Sun: The ultimate source
Activity
You have learnt about the various factors influencing the distribution of temperature
like latitude, altitude, nearness of ocean and winds. Based on this give reason for this
following statements.
A. The amount of solar energy decreases as we move from tropical region to poles.
B. The places situated at higher altitudes experiences lower temperature.
C. The range of temperature is low in places situated near to the oceans and high in interior regions away from sea.
D. Winds influence atmospheric temperature.
Answers
Explanation:
A. It receives less solar radiation than the equator because the angle of incidence is much smaller. The sun's rays do not strike the Earth's surface as directly at the North Pole; they are less focused. ... The difference in the amount of solar energy the land receives causes the atmosphere to move the way it does.
B. High-altitude regions, such as mountainous places, experience low temperatures. Earth's surface absorbs heat energy from the sun. ... Therefore, the layers of atmosphere closest to Earth's surface (low-altitude areas) are typically warmer compared to layers of atmosphere in higher-altitude areas.
C. Therefore, areas near the ocean generally stay cooler during the day and have a more moderate temperature range than inland areas. Heat capacity is the amount of energy required to raise the temperature of a substance by 1°C. This activity demonstrates that water has a higher heat capacity than sand.
