Insolation and Temperature: Horizontal & Vertical — Flashcards

Answer

Insolation refers to the incoming solar radiation that reaches the Earth's surface in the form of short waves. It is the primary source of heat and energy for Earth. Although the Sun emits vast amount…

Answer

The atmosphere is not heated directly by the Sun because solar radiation (insolation) passes through the atmosphere with minimal absorption. Instead, the Earth's surface absorbs this energy and then r…

Answer

The angle of incidence is the angle at which the Sun’s rays strike the Earth’s surface. When the angle is high (near vertical), solar energy is concentrated over a small area, leading to higher insola…

Answer

Longer daylight duration means more time for the Earth's surface to receive solar radiation, increasing total insolation. For example, equatorial regions receive nearly 12 hours of sunlight year-round…

Answer

Transparency of the atmosphere refers to how easily solar radiation can pass through it. It depends on cloud cover, dust particles, water vapor, and pollutants. Thick clouds reflect and absorb sunligh…

Answer

Terrestrial radiation is the long-wave infrared radiation emitted by the Earth’s surface after it absorbs solar energy (insolation). Unlike short-wave insolation, this long-wave radiation is readily a…

Answer

Insolation is the incoming short-wave solar radiation from the Sun, while terrestrial radiation is the outgoing long-wave heat radiation emitted by the Earth. Insolation heats the Earth's surface, but…

Answer

The four processes are: 1. **Radiation**: Energy transfer through space (e.g., Sun to Earth). 2. **Conduction**: Direct heat transfer from Earth’s surface to adjacent air. 3. **Convection**: Vertical …
