How do glaciers cause erosion and deposition

Answers

when glaciers (slowly) glide down a mountain they carry down earth and rock and brings it down. After the glacier has completely melted the earth from the mountain id deposited to the lower ground.

Like flowing water, flowing ice erodes the land and deposits the material elsewhere. Glaciers cause erosion in two main ways: plucking and abrasion.
Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice.
The other way you'll need more informations because my Knowledges are limited by here.

Answers

A base is a substance that has the tendency to release OH- ions. These ions then attract protons to form water.

For example:

NaOH is a strong base which dissociates into Na+ and OH- ions.

NaOH → Na+ + OH-

The OH- ions can then grab the H+ ions from water, thereby reducing the hydrogen ion concentration and increasing the pH

Ans :

When a base is added to water, hydrogen ions decrease.

The answer is decrease.

Which of the following is NOT something that Earth's atmosphere protects us from? A. meteoroids B. ultraviolet light C. greenhouse gases D. dangerous particles from space

Answers

Answer:

The correc answer is C. greenhouse gases.

Explanation:

The atmosphere is a layer of gases that surrounds our planet and is one of the essential elements for life on it.

The atmosphere protects us from harmful solar radiation from the Sun. The Sun, in addition to light and heat (infrared radiation), emits other radiation such as gamma rays, X-rays and ultraviolet rays that are harmful to life. These harmful radiations are absorbed by the atmosphere.

The atmosphere also protects us from the impacts of meteorites. These are from outer space are attracted by gravity and fall on the earth's surface. Upon coming into contact with the gases of the atmosphere, at high speed, the friction causes them to heat up so much that they become incandescent and end up disintegrating, avoiding reaching the ground. Only the largest (rare) can pass through the atmosphere and reach the ground.

Something similar happens that with meteorites occurs with the dangerous particles of space.

Greenhouse gases contribute, to a greater or lesser extent, to the increase of the greenhouse effect, since they are capable of absorbing the heat energy carried by long-wave radiations that are reflected by the Earth's surface.This phenomenon prevents the solar energy constantly received by the Earth from returning immediately to space and causing the temperature of the air near the ground to rise. Then there are changes in the climate such as sea level rise, changes in rainfall, disappearance of forests, extinction of organisms and problems for agriculture.

So the correc answer is C. greenhouse gases.

the answer in C. Greenhouse Gases. Greenhouse Gases is caused by the trapped heart in the atmosphere harming us which we will always have. hope this helped
