Question

What most likely caused the ice ages?
Answers:
the size of tree rings and the amount of pollen grains
solar flares and gassy ejections from the Sun
the tilt of the Earth’s axis and the shape of its orbit
the temperatures of the Sun and moon

Answer 1

Answer:

The tilt of Earth's axis and shape of it's orbit

Answer 2

Answer:

1) The onset of an ice age is related to the Milankovitch cycles - where regular changes in the Earth's tilt and orbit combine to affect which areas on Earth get more or less solar radiation. When all these factors align so the northern hemisphere gets less solar radiation in summer, an ice age can be started.

2) cool and dry

3) the tilt if the axis and the shape of the orbit.

4)Daytime on one side of the moon lasts about 13 and a half days, followed by 13 and a half nights of darkness. When sunlight hits the moon's surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C).
