The answers are:
1. Compaction - grains move closer together.
2. Foliation - parallel alignment of platy grains.
3. Recrystallization - grains take on a larger size.
4. Burial metamorphism - when a rock changes because of surrounding pressure.
Compaction produce rocks that have a tighter grain arrangement due to heat and pressure the rock undergoes. This process reduces the size of the rock.
Foliation occurs when pressure is put on one side of the grains more than any other direction. This creates platy structured rocks, which align under pressure.
Recrystallization is a process where the chemical composition a rock is changed. The mineral grains that are produced in this process are larger than the original grains.
Burial metamorphism occurs when rocks get buried deeper and deeper. They change due to the pressure from the overlying layers.

What do you mean 40 m ?? I was trying to solve it, but it’s kinda confusing
Answer:
The point on the rim
Explanation:
All the points on the disk travels at the same angular speed , since they cover the same angular displacement in the same time. Instead, the tangential speed of a point on the disk is given by
where
is the angular speed
r is the distance of the point from the centre of the disk
As we can see, the tangential speed is directly proportional to the distance from the centre: so the point on the rim, having a larger r than the point halway between the rim and the axis, will have a larger tangential speed, and therefore will travel a greater distance in a given time.
