Earth's Dynamic Features Quiz

Weathering involves the breakdown of rocks into smaller particles by physical, chemical, and biological processes.

Shield volcanoes have gentle slopes due to the low viscosity of basaltic lava.

Deposition occurs when glaciers melt, depositing sediment they have transported, often shaping landscapes.

A crater is the bowl-shaped depression at the top of a volcano, typically formed during eruptions.

Earthquakes occur due to the sudden release of stress accumulated along faults in the Earth's crust, generating seismic waves.

Solidification occurs as molten rock material cools and crystallizes to form igneous rocks.

Heat generated by radioactive decay in Earth's interior drives convection currents, contributing to plate movement.

There are three primary types of plate boundaries: divergent, convergent, and transform.

Pangaea was the ancient supercontinent that later split into the continents we recognize today.

Seismic waves include P-waves (primary), S-waves (secondary), and surface waves, but there is no T-wave.

Wind speed is not typically considered a direct factor affecting the rate of weathering, unlike factors such as temperature, moisture, and rock type.

The Mohorovičić discontinuity (Moho) marks the boundary between the Earth's crust and the mantle.

Seafloor spreading occurs as tectonic plates move apart, allowing magma to rise and solidify, forming new crust.

Unconformities represent gaps in the geologic record due to erosion or non-deposition.

Tornadoes are not geological features; volcanoes can be classified as shield, composite, or cinder cone, but not 'tornado' volcano.

Faults are fractures where movement has occurred; common types include normal, reverse, and strike-slip, but not 'convective' fault.

Rocks deform under stress, such as compression, tension, and shear, but not 'expansion' stress.
