Describing Earth’s Atmosphere + Describing Weather

Earth atmosphere has only one layer, and this is what makes earth unique.

What is the name of the atmospheric layer closest to Earth’s surface?

The temperature of the troposphere decreases as you move away from Earth.

Which earth atmosphere layer is above troposphere?

Which earth atmosphere layer has a high concentration of ozone?

The presence of the ozone layer causes the stratospheric temperatures to decrease with altitude.

Ozone has three oxygen atoms and absorbs the Sun’s ultraviolet rays more effectively than oxygen.

Ozone protects Earth from ultraviolet rays that can kill plants, animals, and other organisms and cause skin cancer in humans.

Which earth atmosphere layers is the arthest from Earth’s surface where pressure and density are so low that individual gas molecules rarely strike one another?

Gravity push the atmosphere away from Earth, which is creating air pressure.

In the stratosphere, temperature decreases as altitude increases because of the high concentration of ozone.

In the mesosphere, as altitude increases, temperature again decreases.

In the thermosphere and exosphere, temperatures increase as altitude increases.

Weather can't change quickly or be the same for several days in a row.

Temperature and rainfall are just two of the variables (ตัวแปร) used to describe weather.

Air temperature is the measure of the total kinetic energy of molecules in the air.

Molecules in warm air move slower than molecules in cold air.

Air pressure is the pressure that a column of air exerts (apply) on the air, or surface, below it.

As air moves from areas of low pressure to areas of high pressure, it creates wind.

Meteorologists measure wind speed using an instrument called an anemometer.

The amount of water vapor in the air is called __________.

When the humidity is high, there is less water vapor in the air.

The dew point is the temperature at which air is fully saturated (100% humidity) because of decreasing temperatures while holding the amount of moisture constant.

Clouds are water droplets or ice crystals suspended in the atmosphere.

A cloud that forms near Earth’s surface is called dew point.
