10. Why does the temperature drop when you rise in altitude? A. There are fewer air molecules and they are moving slower
B. There is a drop in air pressure
C. The molecules are moving very fast
D. Both A&B are correct
There are fewer air molecules and they are moving slower
There is a drop in air pressure
both A & B are correct
The moleucles are moving very fast

A. There are fewer air molecules and they are moving slower

Explanation:

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further and the temperature decreases. If the humidity is at 100 percent  the temperature decreases more slowly with height.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
