Bcoz.. In meiosis ti change ploidy of cell from diploid(n) to haploid(2n) .. 2 division occur.. This helps in formation of haploid gametes.. When two gametes fuse.. They form diploid (2n) zygote. 
On the other hand..
 There is only one division in mitosis...bcoz no change in ploidy.. Use in growth. Bcoz it retains nucleo-cytoplasmic ratio.

Answer: They are called Moraines
Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.
Glaciers constantly move on land and they do this under their own weight.
As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.
The resulting hill formed as a result of this soil movement is called a Moraine.
A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.
