E. Give short answers for the following questions.
1. What are the main elements of weather and climate?
2. How is the atmosphere heated?
3. What do you mean by humidity in the atmosphere? How do we express it?
4. Name the different forms of condensation and precipitation.
Answers
Answer:
1.there are six main components, or parts, of weather. They are temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness.
2.Conduction in the Atmosphere
Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface.
3.Humidity in the atmosphere: ... Relative humidity is defined as the ratio between the actual amount of water vapor present in the air at a given temperature and the maximum capacity of air to hold moisture at that temperature. Relative humidity is always expressed in while absolute humidity determines the amount.
4.Condensation is a phenomenon that occurs when air shrinks so much that it is no longer able to capture and hold humidity. Water molecules are pressed (forced) out of the spaces between the air molecules. As a result, we see vapor (e.g. "giving out", damping, dew, mist, clouds) or water (e.g. rain, hail, snow).
Answer:
- There are six main components, or parts, of weather. They are temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness.
- Heat at Earth's Surface Scattering occurs when a light wave strikes a particle and bounces off in some other direction. About 3 percent of the energy that strikes the ground is reflected back into the atmosphere. The rest is absorbed by rocks, soil, and water and then radiated back into the air as heat.
- Humidity is a measure of the amount of water vapor in the air. Relative humidity measures the amount of water in the air in relation to the maximum amount of water vapor (moisture). The higher the temperature, the more water vapor the air can hold. Relative humidity is what your morning weather reporter would refer to.
- After condensation the water vapour or the moisture in the atmosphere takes one of the following forms — dew, frost, fog and clouds. Condensation takes place when the dew point is lower than the freezing point as well as higher than the freezing point.
