Question

Explanation / Answer

All of the above is the more accurate answer

The glaciation which we are discussing is considered to be the last ice age.

The meteroite impact which was considered so havoc that it causes extinction of dinasours and other speices also causes a angular tilt, which also affect the angle of radiation and amount of radiation.

Current direction was also altered ,so all of this finaly lead to glaciation which we known as last ice age
