The ionosphere begins around 80 kilometers (50 miles) above the Earth's surface and extends up to about 1,000 kilometers (620 miles) into the atmosphere.
FALSE. The layers of the atmosphere begin with the troposphere (surface to about 10 km), and continue outward with the stratosphere, mesosphere, and thermosphere. The outermost layer, the exosphere, is sometimes included in the thermosphere, as is the ionosphere.
magnetosphere.
No, mountains that are formed when molten materials reach the earth's surface through a weak area in the crust are typically referred to as volcanic mountains. Fault-block mountains, on the other hand, are formed by the movement of tectonic plates along faults, resulting in blocks of crust being uplifted or dropped down.
asthenosphere
Snow can start to melt at 38 degrees Fahrenheit, as long as the air temperature remains above freezing. When the temperature rises above freezing, the snow will begin to melt.
