The highest and most extensive mountains are _________.

  1. fold mountain

  2. residual mountain

  3. black mountain

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

Fold mountains are formed due to the folding of crustal rocks by compressive forces generated by the movements inside the earth. Thus fold mountains can be said to be caused by the influence of internal forces. These are the highest and most extensive mountains of the world and are found in all the continents.

Which of the following phenomena causes the shape of the Earth?

  1. Internal structure

  2. Atmospheric pressure

  3. Rotation

  4. Revolution
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Earth is slightly bulged out towards the equator due to the spin. If the rotation stops, the shape might not change immediately, but water and atmosphere would go to the poles making it thicker there. Mid way through the equator and poles, the region will have moderate pressure. Gravity makes it spherical. Earth spin then extends it out at the equator and flattens it at the poles.

The upper part of the earth's crust is called SIAL because ___________.

  1. It is rich in sodium and aluminium

  2. It is rich in silica and aluminium

  3. It is rich in scandium and arsenic

  4. It is rich in sulphur and argon
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The outer or upper layer of the earth's crust is mostly found under the continent. Silica and aluminum are abundantly found in this layer therefore it is popularly known as SIAL. The average density of the layer is 2.75 to 2.90 and the average thickness is 8 to 100 km.

The middle layer of the earth's interior is called _________.

  1. Mantle

  2. Core

  3. Crust

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

Mental is the middle layer of the earth lies between crust and core. The average thickness of this layer is 100 to 2900 km. Silica and magnesium elements predominate in this layer so it is known as SIMA.  Density of the layer varies between 3.1 to 5.00. It has two layers: upper mantle and lower mantle.

The lower part of the crust known as 'Oceanic Crust' is rich in __________.

  1. Aluminium and copper

  2. Magnesium and aluminium

  3. Copper and gold

  4. Silica and magnesium
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sima is the name for the lower layer of the Earth's crust. This layer is made of rocks rich in magnesium silicate minerals. Typically when the sima comes to the surface it is basalt, so sometimes this layer is called the 'basalt layer' of the crust. The sima layer is also called the basal crust or basal layer because it is the lowest layer of the crust. Because the ocean floors are mainly sima, it is also sometimes called the oceanic crust.

The thinnest layer of the earth is ____________.

  1. crust

  2. mantle

  3. inner core

  4. outer core
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the crust is the thinnest layer of the Earth, amounting for less than 1% of our planet's volume

The boundary that separates the mantle from the core is called _________.

  1. Gutenberg Discontinuity

  2. Mohorovicic Discontinuity

  3. Core Boundary

  4. All of these

A Correct answer
Explanation

The Gutenberg Discontinuity is the boundary layer between the Earth's mantle and the outer core, characterized by a significant change in seismic wave velocity.

A Correct answer
Explanation

The Earth's interior is composed of layers based on composition and density: SIAL (crust), SIMA (lower crust/upper mantle), Asthenosphere, Mesosphere, and NIFE (core).

The innermost layer of the earth's interior is called _____________.

  1. SIAL

  2. SIMA

  3. NIFE

  4. Core
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The innermost layer of the earth is core. This central mass mainly made of nickel and iron and therefore is known as NIFE. The density of the layer is 5.1 to 13.00. It is composed of heaviest mineral materials. The core contains 1/3 of the entire mass of the earth. It has two layers outer metallic core and inner metallic core.

The innermost layer of the earth is _______.

  1. crust

  2. core

  3. mantle

  4. magma
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The core is the innermost layer of the earth with density 5.1 to 13.00. It composed of heaviest minerals. This central mass is mainly made of nickel and iron and therefore is known as NIFE. The core contains 1/3 of the entire mass of the earth. The materials of this part may be liquid, plastic or even solid state due to tremendous pressure from above.
