Explanation

Wind blows from areas of high pressure to areas of low pressure.

This is because air molecules move from areas of higher concentration (high pressure) to areas of lower concentration (low pressure) to equalize the pressure difference.

This movement of air is what we feel as wind.

Explanation

A mature tree absorbs carbon dioxide at a rate of 48 pounds per year.

In one year, an acre of forest can absorb twice the CO2 pgroduced by the average car's annual mileage.

Explanation

According to Boyle's Law, for a fixed mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume

. This means that if you decrease the volume, the pressure will increase, and vice versa.

Mathematically, it is expressed as: P1V1 =P 2​ V2  where  P is the pressure, and V is the volume.

Therefore, if the volume decreases, the pressure will increase.
