The three types of rocks.
What are igneous, sedimentary, and metamorphic rocks.
100
These are made out of minerals.
What are rocks?
100
This is the bottom layer of soil and is mostly made up of rock.
What is bedrock?
100
Melted rock on top of the surface of the earth.
What is lava?
100
This type of soil has the largest particle size and water drains through it quickly.
What is sand?
200
These rocks are made from melted rock that cools and hardens.
What are igneous rocks.
200
This characteristic of a mineral is tested by trying to scratch it and is measured on the MOHS scale.
What is hardness?
200
This layer of soil is made up of decaying organic material like dead animals and plants.
What is humus?
200
Small pieces of rock and other material that are created by erosion and weathering eventually become rocks.
What are sediments?
200
This type of soil has very small particle size and water does not go through it easily.
What is clay?
300
These rocks are formed when other rocks are changed by extreme pressure and heat.
What are metamorphic rocks?
300
The color of the powder left behind when a mineral is ground up.
What is streak?
300
This layer includes the humus and is the top layer of soil.
What is topsoil?
300
The breaking down of rock and other materials by water, wind, freezing, and thawing.
What is weathering?
300
This type of soil has medium sized particles.
What is silt?
400
These rocks are formed when erosion and weathering cause rocks and other materials to break down into smaller pieces that form layers.
What are sedimentary rocks?
400
The way a mineral splits or breaks.
What is cleavage?
400
This layer is below the topsoil and is made up of both organic and inorganic material.
What is subsoil?
400
The movement of rocks from one place to another which breaks them into smaller pieces.
What is erosion?
400
This is the only layer of soil where plant roots do not grow.
What is bedrock?
500
Fossils are most likely to be found in this type of rock.
What is a sedimentary rock?
500
This is the hardest mineral known to man.
What is the diamond?
500
This layer of soil contains most of the nutrients for plants to grow.
What is humus?
500
This is measured by the MOHS scale.
What is hardness?
500
This is a mixture of sand, silt, and clay.
What is loam?
