What is soil?
What is a combination of decayed organic matter, weathered rock, minerals, water, and air.
100
What are the three types of rock?
Sedimentary, Igneous, and Metamorphic
100
What is continental drift?
The movement of the Earth's continents to their positions.
100
What are the two types of weathering?
Mechanical and Chemical
100
What are three different severe weather we learned about?
Volcanoes, Earthquakes, Floods
200
What are the three types of soil?
Loamy, Clay, and Sandy
200
How are igneous rocks formed?
When hot magma cools.
200
What is the landmass that was all the land on Earth 200 million years ago called?
Pangea
200
What is weathering?
The process that breaks rocks into smaller and smaller pieces.
200
What do floods do to rocks and soil?
Floods ruin the soil, take up the soil and rocks and move them to another place.
300
Why is soil important?
Most of our food is grown in soil. We also need plants to breathe.
300
True or False: During the rock cycle, any given rock can change into any of the three major rock types.
True
300
What are the two layers over Earth that contain plates?
Lithosphere and Asthenosphere
300
What is erosion?
Process in which materials on Earth are worn away and transported from one place to another.
300
What is an earthquake?
The vibrations produced by breaking rocks.
400
When we did our experiment on soil what were the three things that we tested?
pH, water filtering, and squeeze test.
400
What does non foliated and foliated mean?
Non-foliated-no layers Foliated- layers
400
What are faults?
A place where sections of the crust of the Earth move relative to each other
400
What is climate?
Weather pattern in an area over a long period of time.
400
Draw and describe how a volcano erupts (from storing magma to erupting).
Magma is stored under the earth. Heat and pressure push the magma to the top. When magma reaches the top it is called lava and then it erupts.
500
What are the five factors that affects soil formation?
Climate, Types of Rock, type of vegetation, amount of time rock has been weathering, and slope of the land
500
What is the rock cycle?
The rock cycle shows the slow process of how rocks change over time.
500
What are the three types of faults?
Normal faults, Reverse Faults, Strike-Slip Faults
500
How do plants and animals affect the surface of the earth?
As plants grow they increase the size of the cracks on Earth. Animals burrow in the ground loosening sediment and pushes it to the surface.
500
Choose either earthquakes or volcanoes and describe how it changes the surface of the Earth including rocks and soil.
Volcanoes Earthquakes Take up trees, burn down trees, lava hardens over the land, ruins the soil, carries the rocks and soil from one place to another.
