What are Fold Mountains?
These mountains form the northern border of the indian subcontinent. This is a nearly impassable barrier between it and the lands to the north. These ranges are part of vast mountain belts that strech halfway around the world from North Africa, to the Pacific coast of Southeast Asia. The mountains themselves stretch for about 1,500 miles from west to east. It's between Nanga Parbat, in the Kashmir region and Namjagbarwa, in the Tibet Autonomous Region of China. These mountains are bordered to the northwest by the mountain ranges of Hindu Kush, and the Karakoram. To the north of this is the Plateau of Tibet. From the south to the north of the Himalayas vary between 125 and 250 miles. The entire area covers around 230,000 square miles.

What are Volcanic Mountains?
There are different types of volcanic mountains such as: Cinder Cone, Shield, and composite. Cinder cone mountains are made up of material blasted out of the volcano then rains back down. These volcanoes aren't expected to be large. Shield volcanoes are built up by many lava flows. This lava can flow over a large distance causing it to be immense in width. A composite volcano is made up of many layers of ash, rock, and hardened lava. Some of the most famous volcanoes in the world fit into this category.
There isn't just volcanic mountains on Earth. The largest mountain in the entire Solar System is Olympus Mons, which is located on Mars. This is a shield volcano that has grown to be more than 21 km tall.
