What are the 3 different types of weathering?
Chemical, Physical, & Biological
100
Why is the outer part of Earth continually changing?
Rocks are weathered & new rocks are formed
100
What is plate tectonics?
A theory that suggests that the Earth’s crust is in pieces that float on currents of magma.
100
List the 3 types of rocks.
Sedimentary, Metamorphic, & Igneous
100
A rock form of dead plants and animals that did not rot away.
What are fossils.
200
Does granite or limestone react faster with ran? Why?
What is Limestone. Limestone reacts faster because it is made of calcium carbonate, which makes limestone more soluble than granite.
200
Will the Earth run out of rocks? Why or why not?
NO. The rock cycle is a process which make sedimentary, metamorphic, & igneous rocks are linked together in a never ending cycle that continually repeats itself.
200
What is a transform plate boundary?
A plate tectonic boundary that moves side to side during an earthquake.
200
How are sedimentary rocks formed?
Weathered rock pieces get carried away by wind & water, they are deposited & form a layer of sediment. Over time, the sediment layers compact with pressure & the sediment grains become cemented together to form sedimentary rock.
200
What major category of rock are fossils generally found in?
Sedimentary
300
What can cause rocks to peel off? What type of weathering is it?
Heating & cooling of the rock over & over causes cracks that peel. This is a type of physical weathering
300
Explain how sedimentary rocks change to metamorphic rocks & how metamorphic rocks change to igneous rocks.
Sedimentary rocks get pressed together, deeper into the Earth’s crust & over time they begin to heat up, changing the rock properties & becoming metamorphic rock, then the metamorphic rock mixes with the magma, which hardens into igneous rock, igneous rock weathers & starts over.
300
A plate boundary where two tectonic plates collide/meet and may create mountain building events.
What is a convergent plate boundary
300
How are igneous rocks formed?
Igneous rocks are formed when magma cools.
300
Distorted fossils are generally found in what major category of rock?
Metamorphic
400
Explain freeze-thaw action and how it changes rocks over time.
Freeze-thaw is when water gets trapped in rock, gets cold & freezes but then thaws with warmer temperature. The expanding and contracting causes cracks to get larger within the rock.
400
How have humans changed the Earth?
Mining & extracting rocks for human use has changed the Earth, also, pollution has led to more acidic rain, which quickens the weathering processes.
400
A volcano that is not on a plate boundary.
What is a volcanic hot spot.
400
How are metamorphic rocks formed?
Sedimentary rock changes into metamorphic rock over long periods of time with heat and pressure.
400
What major rock type does not contain fossils?
Igneous
500
Define erosion.
The movement of bits of rock loosened by weathering may fall from the rock face, which changes the shape of the rock
500
What does "igneous" mean?
What is fire-made.
500
Where do most earthquakes happen?
Most earthquakes happen on plate boundaries.
500
How can you tell a metamorphic rock from a sedimentary rock?
Metamorphic rocks often have layers of crystals, the metamorphic rocks are much harder than sedimentary rocks & are not porous.
500
What kind of fossils does coquina contain?
Larger fragments of shells or coral
