Weathering & Erosion
100

Condensation and transpiration are two processes in this cycle.

What is the water cycle?

100

The texture of this type of rock is altered as it forms.

What is metamorphic rock?

100

Scientists believe tectonic plates move because of these currents in Earth's mantle.

What are convection currents?
100

This huge wave is caused as a result of an earthquake underwater.

What is a tsunami?

100

This process is responsible for formation of sediment.

What is weathering?

200
This is the largest of the earth systems.

What is the geosphere?

200
When magma or lava cools and hardens, this type of rock is formed.

What is igneous rock?

200

Deep ocean trenches form at this type of plate boundary.

What is a convergent plate boundary?

200

This is the term for magma that erupts out of the ground.

What is lava?

200

This process moves sediment, via water, ice, or wind.

What is erosion?

300

Photosynthesis and cellular respiration are two processes in this cycle.

What is the carbon cycle?

300

The chemical composition of rock is altered under extreme temperature and pressure to form this type of rock.

What is metamorphic rock?

300

Mid-ocean ridges form at this type of plate boundary.

What is a divergent plate boundary?

300

This is the feature observed above a transform boundary, along which earthquakes often occur.

What is a fault?

300

This process breaks down rocks by changing their composition. For example, acid rain dissolves limestone.

What is chemical weathering?

400
This natural cycle does not take place in the atmosphere.

What is the phosphorus cycle?

400

This part of Earth's geosphere is liquid, and responsible for Earth's magnetic field.

What is the outer core?

400

This type of force is mostly observed at transform plate boundaries.

What is shear?

400

This phenomenon causes sediment to behave less like a solid, and is responsible for landslides.

What is liquefaction?

400

Tree root intrusion is a primary example of this process.

What is physical weathering?

500
They absorb and re-radiate thermal energy from the Sun in Earth's atmosphere.

What are greenhouse gases?

500

This type of rock forms as small pieces of other rocks pile up in one area.

What is sedimentary rock?
500

Rift lakes are evidence for what type of force, exerted at divergent plate boundaries?

What is tension?

500

This solid, outer layer of the geosphere includes Earth's crust and upper mantle.

What is the lithosphere?

500

When a glacier eventually melts, it leaves behind this large pile of sediment. Long Island is one.

What is a moraine?
