Question

Which of the following is a characteristic of glacial till?

a) Layers of well-sorted sediment
b) The presence of very fine, laminated shale
c) Very sticky silt
d) Very poor sorting, with large clasts suspended in a fine-grained matrix

Answer 1

Glacial till is characterized by very poor sorting, with large clasts suspended in a fine-grained matrix. It does not have distinct layers or well-rounded grains, and it is not sticky silty clay.

correct answwer is d

Step-by-step explanation:

Glacial till is characterized by very poor sorting, with large clasts suspended in a fine-grained matrix.

This means that the sediment is made up of a mixture of different-sized particles, ranging from large boulders to fine-grained material, all jumbled together.

Unlike well-sorted sediment, glacial till does not have distinct layers or well-rounded grains.

It is also not sticky silty clay, as the fine-grained material in glacial till is not cohesive enough to form a sticky consistency.

correct answwer is d
