How can oceanic sediments became part of continental mountains?

In an ocean-continent convergence, the collision of ocean and continental crust causes the accretion of marine sedimentary deposits to the edge of the continent. These sediments, then, are forced up through normal mountain building orogenic uplift and compression (and faulting). In another method, as the underlying oceanic crust area of a plate tips down at a subduction zone, its ocean-floor sediment can be scraped off along the front edge of the overriding continental plate. The result is an increase in the width and thickness of the overriding plate, and thus, a mountain range. This is seen well at the convergence of the Nazca plate and South American plate (Peru-Chile Trench or Atacama Trench) forming the Andes Mountains - which are actually originally volcanic in origin, but are being buttressed by the new sediments.

Why are ocean fossils found at the top of the rocky mountains?
When two continental plates collide, one has to give and the other rises over the first. It there are fossils in this material, it can be pushed to the highest peaks of mountains. Evidence of this is found in the grand canyon where fossils of ocean creatures anr found many thousands of feet above sea level.
What are two forces that form mountains?
Mountains are most commonly formed by continental-continental convergence. This type of convergence was responsible for the creation of the Himalayas as the Indian subcontinent collided with Asia. Continental-continental convergence does not result in subduction because continental lithosphere is buoyant and less dense than oceanic lithosphere.
What is a continental slide?
A continental slide is the new crust on the earth surface. It happens when two plates below the earth surfaces meets and the boundary became deep trenches.
What happened to continental copper and steel industries inc?
They became CCX. Moved headquarters to Carle Place NY.
What happen to the earth when the mountains of north and south pole became usually warm?
There are no mountains at the North Pole - the 'land' at the North Pole is all under water. There is only surface ice.
How did the Rocky Mountains form?
The Rocky Mountains formed from the collision of the North American and Pacific plates, & uplifting areas of crust to form mountains. They started rising about 80 million years ago. Science, Continental - Continental where 100 million years ago where these two Earth crust collided together and after a while it started building up, and eventually became a mountain. The Rocky Mountains formed west to east, as based on geological evidence. The Appalachian Mountains formed from east to west, again based on geological evidence. The Appalachian Mountains are much older than The Rocky Mountains. The Rocky Mountains contains rock sediments proven to be from The Appalachian Mountains.

Why is continental drift so important?
The continental drift is important because we get to understand more about the structure of the earth and understand how it became to be what it's today. Because without it we wouldn't understand why the lands split apart and became seperate continents.
What is the mountain range that became a border in the proclamation of 63?
The Appalachian Mountains are the range that became a border in the Royal Proclamation of 1763. The Proclamation was issued by the English King and prohibited colonists from settling west of the Mountains.
