Mountains
A mountain is a natural elevation of the earth's surface having considerable mass, often steep sides, and a height greater than that of a hill. Part of the geography of every continent, they are most often found in a long group called a range Some mountain ranges are Alps, Andes, Himalayas, and Rocky Mountains, though there are dozens more.

How many meters is that Grand Canyon above sea level?
No. Mean sea level is an altitude of 0 metres but if I walk a distance of 0 metres that has nothing to do with sea level!
What is the name of the tallest of the volcanic plateau mountains?
The tallest volcanic plateau mountain is Mauna Kea, located in Hawaii. It rises about 13,796 feet (4,205 meters) above sea level and when measured from its base on the ocean floor, it is over 30,000 feet (9,144 meters) tall, making it the tallest mountain in the world.
Mountains grow through tectonic forces, specifically when tectonic plates collide or move past each other. This movement causes the Earth's crust to fold, creating mountain ranges. Additionally, volcanic activity can contribute to mountain growth by depositing layers of molten rock that solidify over time, forming new peaks.
Mountains made of crumpled and folded layers of rock are called?
Folded mountains. These mountains are formed when tectonic plates collide and the layers of rock are pushed together, creating folds and wrinkles in the Earth's crust. Examples include the Himalayas and the Alps.
What are the names of 3 fault block mountains?
- Sierra Nevada in California, USA
- Grand Teton in Wyoming, USA
- Harz Mountains in Germany
How are the mountains in pacific ring of fire different from fold mountains?
Fold mountains are mountain ranges while mountains in the Pacific Ring of Fire consists of mountain ranges, block mountains, volcanic mountains, and other types of mountains as the ring has all convergent, divergent and transform plate boundaries (San Andreas Fault).
Features that have a very high elevation and sometimes is covered in snow?
High mountain peaks are features with very high elevations that are often covered in snow, due to the colder temperatures at higher altitudes. Snow-covered peaks are characteristic of mountainous regions and provide opportunities for activities like skiing, snowboarding, and mountaineering.
What was the land around mount st Helens used for?
The land around Mount St. Helens was primarily used for forestry, mining, recreation, and wildlife habitat before the 1980 eruption. After the eruption, the area has been designated as a National Volcanic Monument and is now primarily used for research, education, and recreation.
What are the names of young fold mountains of world?
Some examples of young fold mountains include the Himalayas in Asia, the Andes in South America, and the Rockies in North America. These mountain ranges are still actively being uplifted through tectonic processes, resulting in their rugged, steep topography.
What is the second most common element in the air?
The most common element in the atmosphere is Nitrogen (N), which is taken in by plants and animals, but is not of any use in cellular respiration, so it is exhaled straight back out during breathing. The second most common element in the air is Oxygen (in the compound, O2), which is needed by the body to carry within the blood to provide oxidation that keeps us alive and powers muscles such as the heart which pumps the blood.
The atmosphere is made up of 78% Nitrogen 21%, Oxygen, and 2% other gases such as carbon-dioxide (a compound, CO2), water vapor (H2O), and other gasses -- including the "noble" gasses such as Helium (He), Argon (Ar), Neon (Ne), and so on.
There are small amounts of gasses such as Chlorine (Cl2) and Flourine (F2), but Bromine (Br) is a liquid and not a gas at room temperature.
How many times has Mauna Kea erupted?
Mauna Kea has erupted at least three times in the past 10,000 years. The most recent known eruption occurred about 4,600 years ago. However, Mauna Kea is considered dormant, not extinct, meaning it could potentially erupt again in the future.
What do you call a someone who studies mountains?
A person who studies mountains is called a geologist or a geomorphologist. They examine the formation, structure, and processes that shape mountain landscapes.
Mountains are formed and change position due to tectonic plate movements. These large landforms can be uplifted through processes like folding and faulting, and erosion can also shape their appearance over time. While mountains themselves do not move in the traditional sense, the Earth's crust beneath them is constantly shifting.
Volcanic gases escape through what type of vent?
Volcanic gases escape through a vent called a fumarole or fissure on the surface of a volcano. This release of gases can occur steadily or explosively, depending on the volcanic activity.
What are two ways plateaus can be formed?
