Unit 2 Geosphere Review

Plate Tectonics

100

Determine the three main parts of the Earth's interior

Crust, Mantle, Core

200

What differences in magma/lava control whether an eruption will be quiet or explosive?

The viscosity. Higher viscosity, louder the explosion.

300

Why do some crust plates subduct and other don't?

Oceanic plates are denser, so they subduct.

400

Give the name of the most recent supercontinent

Pangaea

500

Using arrows, show the difference between divergent, convergent, and transform plate boundaries.

Divergent: <-->

Convergent: -><-

Transform: Up Down

Landforms

100

Give 1-6 of the variables that affect the rate of weathering. For each correct answer, I will give 100 points. If any are incorrect, you get NO points.

Rock Composition

Exposure

Elevation

Topography

Organism Activity

200

Describe the difference between the epicenter and the focus.

The focus is where the movement from an earthquake is first detected in the earth, the epicenter is where the movement happens on the surface of the Earth.

300

Describe the difference between a rockslide, landslide, and creep.

Rockslide: Very quick mass movement where rocks move down a slope

Landslide: Very quick mass movement where rocks and dirt move down a slope

Creep: A sudden mass movement where rocks and dirt move down a slope in one full piece

400

Describe the difference between S, P, Love, and Rayleigh waves.

S: Body waves that move front to back

P: Body waves that move left to right

Love: Surface waves that go back and forth

Rayleigh: Surface waves that move in a rolling motion

500

Describe the difference between the intensity and the magnitude of an Earthquake

Intensity: Measures the effects of an earthquake (Mercalli Scale)

Magnitude: Measures the amount of ground movement during an earthquake (Richter Scale)

Dirt

100

Describe the difference between chemical and mechanical weathering.

Chemical weathering happens when a rock is broken down by chemical reactions

Mechanical weathering happens when rock is broken down by physical means

200

Describe the difference between erosion and weathering.

Weathering is the break down of parent material, while erosion is the movement of the sediment that was broken down.

300

Describe the difference between a soil profile, soil texture, and a soil composition

Profile: A horizontal view of a soil sample with the horizons included.

Texture: How soil feels to the touch

Composition: The amount of sand, silt, clay in a soil sample.

400

Give a quick description of the three main rock types

Igneous: Cooled magma or lava

Sedimentary: Small fragments of rock pressed together into larger rocks

Metamorphic: A rock changes form

500

Describe the three types of mechanical weathering.

Ice wedging: Water going into crack, freezing, and widening those cracks

Abrasion: Collision of rocks that wears them away

Plant/Animal Activity: Plant roots wedging into rocks and animals burrowing and abrading the rocks

Review
