FOSS Science 5th Grade Quiz: The Air Around Us/The Atmosphere

What is the main component of the Earth's atmosphere?

• Oxygen, which makes up about 21% of the atmosphere.

• Carbon Dioxide, which makes up about 0.04% of the atmosphere.

• Nitrogen, which makes up about 78% of the atmosphere.

• Argon, which makes up about 0.93% of the atmosphere.

What is the relationship between altitude and the amount of oxygen available to breathe?

• The higher one is in the atmosphere, the less oxygen (air) there is available to breathe.

• Altitude has no effect on the amount of oxygen available.

• The higher one is, the more oxygen is available to breathe.

• Oxygen levels increase with altitude.

How does temperature change with altitude in the troposphere?

• Temperature increases with increasing altitude.

• Temperature remains constant with increasing altitude.

• Temperature generally decreases with increasing altitude in the troposphere.

• Temperature fluctuates randomly with altitude.

What is wind?

• Wind is the movement of air from an area of high pressure to an area of low pressure.

• Wind is the flow of water in rivers and oceans.

• Wind is the temperature difference between two locations.

• Wind is the sound produced by moving air.

What would happen to Earth without an atmosphere?

• There would be no life, no air, and more radiation from the sun would harm the planet.

• The temperature would remain constant throughout the year.

• Plants would thrive without the need for air.

• Animals would adapt to live in a vacuum.

What is the greenhouse effect?

• The process by which the Earth’s surface cools due to the reflection of sunlight.

• The warming of Earth’s surface due to the trapping of heat by greenhouse gases in the atmosphere.

• The phenomenon where plants absorb carbon dioxide and release oxygen.

• The increase in Earth's temperature due to deforestation and urbanization.

What are greenhouse gases?

• Gases that cool the atmosphere, such as oxygen and nitrogen.

• Gases that trap heat in the atmosphere, such as carbon dioxide, methane, and water vapor.

• Gases that are released during photosynthesis, like glucose and starch.

• Gases that are found only in industrial areas, such as sulfur dioxide and nitrogen oxides.

What is the difference between the troposphere and the stratosphere?

• The troposphere is the lowest layer of the atmosphere where weather occurs, while the stratosphere is above it and contains the ozone layer.

• The troposphere is the layer where airplanes fly, while the stratosphere is where weather balloons are released.

• The troposphere is characterized by a lack of clouds, while the stratosphere is filled with storm clouds.

• The troposphere is the layer closest to the Earth, while the stratosphere is the layer that contains the most air pollution.

What is the ozone layer?

• A region of the stratosphere that absorbs most of the sun's harmful ultraviolet radiation.

• A layer of clouds that protects the Earth from meteoroids.

• A type of gas that is produced by plants during photosynthesis.

• A region in the atmosphere that contains high levels of carbon dioxide.

What is the role of the atmosphere in protecting Earth?

• It provides oxygen for breathing.

• It protects Earth from harmful solar radiation and helps regulate temperature.

• It creates weather patterns and storms.

• It allows for the growth of plants and animals.
