* The world’s largest river lies in South America continent.

* South America lies completely in the Southern Hemisphere.

* It is surrounded by two oceans namely, Pacific Ocean and Atlantic Ocean. The world’s longest mountain range, i.e., the Andes, runs through its length from north to south.

* The continent contains the world’s largest river, Amazon.

* Africa contains the longest river, i.e., Nile.

* Mehrgarh site of Harappan civilization is located near Bolan Pass.

* Mehrgarh is one of the oldest sites of the Indus Valley Civilization located in the Balochistan region of Pakistan.

* The houses were built using mud bricks and some were multi-roomed. The houses also had storage areas and courtyards.

* Evidence of farming and herding is found here.

Hence, option D is the right answer.

* Sugarcane is a tropical crop that takes around 10 to 12 months to mature and be ready for harvest.

* Sugarcane is a tall, perennial grass that is grown in tropical and subtropical regions.

* It requires warm temperatures, lots of sunshine, and ample rainfall to grow successfully.

* Sugarcane is typically propagated from cuttings of the stalks of mature plants, which are planted in furrows or trenches in the soil.

Hence, option A is the correct answer.

* The Deccan plateau is a large plateau that covers most of South India. It is situated to the south of the Narmada River.

* The Narmada River is one of the major rivers of central India and flows westward through the states of Madhya Pradesh and Maharashtra before emptying into the Arabian Sea.

* The Deccan plateau is bordered by several mountain ranges, including the Western Ghats and the Eastern Ghats. The plateau is known for its extensive lava flows, which have given rise to a unique landscape of flat-topped hills and deep valleys.

* The Deccan plateau is home to a rich diversity of flora and fauna, including several species that are endemic to the region.

Hence, option A is the correct answer.

India is located in South Asia and shares land borders with several countries in the region. These countries are :-

* Pakistan - India shares a land border of approximately 3,323 km with Pakistan.

* China - India shares a land border of approximately 3,488 km with China.

* Nepal - India shares a land border of approximately 1,751 km with Nepal.

* Bhutan - India shares a land border of approximately 699 km with Bhutan.

* Bangladesh - India shares a land border of approximately 4,096 km with Bangladesh.

* Myanmar - India shares a land border of approximately 1,643 km with Myanmar.

* Afghanistan - India shares a small land border of approximately 106 km with Afghanistan.

Hence, option A is the correct answer.

* Sedimentary rocks are one of the three major types of rocks found on Earth, along with igneous and metamorphic rocks.

* They are formed through the accumulation and solidification of sediment, which is made up of fragments of rocks, minerals, shells, and other organic material.

* Sandstone is a type of sedimentary rock that is composed primarily of sand-sized grains of mineral, rock, or organic material.

* These grains are usually cemented together by silica, calcium carbonate, or iron oxide, which gives the rock its characteristic texture and appearance.

Hence, option A is the correct answer.

* The Alps are a young fold mountain. Fold mountains are mountains that are formed through the process of folding, which occurs when two tectonic plates collide, and the pressure causes the rocks to buckle and fold.

* They are characterized by long, linear ridges with steep slopes on either side.

* The age of a fold mountain depends on when it was formed and how long it has been exposed to the forces of erosion.

* Young fold mountains are those that have been formed relatively recently and have not yet been significantly eroded.

Hence, option A is the correct answer.

* The Coriolis Force is a physical phenomenon that affects objects moving on the surface of a rotating planet, such as the Earth. It is caused by the rotation of the planet itself.

* To understand the Coriolis Force, imagine a person standing at the equator and throwing a ball due north.

* To the person, it appears that the ball is moving straight toward the north pole. However, from the perspective of an observer looking down on the Earth from space, the ball is actually traveling along a curved path that is rotating along with the planet.

* This is because the Earth is rotating from west to east, and the ball inherits some of this eastward motion as it moves north.

Hence, option A is the correct answer.

* The minimum temperature of the day occurs generally in the early morning.

* This is because during the night, the earth's surface cools down due to the loss of heat radiation to the atmosphere.

* As a result, the air near the ground also cools down and becomes denser, causing it to sink.

* This sinking air reduces the mixing of the lower atmosphere with the upper atmosphere, which leads to a buildup of cold air near the surface.

Hence, option D is the correct answer.

* Push and pull factors are associated with migration. Push factors are those that encourage people to leave their current place of residence, such as poverty, political instability, lack of opportunities, and environmental issues.

* Pull factors are those that attract people to a new place, such as better job opportunities, political stability, and a higher standard of living. Both push and pull factors can influence migration patterns.

* Migration is the movement of people from one place to another, typically for better living conditions or job opportunities. Migration can be internal (within a country) or international (across borders).

* It can be voluntary or forced, and can occur due to a variety of reasons, such as economic, social, political, or environmental factors.

Hence, option A is the correct answer.
