Atmosphere

In science class we are studying about the atmosphere. There are 5 layers of the atmosphere: 1. Troposphere, 2. Stratosphere, 3. Mesophere, 4. Thermosphere, 5.Exosphere. The troposphere is where we live in. The troposphere is where weather occurs. The stratosphere is where the ozone layer is. There are few clouds in this layer.


Temperature decreases with height throughout the mesosphere. The coldest temperatures in Earth's atmosphere, about -90° C (-130° F), are found near the top of this layer.The thermosphere extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet.Temperatures climb sharply in the lower thermosphere.Air in the exosphere is extremely thin. That's what we are laerning about in science class.
