100
What are the two types of weathering?
Physical weathering and chemical weathering.
100
What is erosion?
Erosion is the moving of particles of rock (or weathered rock)
100
What is deposition?
The laying down of sediment
100
How many ecoregions are there in Texas (not including the marine environment)?
There are 11 ecoregions in Texas, not including the marine environment.
100
True or false: Weathering, erosion, and deposition have no impact on any of the ecoregions.
False
200
What is weathering?
Weathering is the breaking down of rock into smaller pieces.
200
What are the different ways erosion can happen?
Wind erosion, water erosion, waves, gravitational erosion, and glacial erosion.
200
How many ways can deposition occur and what are they?
3 ways: water, wind, and ice.
200
Which ecoregion is named for the color of its soil?
The Blackland Prairie ecoregion.
200
Which ecoregion, due to weathering, has had Palo Duro Canyon carved into the earth over time?
The High Plains ecoregion.
300
True or false: Weathering is a very short process.
False
300
What are 2 examples of erosion?
Any combination of water erosion, wave erosion, bioerosion, glacial erosion, and gravitational erosion.
300
True or false: the forming of a delta at the mouth of a river is an example of deposition.
True
300

In what ecoregion is Enchanted Rock located in?

Hill Country / Edwards Plateau

300

In which ecoregion does the most wind erosion occur?

The Trans-Pecos/Big Bend Country ecoregion (more specifically, the Chihuahuan Desert part of the ecoregion).

400
True or false: An example of weathering is the breaking of a rock due to plant roots.
True
400
True or false: Fast flowing water which carves out a canyon is an example of erosion.
False, it is an example of weathering.
400
True or false: The ocean floor is caused by deposition.
True, because rock and pieces of rock is laid down to form sediment on the ocean floor.
400
Which ecoregion occupies most of the space in the panhandle of Texas?
The High Plains ecoregion.
400
Does weathering, erosion, and deposition have an effect on how the ecoregions are "grouped?"
Yes, because the weathering, erosion, and deposition create landforms that describe each ecoregion in their own ways. Without weathering, erosion, and deposition, there wouldn't be landforms, so the ecoregions wouldn't be much different.
500
What are the different ways weathering can occur, including both the physical and chemical ways?
Ice wedging, exfoliation, thermal weathering, biotic force, oxidation, and carbonation.
500
How are glaciers a way that erosion occurs?
The glaciers pluck and abrade at the ground under the ice, and it picks up the pieces of rock and carries it in the ice to a new destination.
500
What other force is needed in order for deposition to be successful?
Gravity. Without it, the layers of rock wouldn't press together and be compact enough to become sediment.
500
What are the Texas ecoregions?
They are each major ecosystems that are unique in terms of their geography, their ecosystems, their plants and animals. Each ecoregion has something that makes it different from the others.
500
Is it reasonable to predict that in 100 years, weathering, erosion, and deposition will have changed the ecoregions of Texas? Why?
Yes, it is reasonable, because weathering, erosion, and deposition are always happening. In 100 years, it will be expected that the ecoregions will have changed, even if only slightly.
