What is the main type of rock found in the Vindhya Range?
-
Granite
-
Sandstone
-
Limestone
-
Basalt
B
Correct answer
Explanation
The main type of rock found in the Vindhya Range is sandstone.
Which of these is a metamorphic rock commonly found in safari regions?
-
Granite
-
Limestone
-
Slate
-
Sandstone
C
Correct answer
Explanation
Slate is a metamorphic rock formed from the transformation of clay-rich sediments under heat and pressure. It is commonly found in safari regions, often exhibiting distinct layering and a smooth, fine-grained texture.
Which of these is a sedimentary rock commonly formed from the accumulation of organic matter?
-
Limestone
-
Sandstone
-
Coal
-
Slate
C
Correct answer
Explanation
Coal is a sedimentary rock formed from the accumulation and compaction of plant matter over millions of years. It is a valuable energy resource and is commonly found in safari regions.
What is the process by which molten rock cools and solidifies, forming igneous rocks?
-
Weathering
-
Erosion
-
Deposition
-
Crystallization
D
Correct answer
Explanation
Crystallization is the process by which molten rock cools and solidifies, forming igneous rocks. As the molten rock cools, minerals crystallize, forming the characteristic textures and compositions of igneous rocks.
Which of these is a type of sedimentary rock formed from the accumulation of sand-sized particles?
-
Limestone
-
Sandstone
-
Coal
-
Slate
B
Correct answer
Explanation
Sandstone is a sedimentary rock formed from the accumulation and compaction of sand-sized particles. It is a common rock type found in safari regions and can exhibit various colors and textures.
Which of these is a type of igneous rock formed from the rapid cooling of lava on the Earth's surface?
-
Granite
-
Basalt
-
Slate
-
Sandstone
B
Correct answer
Explanation
Basalt is a type of igneous rock formed from the rapid cooling of lava on the Earth's surface. It is a common rock type in safari regions, often forming extensive lava flows and volcanic formations.
Which of these is a type of sedimentary rock formed from the accumulation of calcium carbonate, often derived from marine organisms?
-
Limestone
-
Sandstone
-
Coal
-
Slate
A
Correct answer
Explanation
Limestone is a type of sedimentary rock formed from the accumulation of calcium carbonate, often derived from marine organisms. It is a common rock type in safari regions and can exhibit various colors and textures.
Which of these is a type of metamorphic rock formed from the transformation of limestone under heat and pressure?
