Weathering and Erosion
The process where rocks are broken down
What is weathering?
The general cause of acid rain
What is pollution?
The result of a dead plant or animal that gets compacted and cemented between layers of sediment
What is a fossil?
A rock that forms when lava cools so quickly that no crystals form
What is obsidian?
The type of rock that is formed by heat and pressure
What is metamorphic rock?
The name of the material that is formed from weathering and erosion
What is sediment?
Substances that cause acid rain when mixed with moisture in the air
What are sulfur dioxide, carbon, and nitrogen?
This is formed when sediment is compacted and cemented
What is sedimentary rock?
This is formed when lava cools
What is igneous rock?
Energy source responsible for convection currents and heat and pressure
What is the core of the Earth?
The process where sediment is moved by wind, water, or ice
What is erosion?
The pH of acid rain compared to normal rain (higher? lower? same?)
What is lower pH?
The term that describes what has to happen to sediment before it is compacted and cemented
What is deposition?
A coarse crystal rock that is formed when the magma in the Earth cools inside the earth very slowly and the crystals form slowly
What is extrusive igneous rock?
Layer of the Earth usually associated with heat and pressure (location of where it happens)
What is the mantle?
Two specific sedimentary rocks
Possible answers: Limestone, shale, coal, sandstone, chalk, siliciclastic, clay stone, Breccia, conglomerate, Rock gypsum, siltstone, or Quarters
Two rocks most commonly affected by acid rain
Limestone and marble
The materials that allow sediment to be cemented together
Location of magma when it melts
What is under the surface/in the crust/mantle?
If a rock is melted without pressure and made into a new rock is this rock a Metamorphic rock? If not, what type is it?
No because there was no pressure to form the rock so it would be an igneous rock.
