Question 1

Albedo is a constant 30 percent everywhere on Earth.

Accepted Answer

Albedo varies across different regions and surfaces of the Earth. For example, snow and ice have a high albedo, while forests and oceans have a lower albedo.

Question 2

All objects,regardless of temperature,radiate energy.

Accepted Answer

This is known as blackbody radiation, where all objects emit electromagnetic radiation due to their temperature through a process called thermal radiation.

Question 3

The earth is continuously receiving heat from the atmosphere as well as from the Sun.

Accepted Answer

The Earth receives heat from both the atmosphere (due to the greenhouse effect) and from the Sun, primarily through radiation. This heat is crucial for many processes on Earth, including the water cycle, weather patterns, and the survival of living organisms.

Question 4

The answer of conduction scattering convection radiation...

Question 5

The atmosphere is an efficient absorber of the longer wavelengths of terrestrial radiation.

Accepted Answer

The atmosphere is an efficient absorber of the longer wavelengths of terrestrial radiation, such as infrared radiation. This is one of the reasons why the greenhouse effect occurs, as these longer wavelengths are trapped in the atmosphere, leading to an increase in global temperatures.

Question 6

Tiny solid and liquid particles suspended in the atmosphere are collectively called aerosols.

Accepted Answer

Aerosols can include dust, smoke, pollen, volcanic ash, and more.

Question 7

Weather and climate are synonymous terms.

Accepted Answer

Weather and climate have different meanings. Weather refers to the short-term atmospheric conditions in a specific area, while climate refers to the long-term patterns of temperature, precipitation, and other atmospheric phenomena in a region.

The answer of Tropic of Cancer Equator Arctic Circle Tropic...

Question 9

Distance variations between Earth and the Sun are very important in understanding seasonal temperature variations.

Accepted Answer

Seasonal temperature variations are primarily due to the tilt of Earth's axis, not the distance from the Sun.

Question 10

Considering the albedo of various surfaces,compare daily temperature ranges and means for an urban area to a more rural setting of crops and forests.Also,are there any other factors other than albedo that might affect these temperature variations?

Question 14

Objects that are good absorbers of radiation are not good emitters of radiation.

Accepted Answer

Objects that are good absorbers of radiation are also good emitters of radiation, according to Kirchhoff's law of thermal radiation.

Question 15

The fraction of the total radiation encountered that is reflected by a surface is called its ________.

Accepted Answer

The answer of The fraction of the total radiation encountered...

Question 16

The line separating the dark half of Earth from the lighted half is called the ________.

Accepted Answer

The answer of The line separating the dark half of...

Question 17

The movement of Earth in its orbit around the Sun is referred to as ________.

Accepted Answer

The answer of The movement of Earth in its orbit...

Question 18

Radiant energy is very different depending on its wavelength.

Accepted Answer

The answer of Radiant energy is very different depending on...

Question 19

Isotherms are more irregular in the Southern Hemisphere than in the Northern Hemisphere.

Accepted Answer

Isotherms are generally more irregular in the Northern Hemisphere due to the larger landmasses, which cause greater temperature variations compared to the Southern Hemisphere, which is dominated by oceans.
