Answer:
D. (1) low, (2) absorbs, D. The Poles are tilted most toward or away from the Sun on the Solstices
Explanation:
- Albedo plays a major role in the energy balance of the earth's surface, as it is defined as the rate of absorption of part of solar radiation. Albedo ranges from 0.2 for dark, rough soil surfaces, some of the values around to 0.5 show light soil, and snow has an albedo of 0.75
- Thus most of the solar radiation is absorbed by the soil particles there tectonic rate of sand and snow, in contrast, is very high as compared to the normal dull soil surface.
- The poles are slightly tilted due to the axial rotation of the earth and hence, away from the sun and the solstice that occurs is mostly of lower intensity. As solstice is defined by the declination of sun rays over the surface of the earth when the sun is directly overhead the noon.
Answer:
The electromagnetic radiation per-unit- area increase by 42.65 times.
Explanation:
The radiation per-unit- area (P) is directly proportional to the fourth power of the temperature. Thus,
P ∝ T⁴
For, when the temperature is raised from T₀ to T₁ , the radiation per-unit- area is related to as:
T₀ = 900 K
T₁ = 2300 K
So,
<u>P₁ = 42.65 P₀</u>
<u>The electromagnetic radiation per-unit- area increase by 42.65 times.</u>
Soil is a mixture of rock particles, minerals, decayed organic material, water and air.
