how can you tell the difference between old mountains and young mountains?

Young mountains, created several dozen million years ago, have steep slopes and high-pointed peaks. The youngest mountains, also the highest in the world, are within the Himalayas massif in Asia. Old mountains, in contrast, have rounded peaks and slopes made gentler by hundreds of millions of years of erosion.

Describe the difference in the angle of subduction between old and new plates. The young oceanic crust has a greater angle going into the ground then the old oceanic plate does. ... the transform movement is moving the plates in opposite direction but in a vertical direction.

The You Yangs Ranges are not the remains of a volcano. More than 400 million years ago, the area now known as the Western Volcanic Plains was under the sea. ... The granite that forms the You Yangs Ranges was originally a mass of magma that had worked its way up into the surrounding sedimentary rocks.

['Scandinavian Mountains: 1,762 kilometers (1,095 miles)', 'Carpathian Mountains: 1,500 kilometers (900 miles)', 'Alps: 1,200 kilometers (750 miles)', 'Caucasus Mountains: 1,100 kilometers (683 miles)', 'Apennine Mountains: 1,000 kilometers (620 miles)']

To calculate the elevation of a mountain, scientists would measure the distance between two points on the ground and then measure the angles between the top of the mountain and each point. "If you have two angles, you know the third, because the sum of the angles is 180 [degrees]," Molnar told Live Science.

The one major difference between them is that the whole mountain system of Himalaya represents a very youthful topography with high peaks, deep valleys and fast-flowing rivers whereas the peninsular plateau is composed of igneous and metamorphic rocks with gently rising hills and wide valleys.

Upwarped mountains are generally the result of broad arching of the crust or sometimes great vertical displacement along a highangle fault. ... Fault‐block mountains result from tensional stress. They are bounded by high‐angle normal faults, and usually form a series of horsts and grabens.

The Adirondack Mountains, which are made of rocks that show little deformation, are -uplifted mountains-. Volcanoes that form over -hot spots- are often solitary and are far from tectonic plate boundaries. -Uplifted mountains- are regions of broad uplift that seem to be related to rising convection cells in the mantle.

Mountains are high and rugged and plains are basically flat. ... Mountains are substantially - noticeably - taller than the surrounding 'level' land. Plains are level (near-flat to gently rolling) large areas. The difference in elevation in a plain between the lowest and highest points is rarely over a few hundred feet.

Aravalli ranges are an example of Residual mountains. Residual mountains are those mountains which have been eroded by the agents of degradation such as winds, rain, frost and running water. The hard rocks that are left behind are called residual mountains.

The Himalayas are known as the young fold mountains because they have been formed only few million years ago. They were formed because of the folding of the earth's crust due to tectonic activity (fold mountains are formed when two tectonic plates collide with one another).

Region 4: The Cascade-Sierra Mountains. The rocks of the Cascades and the Sierra Nevada are primarily igneous, since they resulted from melting above a subduction zone. The Cascades are younger mountains, having first appeared 36 million years ago, and are still forming today.

Isotopic analyses of these rocks suggest that the Appalachian Mountains are eroding away so slowly that the difference in relief between summits and river valleys is growing, not shrinking. ... “We think of the Appalachians as a range in decline, dying away and becoming more of a muted topography,” Hancock says.

Time is the biggest difference. Glacier theories suggest the world is much older than the Bible does. Also the glacier theories often discount the flood.

As adjectives the difference between young and elder is that young is in the early part of growth or life; born not long ago while elder is comparative of old: older, greater than another in age or seniority.

Mountains are made when Earth's crust is pushed up in big folds or forced up or down in blocks. Mountains form over the course of millions of years. ... There are fold, block, dome, and volcanic mountains. Mountains are jagged because they are constantly eroded by the weather, which wears the rocky surface away.

A young fold mountain range is generally between 10 and 25 million years old while an old fold mountain range can be over 200 million years old. Old fold mountains are usually lower elevation and can appear more like rolling hills such as the Appalachians.
