1 why are these arly glaciations known as the snowball earth

1- why are these arly glaciations known as the snowball earth?
- Because snow storms had snoflakes as big as snowballs
-they formed mostly at the tropics but not at the poles
-the ice sheets reached very low latitudes near the tropics
because earth froze over completely from north to south poles

2.-what aspect of deep time do stratigraphic principles help us address?
-radiometric dating
-sequencing of events
-number of ages of Eons, eras, periods, etc
-Facies of analysis

3.-Find the wrong sentence
-The average day was longer during Precambrian
-there are no rocks older than -200 million years on the oceanic basins
-the tides of the Precambrian were estronger because the moon was closer to earth
-there were at least two more cupersontinents before pangea

4.- Rodinia supercontinet forme during this Eon
-Hadean
-Archean
-Proterozoic
-No choice is correct

5.- Following Bailey\'s rule which of the following is typical environment for the formation of greywacke sandstone?

- Deposited near the areas of rapid erosion, tectonically active
- continental - floodpain and rivers
-Shallow marine in a stable setting, far from active plate boundaries
-identifies an arid climate in the continental interior

Solution

1. Arly glacitation as known as snow balls of earth because

Snow storms are caused in the form of snow ball

As a result of these arly glacitation are occured

This results in the formation of snow ball earth
