- The Earth is surrounded by a blanket of air called the atmosphere.
- The atmosphere is a mixture of gases.
- Ozone keeps most of the sun's harmful ultraviolet rays from reaching the earth.
- Nitrogen, oxygen, and argon are the three most abundant elements in the atmosphere.
- The layer of atmosphere closest to earth is the troposphere.
- About three fourths of the atmosphere is nitrogen.
- The layers of the atmosphere are broken down into five.
- The mesosphere is the coldest layer of the atmosphere.
- The temperature in the troposphere decreases as the altitude increases.
- The troposphere is the atmospheric layer closest to the planet and contains the majority of the mass of the total atmosphere.
- Most atmospheric ozone is concentrated in a layer in the stratosphere, about 20-30 km above the Earth’s surface.
- The closer we get to the ground, the higher the atmospheric pressure due to the weight of air particles above.
Parent Tip: Review the logic above to help your child master the concept of layers of the atmosphere worksheet for kids.
