d. a glacier
d. a glacier
Which of the following is best classified as a nonrenewable resource?
F Grass
G Aluminum

what is compaction?
process by which pressure from rocks and soil reduces the size of sediments

F Glaciers were responsible for creating the Great Lakes.
G Glaciers create mountains.
H Moving glaciers create valleys.

Which statement correctly describes how a landform is formed?
a. A lake is formed when flowing water carves out the sides of a canyon.
b. A mountain range is formed when glaciers slowly move across the landscape.
c. A delta is formed at the mouth of a river when flowing water slows and deposits sediment.
d. A U-shaped valley is formed when winds pick up and move sediment away from the landscape.
c. A delta is formed at the mouth of a river when flowing water slows and deposits sediment.
Which of the following is a renewable resource?
F Gravel
G Forests
H Graphite
J Diamonds
G Forests
what is a delta?
a landform created when a river meets the ocean, slows down, and deposits sediment
Describe how rivers and streams can create new landforms over time.
Rivers and streams carry water that wears away the land, creating deep channels like canyons and valleys, and they can also deposit sediment to form new landforms like deltas.
Describe what happens during cementation in the formation of sedimentary rock.
During cementation, minerals in water fill the spaces between compacted sediments and act like glue, sticking the sediments together to form solid rock.
Canyons and mesas are two landforms found in the western part of the United States. Which statement best describes how canyons and mesas are similar?
a. Both were formed by slow-moving glaciers.
b. Both were formed by erosion by wind and water.
c. Both were part of a mountain that was weathered by ice.
d. Both were part of a desert that was reshaped by a flood.
b. Both were formed by erosion by wind and water.
Texas is the largest oil producing state in the United States. Because oil is used for a variety of purposes, Texas is considered to have a stable economy. Oil is valuable as a heating and lighting source but is also used to make gasoline to power airplanes, cars, ships, trains, and trucks. Furthermore, oil is used in the manufacture of plastic products and medicines such as aspirin. Which statement below, BEST explains why it is important for people to conserve not only oil but the products derived from oil also?
F. Oil is a fossil fuel, and as such is considered non-renewable, when it is depleted, it will be gone.
G. Oil is a fossil fuel and considered renewable, but it takes a very long time to renew itself.
H. Oil is a fossil fuel and it needs to be used completely up, or it will be wasted staying in the ground.
J. None of the above statements are correct.
F. Oil is a fossil fuel, and as such is considered non-renewable, when it is depleted, it will be gone.
what is erosion?
the movement of weathered sediment by wind, water, ice (glaciers)
