Weather changes occur primarily because of

heat exchange between the ocean and atmosphere.
heat exchange between the sun and atmosphere.
incoming solar radiation.
large quantities of fossil fuels burned in the atmosphere.

Incoming solar radiations

Explanation:

Weather is defined as the condition of atmosphere at any given time. Weather depends upon the temperature, precipitation, air pressure, and cloud covering.

Daily changes in weather comes because of storms and winds while seasonal changes in weather comes because earth revolves around the sun.

As earth is not flat so, when sun shines near the equator region of earth it becomes warm but the polar region at that time is cold because less solar radiations reach that region. Hence, Incoming solar radiations will be the right answer.

c)as speed changes, wavelength and frequency change.

everything changes!

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
