The atmosphere is the air around the Earth. We find rain, cloud, fog and wind in the atmosphere. Earth’s atmosphere make life possible.
The atmospheric is made of many gases. It contains in three forms: a gas, called vapour, ice crystals and droplets. Nitrogen 78%. Oxygen 21%. Other gases 1%. Other gases: Argon, neon, kypton and xenon, and harmful chemicals like nitrogen dioxide.
The TROPOSPHERE is where weather occurs. You brea the the air in the troposphere. Many airplanes fly in the STRATOSPHERE because it is very stable. Many rocks fragment from space burn up in the MESOSPHERE. The THERMOSPHERE is very thin. The upper limit of four atmospkere is the EXOSPHERE.
A tiny number of gases in the atmosphere can trap heat around the Earth. The traced gases regulate the climate. Not all the heat we feel on Earth comes from the Sun. As Earth warms up, it gives heat as low-energy infared rays. The greenhouse gases trap most of infared rays. Without greenhouse gases, Earth’s surface temperature would -18.
THE CONSEQUENCES… 1. Our glaciers are melting. 2. Our cities are flooding. WE NEED TO MAKE A CHANGE. 1. Recycle and reuse. 2. Consider alternative energy methods. GLOBAL WARMING is when the greenhouse effect gets stronger, the Earth’s average temperature rises.
Most governments are worried about rising greenhouse gas levels in the atmosphere, and the effect they may have.
1. Switching off the lights when leaving a room.2. Turning down your central healting thermostat by as littel as one degree.
