Earth Science "Rocks"

The breaking down of rock at a molecular level. Changes the chemical composition of the rock.

Which soil horizon is composed of topsoil?

What characteristic is the name of a sedimentary rock based on?

Which type of rock is made when deposited materials compact and cemented together?

An extrusive rock has small/no crystals because it cools __________________.

The organic component of soil, formed by the decomposition of leaves and other plant material

Which type of igneous rocks form outside of Earth's crust at/near the surface.

Which type of metamorphic rock has repetitive layering of the minerals?

What is the process of freezing water expanding in the cracks of rock, breaking it apart.

Which type of rock is formed when dissolved minerals are left behind (precipitates) when the liquid evaporates?

In which environment does an intrusive igneous rock cools down and solidifies?

The process of rock physically being split or broken down into small pieces. Big rocks into small rocks.

What type of rock is on the right?

The break up of rock due to exposure to processes that occur at the Earth's surface.

The process by which eroded sediment materials settle out or get dropped in a location.

When does a river begin to drop large sediments?

Which soil horizon is composed of bedrock or parent material?

What causes a rock to "change" into a metamorphic rock?

Which type of metamorphic rocks have little or no mineral banding and are relatively homogenous (same composition)

Rock formed from the stratified remains of plant material or carbonate-shelled organisms (shellfish or coral)

What level of metamorphism is the Non-visible layering of fine-grained platy (flat/flaky) minerals

What causes the vesicules in this rock?

Wearing away rock material by a grinding motion by wind, water, or ice.

Composed of loose rock fragments and clay derived from weathered rock mixed organic material

Which is not a step in the process of forming a sedimentary rock?

Fragment of pre-existing rock (clast) that is broken down by processes of weathering

The process by which sediments are physically incorporated into moving water, ice, or wind.
