Compare and contrast landslides and mudflows

hope it helps mark me as the brainliest

Explanation:

Both flow rapidly down a slope and can be triggered by an earthquake. Landslides contain only rock and soil, while mudflows contain rock, soil, and a high percentage of water.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
