Earth Science

A convergent boundary is where two tectonic plates push against each other, often causing mountains to form or earthquakes to occur.

Erosion is the process that moves broken pieces of rock and soil from one place to another, often by wind, water, or ice.

A divergent boundary is where two tectonic plates move apart from each other, often creating new crust as magma rises to the surface.

Faults are cracks in the Earth's crust where blocks of rock have moved, often causing earthquakes.

A levee is a raised bank of Earth or a wall built along the edge of a river to prevent flooding.

A transform boundary is where two tectonic plates slide past each other horizontally, which can cause earthquakes.

Sediment is small pieces of rock, soil, and organic material that are moved by erosion and can accumulate in layers.

The rock cycle is the continuous process of rock formation, breakdown, and reformation through processes like erosion, melting, and cooling.

A dam is a structure built across a river to hold back water, creating a reservoir for water supply, flood control, or hydroelectric power.

Weathering is the process that breaks down rocks into smaller pieces through physical or chemical means.
