Erosion is the process of wearing away surface materials and doing what to it?
What is moving it somewhere else.
100
What often forms at convergent plate boundaries where plates collide into each other?
Mountains
100
What processes must a metamorphic rock go through to become an igneous rock?
What is melting and cooling
100
How is metamorphic rock formed?
What is when minerals in existing rock are changed by heat and pressure
100
Which type of rock often contains fossils?
Sedimentary rock
200
How did this canyon form?
A river caused physical weathering and the river eroded away the sediment.
200
Combined substances that can usually be separated.
What are mixtures.
200
All rocks can be weathered and become what?
What are sediment?
200
What are the two actions that produce sedimentary rock?
Compaction and cementation
200
Three common fuels that are made from fossils and contribute to climate change.
What are oil, coal, and natural gas.
300
Water, ice, and wind drop newly formed sediments by what process?
Deposition
300
Explain how humans can cause chemical weathering to rocks.
Increased pollution means increased acid rain, which causes chemical weathering.
300
If igneous rock goes under the process of heat and pressure, what does it become? Can it get back to igneous rock in one step?
What is metamorphic rock, and no.
300
What often occurs when plates slide by each other at transform faults?
Earthquakes
300
Which layer of sedimentary rock is most likely to contain the most recent fossils?
The top layer
400
Weathering is processes that work to what?
What is break down rocks
400
Special mixtures that cannot be easily separated usually because one substance dissolved in a liquid.
What are solutions.
400
What are the different types of rock in the rock cycle?
What are igneous, sedimentary and metamorphic
400
How is igneous rock formed?
What is from the cooling and hardening of magma
400
Where would you expect to find the oldest fossils in the layers of sedimentary rock?
The lowest layers
500
What happened to the rock layer underneath this house?
Waves caused physical weathering and erosion from the waves carried the sediment away.
500
Which plate boundary would you find primarily igneous rock?
Divergent Plate Boundary
500
What types of rocks can become magma? Through what process?
What is all of them through melting
500
What is the energy source that scientists believe moves the tectonic plates?
Thermal heat from the mantle
500
What could you infer about the past of land where seashell fossils have been found?
The land must have been covered by seawater in the past.
