Question 1

The solar constant is measured at

Accepted Answer

The solar constant is measured at the thermopause, which is the outer boundary of Earth's atmosphere, where the atmosphere is thin enough that solar radiation is not significantly absorbed or scattered.

Question 2

Intercepted solar radiation is called

Accepted Answer

Insolation is the term used to describe the solar radiation that is intercepted by the Earth's atmosphere and surface.

Question 3

The solar constant is measured at

Accepted Answer

The answer of The solar constant is measured at
...

Question 4

The plane of Earth's orbit about the Sun is called the plan of the

Accepted Answer

The plane of Earth's orbit around the Sun is known as the ecliptic.

Question 5

Earth's diameter is

Accepted Answer

According to modern measurements, Earth's diameter is approximately 40,075 km at the equator and about 12,742 km at the poles. Therefore, choice C is the best answer.

Question 6

The uneven distribution of insolation by latitude is primarily a result of

Accepted Answer

Earth's sphericity causes varied angles to parallel solar rays, resulting in uneven distribution of insolation by latitude. The equator receives more direct sunlight than the poles because sunlight has to pass through more atmosphere near the poles, making it less intense. This is known as the angle of incidence, which determines the extent to which sunlight is absorbed or reflected by the atmosphere and the surface. Variability in the Sun's output, changing distance of Earth from the Sun, and variation in the value of a watt may be minor factors affecting insolation but are not the primary reason for its uneven distribution by latitude. Likewise, there is no evidence of long-term decrease in the Sun's energy output that could account for the observed pattern of insolation.

Question 7

Which of the following is true?

Accepted Answer

The equatorial regions receive more solar energy than they emit, leading to an annual net energy surplus.

Question 8

Which of the following is correct relative to insolation at the thermopause?

Accepted Answer

In June, the North Pole experiences continuous daylight, leading to high insolation levels, often exceeding 500 watts per m² per day.

Question 9

What is the name of the location on the surface of Earth that receives insolation when the Sun is directly overhead? (When this occurs,the Sun's rays are perpendicular to this surface. )

Accepted Answer

The location on the surface of Earth that receives insolation when the Sun is directly overhead is called the subsolar point. This is where the Sun's rays are perpendicular to the surface. Option A ("solar point") is not a commonly used term. Option B ("zenith") refers to the point directly overhead an observer, but not necessarily where insolation is perpendicular to the surface. Option D ("North Polar point") and Option E ("Arctic Circle") refer to specific geographic locations and not necessarily where the Sun's rays are perpendicular to the surface.

Question 10

Which of the following results from radiation imbalances at different latitudes?

Accepted Answer

Radiation imbalances at different latitudes create differences in temperature and pressure, leading to the formation of global winds and ocean currents. These in turn can affect weather patterns and contribute to the formation of hurricanes. Therefore, all of the above options are correct.

Question 11

The term "net radiation" refers to

Accepted Answer

Net radiation refers to the difference between the amount of incoming radiation (such as sunlight) and outgoing radiation (such as heat emitted back into space). This balance is important for maintaining Earth's temperature and climate.

Question 12

A langley is

Accepted Answer

A langley is a unit of measurement for solar radiation, specifically an expression of the amount of energy received per unit area (cal/cm²).

Question 13

Do high latitudes receive less energy than the equatorial regions? Why?

Accepted Answer

The orientation of Earth's surface relative to the Sun's rays diminishes the intensity of solar radiation at high latitudes. This is because the angle at which the Sun's rays strike the surface becomes progressively shallower as one moves away from the equator, resulting in a reduction in the amount of energy received at higher latitudes.

Question 14

The solar constant is the value obtained

Accepted Answer

The solar constant is the amount of solar radiation received per unit area at Earth's orbit, which is defined as the average distance from the Sun. This value is approximately 1361 Watts per square meter. It does not change significantly as Earth orbits the Sun, so it is not dependent on B, C, or E.

Question 15

The amount of energy received above the South Pole during the southern hemisphere's summer solstice is ________ than that received above the North Pole during the northern hemisphere's summer solstice because ________.

Accepted Answer

Earth is closer to the Sun during the southern hemisphere's summer solstice, leading to more energy being received above the South Pole compared to the North Pole during the northern hemisphere's summer solstice.

Question 16

Changes in daylength and the Sun's altitude above the horizon over the course of the year

Accepted Answer

Changes in daylength and the Sun's altitude above the horizon over the course of the year are responsible for the seasons. This is due to the tilt of Earth's axis as it orbits around the Sun, causing different parts of the planet to receive varying amounts of sunlight throughout the year.

Question 17

Which of the following is true relative to net radiation at the thermopause?

Accepted Answer

Net radiation at the thermopause is the difference between incoming solar radiation and outgoing longwave radiation. Due to the variation in solar radiation and atmospheric/oceanic circulation patterns, net radiation is not evenly distributed. It has positive values in lower latitudes due to high solar radiation and negative values toward the poles due to low solar radiation.

Question 18

At all times during the year,the circle of illumination

Accepted Answer

The circle of illumination is the dividing line between the illuminated hemisphere and the dark hemisphere of the Earth. Therefore, it divides Earth between equal halves of lightness and darkness.

Question 19

On the northern hemisphere's summer solstice,the north polar region receives ________ daily insolation than areas nearer the equator because ________.

Accepted Answer

On the northern hemisphere's summer solstice, the north polar region receives more daily insolation because the Sun does not set, resulting in continuous daylight.

Question 20

1372 watts per square metre (2 calories per cm² per minute)refers to the

Accepted Answer

1372 watts per square metre (2 calories per cm² per minute) refers to the solar constant, which is the average value of energy received at the thermopause, which is the outermost layer of Earth's atmosphere. This value is important for understanding Earth's energy budget and the amount of energy available for driving atmospheric and oceanic circulation, weather patterns, and climate variations.
