Which layer of the soil would be most affected by weathering and erosion? Top/middle/bottom of the soil
Top
100
This is what sedimentary rocks start off as.
What is sediment?
100
These are rocks that can become metamorphic rocks.
What are sedimentary, igneous, and other metamorphic rocks?
100
What are the three categories all rocks can be put into.
What are igneous, sedimentary, and metamorphic?
100
This can happen due to the land poor farming practices such as overgrazing of cattle. It can also occur when plants and trees are removed from the soil.
Desertification
200
All of theses happen on the surface except for which of the following...Cooling of lava. Erosion of sediments. Deposition of sediments. Cooling of magma.
Cooling of magma
200
The movement of sediment from one place to another
What is erosion?
200
These two things are required for a metamorphic rock to form.
What are heat and pressure?
200
A rock that was sediment, then went under pressure, then was melted down and crystalized or cooled inside a volcano is this type of rock.
What is a igneous rock?
200
Growth of cities due to people moving from rural areas into more populated areas.
Urbanization
300
Which of the following is an example of chemical weathering?
-Roots of trees growing in rock.
-Acid precipitation
-Animals burrowing in the ground
-Ice wedging
acid precipitation
300
The process of compaction and cementation forms which type of rock?
Sedimentary rock
300
Sandstone, a sedimentary rock, must go through this to become metamorphic rock.
What is heat and pressure?
300
These rocks can become sediment by weathering.
What is any type of rock?
300
This is caused by logging, farming, and mining on land that was once covered with tress.
Deforestation
400
Which of the following is an example of physical weathering?
-Carbonic acid
-Abrasion by wind and water
-Oxidation (rust)
-Acid rain
Abrasion by wind and water
400
What type of sedimentary rock do we primarily have under us here in Florida?
limestone
400
T/F. Igneous Rock must be formed after metamorphic rock.
False. Igneous rock can be any rock type before it becomes Igneous rock
400
This is formed when
What is slate?
400
Urbanization and Deforestation lead to this.
Land Degradation
500
Any rock can be converted into sediments, which is caused by what?
Weathering
500
30 trees are cut down (deforestation) from 5 different plots of land. The trees are then divided evenly and sold to 3 different lumber mills where they will turned into building materials? How many trees does each lumber mill have?
50
500
This type of rock can be extrusive, meaning it forms on land or intrusive, meaning it forms beneath the surface.
Igneous rock
500
Sedimentary rock is formed by these two factors.
Pressure and cementation or compaction and cementation
500
Deforestation can lead to these two things and the land can no longer support life.
