Why are volcanic rocks often exposed at Earth's surface as hills ridges and mountains surrounded by areas of lower elevation?
Volcanic rocks are exposed at Earth's surface as hills, ridges, and mountains because they are more resistant to erosion compared to surrounding rocks. This resistance is due to the harder and denser nature of volcanic rocks, which allows them to withstand weathering and erosion processes better, resulting in the formation of elevated landforms.
Which is denser Oceanic Crust or Continental Crust?
Oceanic crust is denser than continental crust because it is composed of denser rocks like basalt and gabbro, while continental crust is made up of lighter rocks like granite and sedimentary rocks. This density difference is due to the composition and thickness of each type of crust.
What kinds of rocks are mountains made of?
Mountains are made up of many different types of rocks. It also depends on the where the mountain is located and how it formed. For example, mountains formed by recent volcanic activity will be mostly composed of Igneous rock. Though most mountains and the like are made up of a combination of igneous, sedimentary and metamorphic rock.
Mountains made of huge rocks separated from other rocks by fault are mountains?
Mountains formed from large rocks that have been uplifted and moved along fault lines are called fault-block mountains. These mountains are created when tectonic forces cause the earth's crust to break and move in different directions, resulting in the formation of distinct mountain ranges. The movement along faults can result in steep cliffs and rugged terrain characteristic of fault-block mountains.
In undeformed strata where are the rocks typically the densest?
In undeformed strata, the rocks are typically the densest at the bottom of the sequence. This is due to the process of gravitational settling, where denser rocks sink and accumulate at the bottom over time, creating a denser layering pattern in the strata.
What are mountains made of?
Mountains are made of rocks and dirt. They have high, bumpy tops, and they are high in elevation.
What are the Ural mountains made of?
Mountains are made of many different rocks. Such as sedimentary, ingenious and metamorphosis rocks.

This resistance is due to the harder and denser nature of volcanic rocks, which allows them to withstand weathering and erosion processes better, resulting in the formation of elevated landforms.
What are the Himalayas mountains made of?
they are made of different species of rocks
What force keeps mountains from sinking into the mantle?
Mountains are supported by the Earth's crust, which is less dense and floats on the denser mantle beneath. The crust is buoyant and supported by the strength of the rocks and tectonic processes that lift and maintain the mountains at the surface.
Which is denser regular ice or ice with rocks in it?
Ice with rocks in it.
What type of rock are mostly found in mountains?
volcanic mountains are mostly associated with igneous rocks and sedimentary rocks at their slopes can be found due to weathering,but mountains such as fold mountains can contain igneous rocks,metarmophic ro cks and even sedimentary rocks at their slopes
How many mountains are in Ontario?
There are approximately 283 named mountains in Ontario, Canada. These mountains range in height and size, with the highest peak being Ishpatina Ridge at 693 metres in elevation. Ontario’s mountainous regions include parts of the Canadian Shield and the Niagara Escarpment.

Where did sediment come from?
Sedimentary rocks are formed from the erosion of different material from tops of mountains and hills. Sedimentary rocks are formed by the build up and ensuing consolidation of sediments into different types of rocks.
