Which observation about the Rocky Mountains and the Appalachian Mountains would support the claim that exposure of weathering an
d erosion overtime can change land forms? A: The Appalachian Mountains are found in the eastern US and the Rocky Mountains are found near the west coast
B: The shorter and more rounded the Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains
C: The length of the Appalachian chain is about 2,400 kilometers and the Rocky Mountain chain is about twice as long
D: The Appalachian Mountains are composed mostly of sedimentary rocks while the Rocky Mountains also contain other rock types
B: The shorter and more rounded the Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains
Explanation:
The Appalachian mountains form a system of mountains in eastern North America and are older than rocky mountains as they were formed 480 million years ago and are similar to those of the alps. They form a barrier to the east to the west.
They extend to southeast Canada and form zones of 300 miles wide. They form the mountain ranges surrounding hills and the dissected plateaus forming at an elevation of 6,684 meters from the sea level. <u>Whereas the rocky mountains are younger and have an elevation of 4,401 meters.</u>
Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different from the environment. Ectotherms, like lizards and snakes, do not use metabolic heat to maintain their body temperature but take on the temperature of the environment.
