You use a lamp and an orange to predict seasons based on Earth's revolution and axis tilt. Which best describes your investigation?

A.

I move the orange toward the lamp to show why summer is warmer than winter in the Southern Hemisphere.

B.

I tilt the orange toward the lamp to show why summer is warmer than winter in the Northern Hemisphere.

C.

I move the orange away from the lamp to show why winter is colder than summer in the Southern Hemisphere.

D.

I do not tilt the orange to show why regions on the equator get the same amount of sunlight all year.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
