Earthquakes and Volcanoes
Weathering and Erosion
100
A solid substance that occurs naturally in rocks or in the ground.
What are minerals
100
The remains of decayed plants or animals in the soil.
What is humus?
100
This is a natural feature on the Earth's sruface.
What is a landform?
100
This is a mountain that forms as lava flows through a crak onto earth's surface
What is a volcano?
100
The process of moving sediment from one place to another?
What is erosion?
200
What are the 3 types of rocks?
Igneous, Sedimentary and Metamorphic
200
This type of soil has large particles and cannot hold water.
What is sand?
200
These are areas of land that are higher than the land around them. One of them are at least 1,600 ft tall.
What are mountains and hills?
200
The shaking of Earth's surface caused by movement of rock in the crust.
What is an earthquake?
200
The breaking down of rocks on Earth's surface into smaller pieces.
What is weathering?
300
This rock is formed when layers of sediment are pressed together.
What is a sedimentary rock?
300
This type of soil has very small particles, holds lots of water, but cannot hold air.
What is clay?
300
These are lowland areas with higher land around them. One is stretched between mountains and hills, while the other has very steep walls.
What are valleys and canyons?
300
These are the 4 layers of the Earth.
What are the crust, mantle, outer core and inner core?
300
Weathering that is caused by water, wind and temperature.
What is physical weathering?
400
This rock is formed when heat and pressure change an existing rock.
What is a metamorphic rock?
400
This type of soil has medium sized particles and is ideal for growing plants.
What is loam?
400
These are both large areas of flat land. One of them is an elevated (higher) area of flat land.
What are plains and plateaus?
400
This is melted rock under the Earth's crust.
What is magma?
400
Weathering that is caused by acid rain or when metal is exposed to oxygen to become rust.
What is chemical weathering?
500
This type of rock is formed from melted rock that cools and hardens.
What is an igneous rock?
500
This is the method by which fossils are made.
What is the mold and cast formation?
500
These two landforms look very different, but they are both formed by movement of sand and sediment.
What are dunes and deltas?
500
These two landform are created as a result of volcanoes.
What are mountains and islands?
500
These 3 elements of nature are the main causes of erosion.
What are water, wind and ice (glaciers)?
