Answer:
the answer to this question is b
The difference between speed and velocity is that velocity is speed with a direction vector associated with it. It's that direction vector that makes them different. Let's back up a bit and review. Speed is displacement (distance traveled) per unit time. Velocity is displacement (distance traveled) per unit time in a given direction. The "directionallity" associated with velocity makes it a vector quantity, while speed is a scalar quantity.
The matching of the term in column 1 to the characteristics in column 2 is as follows:
- Ice Sheet ----- Continent-sized.
- Moraine ----- Rock piles left by glaciers.
- Contour Planting ----- One way to prevent soil erosion.
- Retreating ----- Shrinking in a glacier.
<h3>What is Contour planting?</h3>
Contour planting may be defined as an endurable way of farming that utilizes the planting across a slope following its elevation contour lines around the hill. It is one of the most common method for preventing soil erosion and increasing soil fertility.
A moraine is an accumulation of debris or rock piles that are left by glaciers after melting.
Retreating is a process that involves the activities which are utilized at the time of shrinkage of glaciers or solidification of glaciers.
Therefore, it is well described above.
