# What effect does increased albedo have on the Earth’s climate quizlet?

Contents

Determine how a given change (increase or decrease) in incoming solar radiation, greenhouse gas concentrations or albedo would affect Earth’s energy balance and Earth’s average temperature. More ice=increase albedo=decrease temp. Replacing ice with forests=decrease albedo=increases temp.

## What effect does increased albedo have on the Earth’s climate?

If Earth’s climate is colder and there is more snow and ice on the planet, albedo increases, more sunlight is reflected out to space, and the climate gets even cooler.

## What is the albedo effect quizlet?

Albedo Effect. Albedo is the proportion of radiation that is reflected by a surface (which should result in cooling). It is impacted by the concentration of clouds in the troposphere, which is the lowest level of the atmosphere. Clouds reduce the amount of solar radiation reaching the earth’s surface.

## What do we expect to happen to Earth’s air temperature If the albedo is increased by 50%?

How would a 50 percent increase in Earth’s albedo impact average surface temperatures? Surface temperatures would increase, causing a decrease in surface water and/or ice on Earth, and would thus cause a further increase in albedo. Higher albedo would result in cooler temperatures on Earth.

## What is the Earth’s albedo quizlet?

Earth’s average albedo is 0.3.

## What’s albedo effect?

Albedo is an expression of the ability of surfaces to reflect sunlight (heat from the sun). … Light-coloured surfaces return a large part of the sunrays back to the atmosphere (high albedo). Dark surfaces absorb the rays from the sun (low albedo).

## What causes the albedo effect?

Light surfaces reflect more heat than dark surfaces. This is called the albedo effect. When the Earth’s temperature dropped because of its position in orbit around the Sun, and the tilt of the axis, the ice sheets grew. This in turn caused more heat to be reflected and the ice sheets to expand further.

## What is albedo and why is it important quizlet?

albedo is another name for reflectivity. the albedo of a surface determines how much sunlight will be absorbed and warm the surface compared to another surface that reflects most of the light and does not change temperature. You just studied 12 terms!

## Is albedo important to planetary temperature quizlet?

The albedo effect has a significant impact on our climate. The lower the albedo, the more radiation from the Sun that gets absorbed by the planet, and temperatures will rise. If the albedo is higher, and the Earth is more reflective, more of the radiation is returned to space, and the planet cools.

## How does global warming alter the albedo of the Arctic quizlet?

A surface with a high albedo, such as snow or sand, will reflect more sunlight back out to space. The lower the albedo, the more energy and heat is absorbed. Global warming is causing ice and snow to melt, revealing the land or ocean underneath.

## What is the albedo effect what surfaces have the greatest albedo?

Objects with higher albedo are cooler in temperature and while those with lower albedo are hotter in temperature. White objects, like snow-covered hills, have high albedo (most sunlight hitting the surface bounces back toward space) and dark objects, like pavement, have a low albedo (Otterman, 1977; Angstrom, 1962).

## What is albedo effect and write their effects?

Emission of dust and aerosols from industries, automobiles, forest fire, and DMS (dimethyl sulfur) play an important role in disturbing the temperature level of any region. Aerosols with small particles are reflecting the solar radiation entering the atmosphere. This is known as the Albedo effect.

## Which will increase the earth’s albedo?

The importance of sulfur in the Earth’s atmosphere and environment is well established. Aerosol sulfate is known to alter atmospheric radiative processes due to its role in increasing the Earth’s albedo and as a cloud condensation nucleus and is a component of the sulfur cycle and environmental acidification.

## What is the difference between weather and climate?

Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.

## What is the Earth’s planetary albedo?

Using satellite measurements accumulated since the late 1970s, scientists estimate Earth’s average albedo is about about 0.30. The maps above show how the reflectivity of Earth—the amount of sunlight reflected back into space—changed between March 1, 2000, and December 31, 2011.

## What processes contribute to the earth’s albedo being 30?

what processes contribute to the earth’s albedo being 30%? Reflection and scattering of solar radiation by the atmosphere, clouds, and the earth’s surface.
