Flashcard Plate tec/earth materials

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various stages: igneous, sedimentary, and metamorphic, driven by geological processes such as cooling, erosion, and heat.

Front

What process occurs when magma cools and solidifies?

Back

Cooling and hardening.

Front

What are the two types of Earth's crust?

Back

Oceanic crust and continental crust.

Front

What geologic feature is formed at a divergent boundary between oceanic crust?

Back

Mid-Ocean Ridge.

Front

What is the layer of semi-solid molten rock beneath the Earth's crust called?

Back

Mantle.

Front

What is plate tectonics?

Back

Plate tectonics is the theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is a volcanic eruption?

Back

A volcanic eruption is the release of magma, gas, and ash from a volcano, often resulting in the formation of new landforms.
