Answer:

temperature

Explanation:

the temp is affected because of the distance from the sun

Answer:

Motion: Planets closer to the sun move faster.

Shape of orbit: Orbits are elliptically shaped and closer planets have shorter orbits.

Explanation:

Motion: Kepler's Second Law (An equal area is sweeped out by a planet's orbit at equal times), meaning that closer parts of the orbit are faster.

How would conditions on Earth be different if its axis did not tilt? *
A There would be no seasons.
B There would be no years.
C There would be no temperature
D The equator would not be as warm in winter.

Answers

If the earth didn't have a tilt, we wouldn't have seasons. Instead, the environment would be unchanging, and the temperature would vary upon latitude. Equatorial regions would be constantly hot and humid, and polar regions would always be cold. There would no variability to the climate as the year progresses.
