forces

• the movement of rocks and soil from one place to another

• rock formed when layers of rock have been weathered and eroded and pressed together

• when sediment is transported by natural forces (wind, water, ice or gravity)

Convergent Boundary

• the place where tectonic plates move away from each other

• the place where tectonic plates move alongside each other

• the place where tectonic plates move towards each other

• the place where tectonic plates move diagonally apart
