Lithosphere MCQ Question and Answer | Geography MCQ Question

Batholiths and Laccoliths are formations of Igneous rocks. A batholith is the largest of the intrusive bodies. They are larger than 100 square kilometers and usually form granite cores. laccolith is a dome shaped intrusive body that has intruded between layers of sedimentary rock. The rising magma forces the overlying layers to rise up into a dome.

The igneous rocks are formed due to granitisation. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Granitization, formation of granite or closely related rocks by metamorphic processes, as opposed to igneous processes in which such rocks form from a melt, or magma, of granitic composition.

The Himalayas were formed due to folding of the geo-syncline named Tethys. 225 million years ago (Ma) India was a large island situated off the Australian coast and separated from Asia by the Tethys Ocean. So it has orginated from the Tethys Geosyncline . the sediments of this folded due to the northward movement of the Indian plate against the Eurasian Plate.

The Japanese archipelago is located in an area where several continental and oceanic plates meet. This is the cause of frequent earthquakes and the presence of many volcanoes and hot springs across Japan.

The Longest Mountain Chains in the world is Andes. The Andes of South America is the longest mountain range in the world, stretching for an estimated distance of 7,000 km (4,350 miles).

A seismograph is the device that scientists use to measure earthquakes. The goal of a seismograph is to accurately record the motion of the ground during a quake.

The Richter scale is used to rate the magnitude of an earthquake, that is the amount of energy released during an earthquake.

Examples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite.

Magma is extremely hot liquid and semi-liquid rock located under Earth's surface. When magma flows onto Earth's surface, it is called lava.

An archipelago sometimes called an island group or island chain, is a chain, cluster or collection of islands, or sometimes a sea containing a small number of scattered islands.
