Question

1. Some agents of transport can move sediment that ranges widely in grain size. Match the letter of the transport agent from the left-hand column with the maximum grain size it can transport listed in the right-hand column. (Hint- the larger the grain size, the stronger the transport mechanism must be. Generally faster moving water=stronger transport mechanism- glaciers are unique in being able to move extremely large grains, albeit slowly). a) House-sized block ___turbulent stream during a flood b) Boulder ___very slow-moving stream c) Cobble ___ocean waves or desert winds d) Sand ___glacial ice e) Silt ___quiet water f) Mud ___fast-moving stream

Answer 1

Answer:

1. Ocean Waves or Desert Winds - boulders
2. Quiet Water  - Mud
3. Fast Moving Stream - Sand
4. Glacial Ice - House sized block
5. Very slow moving stream - silt
6. Tubulent Stream during a flood - Cobble

Explanation:

1. Glacial ice can transport rocks as big as a house. It has very high transport competence and moves very slowly across a very large distance.  
2. The maximum size of particles that a stream can transport is defined as stream competence. This is a concept under hydrology. Streams depending on its velocity can carry sand, mud, silt and cobble along with the dissolved and suspended load.  
3. The process by which Ocean waves transport sediments, large pebbles and boulders is referred to as Coastal Transportation. During Coastal transportation, large pebbles and boulders are rolled along the seabottom, while beach material is bounced along the seabed.
