Answer:
1. Humidity is the amount of water vapor in the air. If there is a lot of water vapor in the air, the humidity will be high. Relative humidity is the amount of water vapor actually in the air, expressed as a percentage of the maximum amount of water vapor the air can hold at the same temperature.
2. Climate is the long-term average of weather, typically averaged over a period of 30 years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation.
3. The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.
4. Temperature refers to the hotness or coldness of a body. In specific terms, it is the way of determining the kinetic energy of particles within an object.
5. Earth's Atmospheric Layers :
- Troposphere. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles).
- Stratosphere. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high.
- Mesosphere.
- Thermosphere.
- Ionosphere.
- Exosphere.
