Which of the following situations would result in angular clasts?
a) transport of the clasts over long distance
b) working of clasts by waves on a beach
c) steep slopes in a mountain
d) dunes formed by wind

c) steep slopes in a mountain

Explanation:

What are angular clast?

The pieces of pre-existing rocks or minerals found in sedimentary rocks are known as clasts.Sedimentary rocks which contains these clasts are called clastic

The shape and how round these clasts are is dependent on how far the rock has been transported from the original source and also dependent non the media of transportation.

Rounded clasts are found in those rocks which have been transported far from their source of origin and have been deposited in a high energy environment such as the ocean in which they get reworked over time.

Rocks with angular clasts have not been reworked and transported for longer distance from the original source which is why it is very likely that we will find them at the foot of the mountain.

d) physical means can be used to separate the components of air.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
