Test: Domains of Earth - Delhi Police Constable MCQ

A "stratovolcanic boundary" is not a recognized type of plate boundary. The correct term is "stratovolcano," which refers to a specific type of volcano.

The Himalayas were formed as a result of the collision between the Indian Plate and the Eurasian Plate.

Convection currents in the mantle, caused by heat from the Earth's core, are the main driving force behind plate tectonics.

The Hawaiian Islands were formed by a hotspot, where magma rises from the mantle, creating a chain of volcanic islands as the tectonic plate moves over the stationary hotspot.

The Theory of Continental Drift, proposed by Alfred Wegener, suggests that continents were once part of a supercontinent called Pangaea and have since drifted to their current positions.

The Earth's magnetic field is not direct evidence for plate tectonics, but it is related to the movement of molten metals in the outer core.

The Earth's magnetic field is generated by the movement of molten iron and nickel in the outer core.

Rifting is the process by which a single tectonic plate breaks apart into two or more separate plates, leading to the formation of a divergent boundary.

The asthenosphere, a partially molten and ductile layer, is located in the upper part of the mantle.

Subduction occurs when one tectonic plate sinks beneath another plate at a convergent boundary.

The Andes mountain range was formed due to the collision of the South American plate with the Nazca plate, making it an example of a convergent boundary.

A normal fault is formed when one block of rock moves downward relative to the other due to tensional forces.

The Mariana Trench, located in the western Pacific Ocean, holds the deepest known point on Earth, known as Challenger Deep.

The Mid-Atlantic Ridge is an underwater mountain range formed by the divergent boundary between the Eurasian and North American plates.

The Ring of Fire is a region encircling the Pacific Ocean known for its high seismic and volcanic activities.

At a divergent boundary, two tectonic plates are moving away from each other, leading to the formation of new crust through volcanic activity.

The hydrosphere includes all water on Earth, including ice (solid state), liquid water, and water vapor (gas state) in the atmosphere.

The theory of plate tectonics explains the movement of Earth's lithospheric plates, which causes earthquakes and volcanic activities at plate boundaries.

The lithosphere includes the Earth's crust and the uppermost part of the mantle, forming a rigid outer shell.

The innermost layer of the Earth is called the inner core, and it is primarily composed of solid iron and nickel due to high pressure and temperature.
