Why are there different seasons?

Earth's tilt results in the Northern hemisphere facing the Sun and away from the Sun

The moon intercepts the Sun and Earth, resulting in different weather patterns

The ellipse along which Earth travels is lopsided, resulting in the Earth being closer to the Sun at different times

The Earth is at different parts of its orbit

7.

5 points

8.

5 points

Exponential growth can be described as

...growth that causes the scarcity of another species

...growth that perpetually accelerates

...growth that accelerates until a point of maximum growth
