discribe how the rocky mountains were created?

Answer 1

Each crudely ringed pattern was created by the Tertiary erosion of Paleozoic and Mesozoic sedimentary rocks that once overlay and now surround a core of uplifted Precambrian granite.

The Rocky Mountains took shape during a period of intense plate tectonic activity that formed much of the rugged landscape of the western United States. Three major mountain-building episodes reshaped the west from about 170 to 40 million years ago (Jurassic to Cenozoic Periods). The last mountain building event, the Laramide orogeny, (about 70-40 million years ago) the last of the three episodes, is responsible for raising the Rocky Mountains.

Yeah, makes sense to me too. Read more:

Answer 2

About 70 million years ago, a construction project called the ‘Laramide mountain building’ began. Forces deep within the earth shifted, causing Precambrian rocks, granitic behemoths dating a billion years old to move upwards, thousands of feet. The uplifts created huge plateaus, giving the pounding weather much to feast on. For millions of years, wind and rain ate away at the plateaus, slowly chipping away at the sides, covering the surrounding terrain in debris. The uplifts were humbled, some completely buried in their own debris, and the entire region was granted a mild topography.
This continued until the mid-tertiary period, when beginning about 28 million years ago, the whole region was uplifted once again: 5,000 feet further from sea level. The weathering did not change, and with the new elevation, mountains and peaks were formed into what we see today. Softer rock quarries were fully eroded away by the strong hand of wind and rain, creating enormous valleys. The hardened rock that lay in between held firm, resulting in what we call today, ‘hogbacks.’ Among the region are several types of rock formations, but the most prominent are the reddish-colored rocks that define much of the region.
These rock formations are in fact the “fossils” of the original Rocky Mountains, known as the “Ancestral Rockies.” The mountains we know as the Rockies are not the first mountains to claim this real estate. Built around 300 million years ago, the Ancestral Rockies went through the same building and eroding process as the Rockies we see today. Their sediments remained in an oxygen-rich environment, rather than ending up underwater or ground, causing the iron present to oxidize, creating a mineral called hematite, which is, not coincidentally, red. Geologic history can predict, with some great accuracy, what may next claim the land on which the present-day Rockies sit.

Answer 3

Plate tectonics - the same things that cause islands to be formed. Plates shift over millions of years, and as they collide, push areas upward. This is the same way all the mountains of the world were created.

Answer 4

The Rockies run along the continental divide.
2 Techtonic plates are colliding and the earth is pushed upwards creating mountains.
Beyond that you should do your own homework. Last time I checked getting the answers from someone else is cheating.

Answer 5

the rocky mountains were created by the earths structure and because of earthquakes

Answer 6

its to do with the tetonic plates which form the covering of the planets lower levels. the plates are shifting all the time, this is why we get earthquakes. when the plate collide, one will slide over the other and push up the rocks, hence causing mountains.

Answer 7

first answer is right to some degree but most mountains are formed by the movement of tectonic plates. You need to google this subject and do your own homework.

Good luck

Answer 8

Tectonic plates collide and push up the earth over time. That's the simple answer at least, I'm not sure if you need more info?

Answer 9

Snow.It Dried Up.(VERY UNUSIAL).It was sooooo cold the snow dried up and turned into rocks sooo it made the rocky mountains.Also we can say God made it.

Answer 10

God was bored and took a huge chunk of land in his hand and crumpled it like a piece of paper. Now, we have a huge chunk of wrinkled land we call The Rockies.
