-
Shield
-
Disk
-
Pancake
-
Rosette
D
Correct answer
Explanation

-
Shield
-
Disk
-
Pancake
-
Flowstone
D
Correct answer

-
Shield
-
Disk
-
Pancake
-
Helictite
D
Correct answer
Explanation
Helictites are known for their delicate and intricate structure and often grow in twisted or spiral shapes, sometimes horizontally.
Which of the following is NOT a potential implication of ice chemistry in geochemistry?
-
The formation of mineral deposits
-
The origin of life on Earth
-
The role of ice in shaping landscapes
-
The study of ancient climates
B
Correct answer
Explanation
While ice chemistry can provide insights into the formation of mineral deposits, the role of ice in shaping landscapes, and the study of ancient climates, the origin of life on Earth is not directly related to ice chemistry.
What is the primary composition of most meteorites?
-
Iron and Nickel
-
Rock and Minerals
-
Ice and Gas
-
Organic Compounds
A
Correct answer
Explanation
Most meteorites are composed primarily of iron and nickel, forming a type of meteorite known as an iron meteorite.

The Deccan Traps region in India is home to which type of rock formation?
-
Basalt
-
Granite
-
Sandstone
-
Limestone
A

The Western Ghats, a prominent mountain range in India, are primarily composed of which type of rock?
-
Granite
-
Basalt
-
Sandstone
-
Limestone
A
Correct answer
Explanation

Which of the following is not a type of rock?
-
Igneous rock
-
Sedimentary rock
-
Metamorphic rock
-
Fossil
D
Correct answer
Explanation

What is the primary role of lichens in the rock cycle?
-
Weathering of rocks
-
Formation of rocks
-
Erosion of rocks
-
None of the above
A
Correct answer
Explanation
Lichens play a crucial role in the rock cycle by weathering rocks through the release of organic acids and other compounds. This process helps break down rocks into smaller particles, making them more susceptible to erosion and further weathering.
Which type of island is formed when sediment, coral, or other organic material accumulates on top of an underwater feature?
-
Continental Island
-
Volcanic Island
-
Barrier Island
-
Atoll
C
Correct answer
Explanation
Barrier islands are formed by the accumulation of sediment, coral, or other organic material on top of an underwater feature, typically parallel to the coastline.
What is the primary geological formation used for storing CO2 in CCS projects?
-
Aquifers
-
Depleted oil and gas reservoirs
-
Basalt formations
-
Salt caverns
B
Correct answer
Explanation
Depleted oil and gas reservoirs are commonly used for storing CO2 in CCS projects because they have existing infrastructure and geological characteristics suitable for long-term storage.
Which of the following is NOT a common type of reservoir rock?
-
Sandstone
-
Limestone
-
Shale
-
Granite
D
Correct answer
Explanation
