7. The Central Lowlands are agriculturally very important.​

Answer 1

Answer:

1. Explanation: Bays and gulfs are concavities formed by tidal erosion in the coastline of an ocean, lake, or sea. The difference between a bay and a gulf is not clearly defined, but the term bay usually refers to a body of water somewhat smaller than a gulf.
2. Mount McKinley, or Denali, consists of two peaks that are permanently covered in snow. It is located by a major fault system, known as the Denali Fault, which makes it subject to continual tectonic uplift. A major earthquake in 1912 caused a significant segment of the south face of the mountain to shear off
3. The hydrographic Great Basin is a 209,162-square-mile (541,730 km2) area that drains internally. All precipitation in the region evaporates, sinks underground or flows into lakes (mostly saline). As observed by Fremont, creeks, streams, or rivers find no outlet to either the Gulf of Mexico or the Pacific Ocean.

Answer 2

Answer:

Hope it helps u..

Explanation:

1. ) NORTH AMERICA HAS A BROKEN COASTLINE RESULTING IN THE FORMATION OF BAYS AND GULFS.

2. IT LIES IN THE ALASKA RANGE WHICH IS THE HIGHEST PEAK WHERE IT RECEIVES SUFFICIENT

SNOW FALL THROUGHOUT THE YEAR.

3.) IT IS AN AREA OF INLAND DRAINAGE AND THE RIVERS DRAINS IN THE GREAT BASIN

RATHER THAN OCEAN.

4. IT IS A REGION OF ACTIVE VOLCANOES ALL ALONG THE PACIFIC CIAST OF NORTH AMERICA

AND PRONE TO EARTHQUAKE.

5.  AS IT LIES AT HIGHER ALTITUDE WHICH RECEIVES SNOWFALL THROUGHOUT THE YEAR.

6. ) IT IS A LOW PLATEAU REGION WITH STEEP SIDES AND A NUMBER OF RAPIDS AND

WATERFALL AS WELL AS SWIFT STREAM ARE HARNESSED FOR HYDRO ELECTRICITY

7.  IT IS A VERY FERTILE LOWLANDS WHERE IT IS ALSO KNOWN AS PRAIRIES. AS THE ALLUVIUM

IS DEPOSITED BY RIVER MISSISSIPPI AND MISSOURI.
