Question

PLEASE HELP ME NOW!!!! (NOT FOR BEGINNER)

1.What factor increases the likelihood of a landslide occurring?
A.lots of water
B.forest fire
C.all of the above
D.over steepening of a hill

2. Are landslides be considered a fast or slow geological process?
A. Slow, because it takes all winter for the snow to build up.
B. Slow, because all of the snow has to melt before a landslide can happen.
C. Fast, because rain falls fast.
D. Fast because conditions for landslides happen within months, slow processes can take millions of years.

3.The average elevation of the Grand Canyon is 2,200 feet above sea level. Which of the following could be an explanation of why there are fossils at the top of the canyon?
A. The canyon was once covered by the ocean but the land receded (went down)
B. The canyon was covered by the ocean and the water receded (went down).
C. It is still part of the ocean, that’s why there are marine animals there.
D. All of the fossils came from things that lived in the Colorado River.

4. Why does the Grand Canyon have layers?
A. The uplift of the land caused layers.
B. Deposition of sediments over millions of years.
C. Erosion by wind has worn away sedimentary rock.
D. Erosion by the Colorado River has formed layers.

Answer 2

1. C.

2. D

3. D.

4. D.

Step-by-step explanation:

1. Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.

2. Landslides are geologic phenomena that can happen suddenly or through imperceptively slow downslope movement. ... A "translational" landslide can happen rapidly and result in all of the soil on a hillside being stripped off and filling the area at the bottom of the slope.

3. Sedimentary rock contains fossils because it was built up layer upon layer, often trapping and preserving animals, plants, footprints, and more within the layers of sediment.

4. The Uplift of the Colorado Plateau. The Kaibab Limestone, the uppermost layer of rock at Grand Canyon, was formed at the bottom of the ocean. ... The action of plate tectonics lifted the rocks high and flat, creating a plateau through which the Colorado River could cut down.

Hope this helps! :D
