Troposphere

Explanation: The Troposphere: The Layer in Which We Live

The lowest layer of the atmosphere, which lies next to the

Earth’s surface, is called the troposphere. The troposphere is also

the densest atmospheric layer. It contains almost 90% of the

atmosphere’s total mass! Almost all of the Earth’s carbon dioxide, water vapor, clouds, air pollution, weather, and life-forms

are in the troposphere. As shown in Figure 4, temperatures vary

greatly in the troposphere. Differences in air temperature and

density cause gases in the troposphere to mix continuously.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
