Geologic Processes-2.2

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, influenced by geological processes such as weathering, erosion, and heat.

Front

What are igneous rocks?

Back

Igneous rocks are formed from the cooling and solidification of magma or lava. Examples include granite (intrusive) and basalt (extrusive).

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles. Examples include sandstone, limestone, and shale.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed from existing rocks that undergo changes due to heat, pressure, or chemically active fluids. Examples include schist and marble.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often leading to volcanic activity.

Front

What is the difference between the inner core and the mantle?

Back

The inner core is solid and primarily composed of iron and nickel, while the mantle is semi-solid and made up of silicate rocks.

Front

What causes tectonic plates to move?

Back

Tectonic plates move due to convection currents in the mantle caused by heat from the Earth's core.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move apart, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, which can result in mountain formation, earthquakes, and volcanic activity.

Front

What is a transform boundary?

Back

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