What causes changes in weather? a. air masses move and meet. c. water evaporates. b. the air gets more humid. d. clouds form.

Air masses move and meet

Explanation:

The formation, movement, and collision of the air masses is what causes the most noticeable and quick changes in the weather conditions. The air masses can be warm, cold, humid, dry. They form in lot of places around the world, and the place where they form gives their characteristics. The basic rule is that the denser, heavier air masses move toward the less dense, lighter air masses, pushing them up or backward. This results in quick changes in the weather, and literary in minutes there can be complete change from dry and warm, to cooler and wet weather conditions.

The answer is A. air masses move and meet

hope this

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
