Question

Examine figure above which shows the depth of the Columbia River before and after the 1980 eruption. How thick was the sediment deposited at the mouth of the Cowlitz River? (in meters)

Why can mudflows travel so much farther than avalanches (or debris flows)?

Look at figure above which shows the path taken by the Osceola mudflow on Mt. Rainier.

What is the longest distance traveled by the mudflow (in kilometers).
(Measure the actual path the flow took from the summit of Mt. Rainier, in kilometers. Note that the part of the mudflow near the summit is covered with younger deposits and is not shown on the map, and that Sumner is the farthest extent of the flow. In other words, follow the longest path from the summit to Sumner.)

The average flow rate for mudflows is 40 km/hr. At this rate, using the map in the previous question determine how long would it take a mudflow to reach the town of Greenwater? (Show your calculations.)

At this rate, how long would it take a mudflow to reach the town of Auburn? (Show your calculations.)

Explanation / Answer

For part 1 i need image or figure image is not uploaded ....

but for second part

Why can mudflows travel so much farther than avalanches (or debris flows)?

Its simple reason is that mudflows is hot , so hot liquid is more mobile and versatile ,avalanche has small crystalls of snow

Let me remind you about mudflows

A mudflow or mud flow is a form of mass wasting involving "very rapid to extremely rapid surging flow"[1] of debris that has become partially or fully liquified by the addition of significant amounts of water to the source material

i undeerlined the fact

secondly it contain

Mudflows contain a significant proportion of clay, which makes them more fluid than debris flows.

thirdly :

it contains lots of water

For rest of the problems please provide the map its not showing either provide the link for the same
