2nd 9 Weeks PMA Review

Front

What are hot spot volcanoes?

Back

Hot spot volcanoes are a progression of volcanoes that form when mantle plumes periodically erupt through the surface of moving tectonic plates.

Front

What processes lead to the formation of sedimentary rocks?

Back

Sedimentary rocks form through the processes of compaction and cementation of sediments.

Front

What is reflection in terms of light?

Back

Reflection is the bouncing of light off a surface at identical angles.

Front

Describe the formation of igneous, sedimentary, and metamorphic rocks.

Back

Igneous rocks form from cooling magma, sedimentary rocks form from compaction, and metamorphic rocks form from heat and pressure.

Front

What do unbalanced forces change in moving objects?

Back

Unbalanced forces change the speed or direction of moving objects, which together are called velocity.

Front

Define compaction in geology.

Back

Compaction is the process by which sediments are pressed together under pressure, leading to the formation of sedimentary rocks.

Front

What is cementation in the rock cycle?

Back

Cementation is the process where dissolved minerals crystallize and glue particles of sediment together, forming sedimentary rocks.

Front

What is the difference between speed and velocity?

Back

Speed is the rate at which an object moves, while velocity includes both speed and direction.

Front

What is the role of heat and pressure in the formation of metamorphic rocks?

Back

Heat and pressure cause existing rocks to change into metamorphic rocks through processes like recrystallization.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, involving igneous, sedimentary, and metamorphic rocks.
