1. Temperature cools about 6.5 degrees Celsius per kilometer of altitude/elevation.

To get this answer, you would need to understand the concept of lapse rate, which is the rate at which temperature decreases with an increase in altitude. The standard average lapse rate is approximately 6.5 degrees Celsius per kilometer.

2. The layer that extends from 10 km to 50 km above the Earth's surface is called the stratosphere. This layer contains ozone that absorbs much of the Sun's ultraviolet radiation, providing protection for life on Earth. It also contains most clouds and the jet stream.

To find this answer, you would need to have knowledge of Earth's atmosphere and its different layers. The layer with ozone and clouds is the stratosphere.

3. The atmospheric layers mentioned are the mesosphere, thermosphere, and exosphere.

To know this answer, you would need familiarity with the different layers of the Earth's atmosphere. The mesosphere extends from 50 to 85 km above the surface, the thermosphere extends from 85 to 500 km above the surface, and the exosphere lies beyond that.
