Which of the following is evidence that supports the idea of uniformitarianism?
Flooding causes higher than normal erosion rates during wet years.
Rates of soil erosion are much lower during droughts that last several years.
Rates of soil erosion are much approximately the same over a period of many years.
Flash floods cause erosion by washing away the top layer of soil in wet years.
What factor(s) change a mountain's shape from jagged and high to round and lower over long periods of time?
deposition
weather and erosion
movement of continents
collisions between continental plantes
When matter gains energy (gets hotter), how does that affect the density?
The matter becomes less dense.
The matter becomes more dense.
Density isn't affected.
What is a convection current?
the transfer of energy by direct contact.
the transfer of energy by the movement of matter
the transfer of energy through a solid, such as Earth's crust
the transfer of energy from a region of lower temperature to a region of higher temperature.
Which of the following occurs because of convection current?
Tectonic plates on the crust move.
Pressure in the crust increases.
The mantle increases in size.
Pressure in the crust decreases.
This principle states that younger rocks lie above older rocks if the layers have not been disturbed.
Index Fossils
Compaction & Cementation
The Law of Superposition
The Law of Crosscutting Relationship
True or False: Because we rarely witness dramatic changes to the Earth, we can conclude that the Earth is not changing very much.
True
False
The processes involved in the rock cycle include all of the following except:
Condensation
Erosion
Weathering
Compaction
True or False: Fossils found in the same layer of rock are from the same time period.
True
False
What happens to magma that is heated by the core?
It rises.
It sinks.
Plate Tectonics
It becomes part of the inner core.
When matter loses energy (gets cooler), how does that affect density?
The matter becomes less dense.
The matter becomes more dense.
Density isn't affected.
Look at the image. The two continental plates are colliding. Why is the Indian Plate moving under the Eurasian Plate?
It's larger.
It's molten.
It's more dense.
It's less dense.
True or False: Disturbances, such as an intrusion or fault, are older than the rock surrounding them.
True
False
Which of the following is considered a slow geologic change?
Tsunami
Weathering
Earthquake
Volcanic Eruption
What processes create sedimentary rock?
Compaction and Cementation
Weather and Erosion
Melting and Cooling
Heat and Pressure
