The Earth is divided into three main layers. The dense, hot inner core, the molten outer core, the mantle, and the thin crust, which supports all life in the known universe.

Interior of the earth:

• Earth's interior is generally divided into three major layers: the crust, the mantle, and the core.
• The hard, brittle crust extends from Earth's surface to the so-called Mohorovicic discontinuity, nicknamed the Moho.
• The Moho is not located at a uniform depth, but about 10 kilometers (6 miles) below the seafloor and about 35 kilometers (22 miles) beneath the surface of continents.
• Beneath the Moho is the mantle, the viscous layer that makes up more than half of Earth's volume.
• The mantle is divided from the core by the Gutenberg discontinuity, about 2,880 kilometers (1,798 miles) beneath Earth's surface.
• The outer core is molten and liquid iron and nickel, while the inner core is solid and much denser than either iron or nickel at the surface.
• The crust forms only 1 percent of the volume of the earth, 84 percent consists of the mantle and 15 percent makes the core

Hence, the correct sequence of the layers of the earth by their volume in decreasing manner is Mantle → Core → Crust

Additional Information

The correct answer is The US.

• The Grand Canyon is an example of a valley that is an erosional landform.
  • Erosion - It is the geological process in which earthen materials such as soil or rock are removed and transported by natural forces such as wind or water.
    • Valleys start as small and narrow rills.
    • The rills will gradually develop into long and wide Gullies.
      • A rill means a small stream.

​

• The gullies will further deepen, widen, and lengthen to give rise to valleys.
  • Gully - A small passage formed due to stream.

• Depending upon dimensions and shape, many types of valleys like V-shaped valleys, gorge, canyon, etc. can be recognised.
  • V-shaped valley 

• A canyon is characterised by steep steplike side slopes.
• A canyon is wider at its top than at its bottom. In fact, a canyon is a variant of a gorge.
• Valley types depend upon the type and structure of rocks in which they form.
  • Example - canyons commonly form in horizontal bedded sedimentary rocks and gorges form in hard rocks.
• The Grand Canyon :

• Gorge - A narrow valley with steep sides and a river running through it.

The correct answer is Thermosphere.

Key Points

The atmosphere consists of different layers with varying densities and temperatures. The column of the atmosphere is divided into five different layers depending upon the temperature condition.
They are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

• The troposphere
  • It is the lowest part of the Earth's atmosphere in which all tropical changes take place. It contains about 75% of the total air in the atmosphere.
  • This layer contains dust particles and water vapor.
  • All changes in climate and weather take place in this layer.
  • This is the most important layer for all biological activity.
  • The zone separating the troposphere from the stratosphere is known as the tropopause.
  • The temperature here is nearly constant, and hence, it is called tropopause.
• The stratosphere
  • It is found above the tropopause and extends up to a height of 50 km.
  • One important feature of the stratosphere is that it contains the ozone layer.
  • This layer absorbs ultraviolet radiation and shields life on the earth from an intense, harmful form of energy.
  • The stratopause caps the top of the stratosphere.
• The mesosphere
  • It lies above the stratosphere, which extends up to a height of 80 km.
  • In this layer, once again, the temperature starts decreasing with the increase in altitude and reaches up to minus 100°C at a height of 80 km.
  • The upper limit of the mesosphere is known as mesopause.
• The thermosphere 
  • It is located between 80 and 400 km above the mesopause.
  • It contains electrically charged particles known as ions, and hence, it is also known as the ionosphere.
  • Radio waves transmitted from the earth are reflected back to the earth by this layer.
  • It contains Ions and helps in wireless communication
• The temperature here starts increasing with height.
• The exosphere
  • It is the uppermost layer of the atmosphere.
  • This is the highest layer but very little is known about it.
  • Whatever contents are there, these are extremely rarefied in this layer, and it gradually merges with outer space.

​

The correct answer is outer core.

Important Points

• The interior of the earth is divided into three parts namely Crust, Mantle, and Core.
• The core is the innermost layer of the earth.
• The radius of the innermost layer(core) is about 3500 km.
• The core is made up of material constituted by nickel and iron.
• The temperature and pressure of the central core are very high.

Key Points

• The core is further subdivided into two layers called the outer core and inner core.
• The outer core of the earth is in a liquid state.
• The inner core is in solid-state
• The outer core is responsible for the earth's magnetic field.

Additional Information

• The crust is the outermost of the earth.
  • It is brittle in nature.
  • it the thinnest layer of Earth.
  • The thickness of the crust varies under the oceanic and continental areas.
• The mantle is the second layer in the interior of the earth.
  • The mantle extends from Moho’s discontinuity to a depth of 2,900 km.
  • The upper portion of the mantle is called the asthenosphere.

The correct answer is thermosphere.

Key Points

• The thermosphere lies above the mesopause and is a region in which temperatures increase with height.
• Thermosphere:
  • In the thermosphere, the temperature rises very rapidly with increasing height.
  • The ionosphere is a part of this layer.
  • It extends between 80-400 km. This layer helps in radio transmission.

Additional Information

• There are a total of five atmospheric layers. These are -
  • Troposphere.
  • Stratosphere.
  • Mesosphere.
  • Thermosphere.
  • Ionosphere: the lowest part of the Thermosphere contains the ionosphere.
  • Exosphere.
• Stratosphere:
  • It lies beyond the troposphere, up to an altitude of 50 km from the earth's surface.
  • The temperature in this layer remains constant for some distance but then rises to reach a level of 0°C at 50 km altitude.
  • This rise is due to the presence of ozone.
  • This layer is almost free from clouds and associated weather phenomena, making conditions most ideal for flying aeroplanes.
• Exosphere:
  • This is the uppermost layer of the atmosphere extending beyond the ionosphere above a height of about 400 km.
  • The air is extremely rarefied and the temperature gradually increases through the layer.
  • Light gases like helium and hydrogen float into space from here.
• Troposphere:
  • It is the lowermost layer of the atmosphere.
  • The layer starts at Earth's surface and extends 8 to 14.5 km high (5 to 9 miles).
  • The troposphere contains dust particles and water vapour.
  • This is the most important layer of the atmosphere because all kinds of weather changes take place only in this layer.
  • The zone dividing troposphere from the stratosphere is known as the tropopause.
