Question

What are the reasons why temperature vary between Alaska, Congo, Cochin and Lucknow?

Answer 1

Hint: The term "temperature" refers to a physical quantity that describes how hot or cold something is. When a body comes into contact with another that is colder or hotter, it is the manifestation of thermal energy, which is present in all matter and is the source of the occurrence of warmth, a flow of energy. A thermometer is used to determine the temperature.

Complete answer:
The reasons behind the temperature difference in Alaska, Congo, Cochin and Lucknow are mainly due to:
- Earth's equatorial regions, which face the sun directly, will receive more power per unit of area than regions that face the sun at an angle.
- Areas that receive more power will heat up faster than areas that receive less. The weather is driven by the temperature difference and the movement of heat from warm to cold areas.
- The earth's surface is not perfectly even, and different regions have different albedos or surfaces that absorb different amounts of energy. Areas that absorb more energy are generally warmer than areas that absorb less (such as snow, which reflects a lot of energy back into the atmosphere). Because water takes more energy to heat up than rock, some regions warm-up or cool down faster due to their surface type. For example, large areas of land warm up much faster than an equivalent area of sea. As a result, air masses form, which are broad regions of the atmosphere.

The differences in temperatures between Alaska and Congo, Cochin and Lucknow are due to differences in latitudes and altitudes. Although they all have a maritime influence, their latitudes and altitudes, as well as vegetation cover, determine the temperature differences between those locations.

Note: The sun heats the earth unevenly because it is a sphere. Whenever the light comes on the Earth, the region directly facing the sun (equatorial regions) receives more power per unit of area than a region at an angle to the sun. Areas that receive more power will heat up more than those that receive less. This heat difference, as well as the movement of heat from warm to cold areas, is what drives the temperatures.
