Which mountain range was form due to collision of Indian and Asian plate?

• A.

Himalyan

• B.

Hindu kush

• C.

Karakoram

• D.

Suleiman

A. Himalyan
Explanation
The Himalayan mountain range was formed due to the collision of the Indian and Asian tectonic plates. This collision resulted in the upliftment of the Earth's crust, creating the highest mountain range in the world. The Himalayas stretch across several countries including India, Nepal, Bhutan, and Tibet, and are known for their majestic peaks, including Mount Everest. The collision of these two plates continues to this day, causing the Himalayas to grow taller each year.

Which is the hottest layer of Earth?

• A.

Upper mantel

• B.

Lower mantel

• C.

Core

• D.

Crust

C. Core
Explanation
The core is the hottest layer of the Earth. It is composed of two parts, the outer core and the inner core. The outer core is made of liquid iron and nickel, while the inner core is solid due to the immense pressure. The temperature in the core can reach up to 5700 degrees Celsius, making it the hottest layer. The heat in the core is generated by the radioactive decay of elements and leftover heat from the formation of the Earth.

How many types of rocks are there?

• A.

Five

• B.

Two

• C.

Four

• D.

Three

D. Three
Explanation
There are three types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks are formed from cooled magma or lava, sedimentary rocks are formed from the accumulation and compression of sediments, and metamorphic rocks are formed from the transformation of existing rocks under high pressure and temperature.

How a river delta is formed?

• A.

Due to heavy rainfall

• B.

Due to soil erosion

• C.

Due to deposition of soil and clay

• D.

Due to landsliding

C. Due to deposition of soil and clay
Explanation
A river delta is formed due to the deposition of soil and clay. As a river flows towards its mouth, it carries sediment, such as soil and clay, along with it. When the river reaches a body of water, such as a lake or an ocean, the velocity of the water decreases, causing the sediment to settle and accumulate. Over time, this deposition builds up and forms a delta, which is a landform that resembles a fan or a triangle. The deposition of soil and clay is a gradual process that contributes to the formation and growth of river deltas.

What does a bend or a curve in a river called?

• A.

Source

• B.

Meander

• C.

Delta

• D.

Mouth

B. Meander
Explanation
A bend or curve in a river is called a meander. Meanders are formed when the river's flow erodes the outer bank and deposits sediment on the inner bank, causing the river to change its course. Over time, these bends become more pronounced, creating the characteristic winding shape of a meandering river.

Who proposed the theory of a super continent called Pangea?

• A.

Alfred Wegener

• B.

Pierre Jules Cesar

• C.

Sir William

• D.

Louis Jacques

A. Alfred Wegener
Explanation
Alfred Wegener proposed the theory of a supercontinent called Pangea. This theory suggests that all the continents were once connected as one large landmass, which eventually split apart and drifted to their current positions. Wegener developed this idea in the early 20th century based on the observation of similarities in the coastlines, geological formations, and fossil records of different continents. He proposed that the continents had moved over time due to the process of continental drift, which was later supported by the discovery of plate tectonics.

Which type of rocks form the oceanic crust?

• A.

Sedimentary

• B.

Igneous

• C.

Sandstone

• D.

MetamorpHic

B. Igneous
Explanation
Igneous rocks form the oceanic crust because they are formed from the solidification of molten magma or lava. As magma rises to the surface and cools, it solidifies to form igneous rocks. This process is common in the oceanic crust, where volcanic activity and the movement of tectonic plates create opportunities for magma to reach the surface and solidify. Sedimentary, sandstone, and metamorphic rocks are not typically found in the oceanic crust as they are formed through different processes such as the accumulation of sediment, compression, and metamorphism.

Which type of minerals is used to make wires,coins and medals?

• A.

SulpHer

• B.

Gypsum

• C.

Copper

• D.

Chromite

C. Copper
Explanation
Copper is used to make wires, coins, and medals because it is an excellent conductor of electricity and has good corrosion resistance. It is also a malleable metal, which means it can be easily shaped into wires and coins. Additionally, copper has a pleasing appearance and is often used for decorative purposes in medals and coins.

Where is the source of Indus river located?

• A.

Karakoram range

• B.

Potohar plateau

• C.

Himalyan range

• D.

Tibetan plateau

D. Tibetan plateau
Explanation
The source of the Indus River is located in the Tibetan plateau. The Tibetan plateau is a vast elevated region in Asia, known as the "Roof of the World." It is located in western China and extends into parts of India, Nepal, and Bhutan. The Indus River originates from a glacier called the Bokhar Chu, which is located in the southwestern part of the Tibetan plateau. From there, it flows through the Karakoram range, Potohar plateau, and eventually into the Arabian Sea.

What is the length of Indus river

• A.

1000km

• B.

4000km

• C.

3200km

• D.

5200km

C. 3200km
Explanation
The correct answer is 3200km because the length of the Indus river is measured to be 3200 kilometers.
