Underwater mountain chains that form where two tectonic plates are pulling apart are called?
Underwater mountain chains that form where two tectonic plates are pulling apart are called mid ocean ridges. The largest is the Mid Atlantic Ridge.
An underwater mountain is known as a "guyot" or a flat topped underwater sea mount. They often do not show up on naval charts and submarines have accidentally run into them. The USS RAY (SSN-653) ran into a coral guyot in the Mediterranean Sea on 20 September 1977 and was severly damaged. so guyot .
Actually, the mountain is the volcano. If the entry point on the surface of the earth were not a volcano, the mountain would have been formed by tectonic plate movement or by another means. The height of the volcano -- rarely called a mountain -- is elevated by the accumulation of lava erupted through its mouth.
The highest mountain range is the Himalayas, The longest mountain range is the Andes(7000km, or 4300 miles long), If you are including underwater mountain ranges the longest mountain range is called the Ocean ridges, it is a chain of mountains that runs on the sea floor of five ocean across the world, the total length of the system is 80000km or 49700 miles.
Fold mountains are formed when two of the Earthâ??s tectonic plates push together. This process is called orogeny. The pressure of the colliding plates force the edges of the plates upward into folds. Fold mountains are the most common type of mountain. It takes millions of years to create a mountain range!
generally speaking, this is caused by earthquakes that force movement of the tectonic plates beneath the surface of the earth. When these plates are forced together it can result in the surface being pushed upward into anything from a small hill to an entire mountain range. The Rocky Mountain Range for example is a result of millions of years of geological activity. Were the two tectonic plate meet is called a Fault Line.
Mars has a mountain called Olympus Mons, an extinct volcano. It has been able to remain high, since the force of gravity on mars, `pulling` the mountain back to the surface, is less. It stands around 27km or 16 miles above the surrounding plains, nearly three times higher than Everest. Its considered the largest mountain in the solar system.
