If a mountaintop is 10,000 feet above the valley below we can expect the temperature to be about? a: about 36 degrees f lower b: about 36 degrees f higher c: no change at all, the same d: its impossible to estimate the change in temperature

The correct option is: A: About 36 degrees F lower

Explanation:

The atmospheric temperature of the Earth varies with various factors such as humidity, altitude, radiation, etc.  

The temperature of the Earth's atmosphere changes with height or altitude. As we go vertically up from the surface of the Earth, the atmospheric temperature decreases.

This is because as the altitude increases, the atmospheric pressure decreases and thus the temperature also decreases.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