Plateaus can be formed through volcanic activity where lava flows solidify over time to create a flat, elevated surface. Alternatively, plateaus can also be formed through the uplift of large blocks of land, such as through tectonic processes like continental collision or rifting.
How are lassen peak and mount shata related to subduction?
The volcanic chain from southern Canada to Northern California is part of the North Pacific Subduction Zone - the Juan de Fuca plate (and Gorda Plate) are being pushed under the North American plate.
As the plate is pushed down below the NA Plate it melts and has a lot of water in it. Some of this superheated and buoyant material makes its way up the zone above it to the surface of the earth as volcanoes.
This is a great page that explains all the basics about this:

Mount Hekla is a stratovolcano in Iceland that formed through a series of volcanic eruptions over time. Its cone-shaped structure was built up by layers of volcanic ash, lava, and other volcanic materials accumulating over thousands of years. The volcano's frequent eruptions have played a key role in shaping its current form.
Volcanoes are formed usually near plate boundaries, most commonly divergent/constructive plate boundaries, such as the Mid-Atlantic Ridge. Here the crust is moving apart and causing melting due to a decrease in pressure. The magma rises, filling the cracks in the crust and forms fissure volcanoes and sea mounts, which are submarine volcanoes.
Volcanoes also form at convergent/destructive boundaries, like the the rim of the Pacific Ocean known as the Ring of Fire, which contains about 68% of Earth's subaerial volcanoes. A volcano here is formed when a denser, colder oceanic plate, subducts under another plate, either a continental or warmer oceanic plate. The subducted plate will melt under the high temperatures in the mantle. This will form magma, which will in turn form cracks in the plates, which allows the magma to flow out from the mantle into the crust and sometime onto Earth's surface. The lava (when magma reaches the surface it is called lava) will then harden and form layers, slowly forming a volcano.
A shield volcano is formed when there is mafic lava, which has a low silica content, making it less viscous and in turn means it flows quickly over a large area before it cools and hardens; whereas a felsic-lava or composite volcano is formed when there is felsic lava, with a high silica content which in turn increases it's viscosity which means it flows slowly over a small area before it hardens.
Another reason for the formation of volcanoes is the mantle plume theory. A mantle plume is situated beneath the plate, which means it does not move as the plate moves. It is magma source, and magma spews out of it onto Earth's surface to form volcanoes. However, the volcano is situated above the plate, so the volcano moves along with the plate. Since the mantle plume does not move, the volcano becomes extinct as it is cut off from its magma source. A new volcano then forms on top of the hot spot and the cycle continues. Some examples are the Hawaii chain islands and Yellowstone.
Volcanoes are mainly formed along the edge of plates, and most often occur at mid ocean ridges.
Then I will do my best to answer your question: Volcanoes are mostly millions of years old. They are formed by magma, molten rock, being ejected from deep inside the Earth onto the exterior surface of the volcano forming a cone, which may either be steep or not so depending on the viscosity of the magma extruded. A good example for you to research would be the Island of Surtsey, it's just about 45 years old.......
Which two tectonic plates are colliding causing the rise of the Andes Mountains?
The South American Plate and the Nazca Plate are colliding, causing the rise of the Andes Mountains through a process known as subduction. The Nazca Plate is being forced beneath the South American Plate, leading to the formation of the mountain range.
The Himalayan Mountains were formed as a result of what?
The Himalayan Mountains were formed as a result of the collision between the Indian and Eurasian tectonic plates. This collision forced the Earth's crust to crumple and uplift, creating the massive mountain range that continues to grow taller each year.
What plates are causing mt usu to form?
The movement of the Pacific Plate and the North American Plate along the Aleutian Trench is causing the formation of Mount Usu. The subduction of the Pacific Plate beneath the North American Plate is resulting in volcanic activity and the formation of the volcano.
What is the geological age of Green Mountains in Vermont?
The Green Mountains are a part of the Appalachian Mountains which rose about 450 million years ago.
For what is used congloromate rocks?
Conglomerate rocks are used in construction and landscaping. They are often used as aggregate in concrete and asphalt mixes due to their durability and strength. Additionally, conglomerate rocks can be used as decorative stones in gardens and pathways.
