Name 3 important properties of Earth's atmosphere.

• 1. Composition: The atmosphere is composed of various gases, primarily nitrogen (78%) and oxygen (21%), along with trace amounts of other gases such as carbon dioxide, argon, and water vapor. 2. Temperature: The temperature of the atmosphere varies with altitude, generally decreasing with height in the troposphere and increasing in the stratosphere due to the absorption of ultraviolet radiation by ozone. 3. Pressure: Atmospheric pressure decreases with altitude, affecting weather patterns and the ability of organisms to breathe.

• 1. The atmosphere is composed of only oxygen and hydrogen, with no other gases present. 2. Temperature remains constant throughout all layers of the atmosphere. 3. Atmospheric pressure increases with altitude, making it easier to breathe at higher elevations.

• 1. The atmosphere is composed of 50% nitrogen and 50% oxygen, with no other gases. 2. Temperature increases with altitude in the troposphere and decreases in the stratosphere. 3. Atmospheric pressure remains constant regardless of altitude.

• 1. The atmosphere is composed of various gases, primarily carbon dioxide and methane, with trace amounts of nitrogen and oxygen. 2. Temperature decreases with altitude in the stratosphere and increases in the troposphere. 3. Atmospheric pressure is highest at the top of mountains.

Oxygen is needed for this natural process that can cause a fire.

• Combustion

• Photosynthesis

• Respiration

• Evaporation

The more oxygen in the air, the [smaller/larger] a fire gets.

• smaller

• larger

What is relative humidity?

• Relative humidity is the amount of moisture in the air compared to the maximum amount of moisture the air can hold at a given temperature, expressed as a percentage.

• Relative humidity is the temperature at which air becomes saturated with moisture.

• Relative humidity is the total amount of moisture in the air regardless of temperature.

• Relative humidity is the difference between the current temperature and the dew point.

Why do some people feel uncomfortable when relative humidity is high?

• Some people feel uncomfortable when relative humidity is high due to the body's inability to effectively cool itself through the evaporation of sweat, leading to a feeling of heat and discomfort.

• High relative humidity causes an increase in oxygen levels, making it harder to breathe.

• High relative humidity leads to a decrease in air pressure, causing discomfort.

• High relative humidity increases static electricity, leading to discomfort.
