Geology and Earth Structure

1,345 Questions

Geology and Earth Structure explores the physical composition of the planet, including its layers, tectonic plates, and seismic activity. This topic is a core component of geography and general science sections in various competitive exams. Reviewing these concepts builds a solid foundation for answering questions related to natural phenomena.

Geology and Earth Structure Questions

Multiple choice physics save energy types of sources of energy renewable and non-renewable resources renewable and non-renewable sources of energy

What are hot spots?

  1. Molten rock in the earths crust is pushed upward and trapped in certain regions

  2. Solid rock in the earths crust is pushed upward and trapped in certain regions

  3. Molten rock in the earths crust is pushed downward and trapped in certain regions

  4. Solid rock in the earths crust is trapped in certain regions
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Geothermal energy is the energy stored in the earth as heat. It can be harnessed only from a few places on earth called as geothermal hotspots. In these hotspots, molten rock in the earths crust is pushed upward and trapped in certain regions.
Multiple choice

What land forms is likely to occur at the zone of subduction?

  1. Active volcano

  2. block mountain

  3. rift valley

  4. mountain trench
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Subduction zones occur where tectonic plates collide and one plate dives beneath another. This process generates intense heat and pressure, creating active volcanoes through melting rock and magma rising to the surface.

Multiple choice geography water bodies study of water pollution threats to water resource pollution and environment

A rift valley is formed mainly due to ___________________.

  1. forces of tension in the earth's crust

  2. the subsidence of the floor of a river valley

  3. the valley formed after the formation of fold mountains

  4. the deepening of a valley by ice action
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A rift valley is formed mainly due to the subsidence of the floor of a river valley. A rift valley is formed on a divergent plate boundary, a crustal extension or spreading apart of the surface, which is subsequently further deepened by the forces of erosion.


A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault. A rift valley is formed on a divergent plate boundary, a crustal extension or spreading apart of the surface, which is subsequently further deepened by the forces of erosion.

Multiple choice geography water bodies study of water pollution threats to water resource pollution and environment

The process of subduction produces a _________ in sea.

  1. Fold

  2. Valley

  3. Trench

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The process of subduction produces a trench in sea.
The process by which ocean floor sinks beneath a deep-ocean trench and back into the mantle is called subduction (sub duk shun). As subduction occurs, crust closer to a mid-ocean ridge moves away from the ridge and toward a deep-ocean trench. Sea-floor spreading and subduction work together.

Multiple choice geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

Terrestrial radiation is long waves _________.

  1. radiated by the earth

  2. reflected by the earth

  3. both A and B

  4. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Radiation is the direct heating by the transmission of the heat waves. The upper layer of the atmosphere absorbs some amount of heat of the sun as they pass through the atmosphere. Radiation from the earth is called terrestrial radiation. Terrestrial radiation is long wave radiated by the earth. 

Multiple choice evs when there is a disaster disaster and types disasters forest fire

The seismic waves produced in a sea is known as

  1. Tsunami

  2. Earthquake

  3. Flood

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, typically due to earthquakes or volcanic eruptions.

Multiple choice evs when there is a disaster disaster and types disasters forest fire

Which of the following is the main cause of earthquake?

  1. Change in temperature and pressure below the ground level

  2. Floods

  3. Draught

  4. shifting of tectonic plates
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Earthquakes are caused by tectonic movement of rock plates in the earth where the rock plates also known as tectonic plates either break at a point of fault or rub against the other thus causing shaking of the ground.
So, the correct answer is 'shifting of tectonic plates'
Multiple choice evs when there is a disaster disaster and types disasters forest fire

The point of the origination of an earthquake is known as

  1. Cyclone

  2. Epicentre

  3. Seismic wave

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The point within the Earth where an earthquake rupture starts is called the hypocenter or focus, while the point directly above it on the surface is the epicenter.

Multiple choice evs when there is a disaster disaster and types disasters forest fire

Which of the following cause can be related to an earthquake?

  1. Friction between the plates of the earth

  2. Tremors due to the internal movements of plates

  3. Increased sea level

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Earthquakes are primarily caused by the movement of tectonic plates, which involves friction and tremors as they slide past or collide with each other.
