Page 1: Rocks can be classified based on texture. The size of the grains in a rock affects its texture. Coarse-grained rocks have large grains, and fine-grained rocks have small grains. Rocks formed from magma under Earth’s surface have larger grains than rocks formed from lava on Earth’s surface. This is because magma cools slower underneath the ground than it does above ground.

Page 2 What kind of rock is this? Where would this rock most likely be formed? To which group of rocks would this rock belong?

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
