Rocks and Rock Cycle

You find a deposit of organic limestone. In what type of rock setting did it probably form?

• the ocean

• a volcano

• a swamp

• sand dunes

The process by which metamorphic rock changes to igneous rock begins with

• melting

• erosion

• deposition

• crystallization

You find a rock in which the grains are arranged in wavy, parallel bands of white and black crystals. What kind of rock have you probably found?

• igneous

• sedimentary

• metamorphic

• extrusive

The streak of a mineral is the

• color of the rock

• when it carved a line in a surface

• is the color of it´s powder

• is its hardness

This rock started as molten magma. What type of rock is this?

• Sedimentary

• Igneous

• Metamorphic

This rock was formed by smaller pieces of rock that settled at the bottom of a lake millions of years ago. What type of rock is this?

• Sedimentary

• Igneous

This is a natural solid that is made of one or more minerals.

• Mineral

• Fossil

• Rock

• Sediment

This is the continuous process of rock changing from one type to another.

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

• Rock Cycle

Which of the following lists the steps an igneous rock undergoes in order to become a sedimentary rock, in the correct order?

• Deposition, erosion, melting, cooling

• Erosion, weathering, eruption, cooling

• Dissolving, deposition, cooling, fracture

• Weathering, erosion, deposition, cementation

Limestone is a sedimentary rock. During the rock cycle, limestone is changed into marble, a metamorphic rock. The processes that act on limestone and change it into marble are

• weather and erosion

• heat and pressure

• compacting and cementing

• melting, cooling, and hardening
