The troposphere is the lowest layer of the Earth's atmosphere, extending from the Earth's surface up to an average height of about 8 to 15 kilometers. It is where most of the Earth'sweatheroccurs and contains approximately 75% of the atmosphere's mass.
Key Features:
Temperature: The temperature in the troposphere generally decreases with altitude at an average rate of 6.5°C per kilometer, a phenomenon known as the environmental lapse rate.
Explain how Earth's fluid outer core creates the magnetosphere and how this helps protect both humans and technology (such as satellites) from solar winds.
