The composition of Earth’s atmosphere

78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases

Characterized as decreasing average temperature from ground level up to an average altitude of about 11 km, where the temperature stops decreasing with height.

The layer of Earth's atmosphere above the troposphere, extending 11-50 km above the Earth's surface.

The layer of Earth's atmosphere extending from 50-80 km in altitude, characterized by decreasing temperatures with altitude.

The part of Earth's upper atmosphere about 80 km, characterized by increasing temperatures with altitude.

Difference between Temperature and Heat.

Temperature is a measure of the average speed of molecules or atoms in a substance. Heat is energy being transferred from a warm object to a cold object.

How the atmospheric pressure changes with altitude

The atmospheric pressure varies with altitude as the density of air decreases as we rise up and the air becomes rarer. Atmospheric pressure decreases with increases in altitude.

How the atmospheric temperature changes with altitude.

Near the Earth's surface, air gets cooler the higher you climb. As you climb a mountain, you can expect the air temperature to decrease by 6.5 degrees C for every 1000 meters you gain. This is called the standard (average) lapse rate.

What are jet streams and where are they found

Jet streams are currents of air high above the Earth. They move eastward at altitudes of about 8 to 15 kilometers (5 to 9 miles). They form where large temperature differences exist in the atmosphere.

How the Coriolis Effect affects wind patterns of the atmosphere.

Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect.

The difference between humidity and relative humidity

Humidity is the measure of amount of water vapor in the air. Relative humidity is the ratio of the amount of water vapour in the air to the maximum amount of water vapour the air can hold at that temperature. It is expressed in %

The composition of Earth’s atmosphere	78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases
Troposphere	Characterized as decreasing average temperature from ground level up to an average altitude of about 11 km, where the temperature stops decreasing with height.
Stratosphere	The layer of Earth's atmosphere above the troposphere, extending 11-50 km above the Earth's surface.
Mesosphere	The layer of Earth's atmosphere extending from 50-80 km in altitude, characterized by decreasing temperatures with altitude.
Thermosphere	The part of Earth's upper atmosphere about 80 km, characterized by increasing temperatures with altitude.
