​

Answer:

1. Glacial erratic rock

2. 198 ft

3. Basalt rocks

4. 12,000 to 18,000 years ago

5. A series of potholes and puddles

6. Useless for planting

7. Sudden, short-lived, violent events

Explanation:

Glacial erratic rocks are rocks transported from their source of origin and deposited in their current location by ice rafting over a distance of hundreds of km in the great Missoula floods. These types of rock vary in size when compared to the native rocks.

The Palouse Fall in Washington stands at an height of 198 feet through which the water plummets, and is surrounded by striking basalt cliffs. It lies on the Palouse River upstream of the confluence with the Snake River.

Most of the Inland Northwest bedrock is made up of basalt rock that shot shot out of a crack in the earth's crater as a liquid lava and the solidified 15 to 17 million years ago.

Due to the great flood, most of central Washington when viewed from space looks like a series of puddles and potholes.

Early farmers regarded the scabland as useless and rather planted their wheat on the silt rich hill.

Catastrophism is the theory that the Earth has largely been shaped by sudden, short-lived, violent events, which differs from Uniformitarianism that believes in slow incremental changes of the earth's surface with time
