Hardest Trivia Quiz On Geography For 10th Grade - Quiz

2.

What type of weathering is also known as mechanical weathering?
- Physical weathering
- Chemical weathering
- Thermal weathering
- Isolation weathering
Correct Answer

A. Physical weathering

Explanation

Physical weathering, also known as mechanical weathering, refers to the breakdown of rocks into smaller pieces without changing their chemical composition. It is caused by physical forces such as temperature changes, freeze-thaw cycles, and abrasion. These forces weaken the rocks and cause them to crack, break, or disintegrate into smaller fragments. Some common examples of physical weathering include the freeze-thaw action of water in cracks, wind erosion, and the impact of waves on coastal rocks.

What type of weathering is also known as thermal stress weathering?
- Mechanical weathering
- Chemical weathering
- Isolation weathering
- Frost weathering
Correct Answer

A. Isolation weathering
4.

Which of these is not an agent of denudation?
- Ice
- Waves
- Wind
- Weather
Correct Answer

A. Weather

Explanation

Weather is not an agent of denudation because it refers to the conditions of the atmosphere, such as temperature, precipitation, and humidity. While weather can indirectly contribute to denudation processes by influencing other agents like wind and water, it is not a direct agent itself. Denudation refers to the wearing away and removal of the Earth's surface materials, which is primarily caused by agents like ice, waves, and wind through processes like erosion and weathering.

5.

What is the primary process in physical weathering?
- Denudation
- Rotation
- Revolution
- Abrasion
Correct Answer

A. Abrasion

Explanation

Abrasion is the primary process in physical weathering. This process involves the wearing down and breaking apart of rocks and minerals through the mechanical action of friction, caused by the movement of water, wind, ice, or other forces. It occurs when particles or debris continuously rub against the surface of rocks, causing them to chip, crack, and eventually disintegrate. Abrasion is a common process in areas with high wind or water flow, such as deserts or riverbeds, where the constant movement of particles can erode and shape the landscape over time.

6.

Which of these does not cause physical weathering?
- Pressure
- Frost
- Man
- Temperature
Correct Answer

A. Man

Explanation

Man does not cause physical weathering because physical weathering refers to the breakdown of rocks and minerals through natural processes such as temperature changes, frost action, and pressure. While human activities can contribute to weathering through processes like chemical weathering or erosion, they are not considered as causes of physical weathering. Therefore, man is the correct answer as it does not directly cause physical weathering.

Rate this question:
7.

Which of these is not a process of chemical weathering?
- Dissolution
- Carbonation
- Oxidation
- Abrasion
Correct Answer

A. Abrasion

Explanation

Abrasion is not a process of chemical weathering because it involves the physical wearing down of rocks and minerals through friction and impact, rather than chemical reactions. Chemical weathering processes, on the other hand, involve the alteration of rock and mineral composition through chemical reactions. Dissolution, carbonation, and oxidation are all examples of chemical weathering processes, where minerals are dissolved, carbon dioxide reacts with water to form carbonic acid, and minerals react with oxygen respectively.

Rate this question:
8.

Which of these increase chemical weathering rates in rocks?
- Algae
- Ants
- Lichens
- Fungi
Correct Answer

A. Lichens

Explanation

Lichens increase chemical weathering rates in rocks. Lichens are a symbiotic relationship between fungi and algae or cyanobacteria. They produce organic acids that can dissolve minerals in rocks, leading to their weathering. This process is known as biological weathering. Algae, ants, and fungi do not have the same effect on chemical weathering rates as lichens do.

9.

What type of rock is obtained from pre-existing rocks?
- Sedimentary rocks
- Igneous rocks
- Metamorphic rocks
- Fold rocks
Correct Answer

A. Metamorphic rocks

Explanation

Metamorphic rocks are formed from pre-existing rocks that have undergone intense heat and pressure, causing the minerals and textures to change. This process occurs deep within the Earth's crust and can be influenced by tectonic activity or contact with magma. Sedimentary rocks are formed from the accumulation and hardening of sediments, while igneous rocks are formed from the solidification of molten material. Fold rocks do not exist as a distinct rock type and are likely a misinterpretation or incomplete option. Therefore, the correct answer is metamorphic rocks.

What is the average pH of rainfall in an unpolluted environment?
- 3.4
- 5.6
- 1.8
- 6.6
Correct Answer

A. 5.6

Explanation

The average pH of rainfall in an unpolluted environment is 5.6. pH is a measure of the acidity or alkalinity of a substance, with values below 7 indicating acidity and values above 7 indicating alkalinity. A pH of 5.6 suggests that the rainfall is slightly acidic, which is normal for unpolluted environments.
