Show answer
Correct Option: C
Explanation:

  • Earth began to form over 4.6 billion years ago, from the same cloud of gas (mostly hydrogen and helium) and interstellar dust that formed our Sun, the rest of the solar system and even our galaxy.

  1. Liquid

  2. Solid

  3. Both A & B

  4. None of these

Show answer
Correct Option: A
Explanation:
  • The outer core of the Earth is a fluid layer about 2,300 km (1,400 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle.

The core of earth is 2900 to 6376 kms in thickness. It is composed of _____.

Explanation:
  • The core is 2900-6376 kms in thickness.

How is the inner core of the earth?

geography the earth and the graticule general idea about earth space around the earth is the earth round?

  1. Liquid

  2. Solid

  3. Both A & B

  4. None of these

Show answer
Correct Option: B
Explanation:


  • So, even though it is hotter in the inner core, the pressure in the core is also higher, and you can have solid iron-nickel instead of liquid.
  • It is made of iron and nickel. 
  • This is above the Earth's solid inner core and below the mantle. Its outer boundary is 2,890 km (1,800 mi) beneath the Earth's surface..
  • Convection of liquid metals in the outer core creates the Earth's magnetic field.

Supercontinent Pangaea broke up to form ______.

geography the earth and the graticule general idea about earth space around the earth is the earth round?

  1. Laurensia

  2. Gondwana Land

  3. Both A & B

  4. None of these

Show answer
Correct Option: C
Explanation:
  • Many earth scientists use the term "supercontinent" to mean "a clustering of nearly all continents".
  •  This definition leaves room for interpretation when labeling a continental body.
  • The landmass of   Pangaea is the collective name describing all of these continental masses when they were most recently in proximity to one another.
  • This would classify Pangaea as a supercontinent. According to modern definitions, a supercontinent does not exist today. Supercontinents have assembled and dispersed multiple times in the geologic past (see table). 
  • Laurasia was the more northern of two supercontinents (the other being Gondwana) that formed part of the Pangaea supercontinent around 335 to 175 million years ago (Mya).
  •  It separated from Gondwana 215 to 175 Mya (beginning in the late Triassic period) during the breakup of Pangaea, drifting farther north after the split. 
  • Gondwana also Gondwanaland, is the name given to an ancient supercontinent. 
  • It is believed to have sutured about 600 to 530 million years ago, joining East Gondwana to WestGondwana. 
  • Gondwana formed prior to Pangaea, and later became part of it.

Which of the following names is not applicable to the earth?

geography the earth and the graticule general idea about earth space around the earth is the earth round?

  1. Living Planet

  2. Blue Planet

  3. Unique Planet

  4. Mean Planet

Show answer
Correct Option: D
Explanation:
  • Planet Earth has been called the "Blue Planet" due to the abundant water on its surface. 
  • Here on Earth, we take liquid water for granted; after all, our bodies are mostly made of water.
  • However, liquid water is a rare commodity in our solar system.
