Test: The World around Us - Grade 2 MCQ

Neil Armstrong was the first person to set foot on the moon during the Apollo 11 mission in 1969. His famous words, "That's one small step for [a] man, one giant leap for mankind," mark a significant moment in human history.

There are eight recognized planets in our solar system, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Each planet has its unique characteristics and orbits the sun.

A globe is a three-dimensional model of the Earth that represents geographical features accurately. It helps in understanding the Earth's shape, continents, and oceans, providing a more realistic view than flat maps.

The sun is indeed a star and serves as the central body of our solar system. It generates energy through nuclear fusion and is crucial for sustaining life on Earth.

When the snow on mountains melts, it typically forms streams that can combine to create rivers. This process is vital for the water cycle and supports ecosystems downstream.

The moon cannot support life as we know it primarily because it lacks an atmosphere, which means there is no air to breathe and no liquid water available. These two elements are essential for sustaining life.

A valley is defined as a low area of land that lies between hills or mountains. Valleys are often fertile and suitable for agriculture due to the accumulation of nutrients from surrounding elevations.

An island is defined as a piece of land that is completely surrounded by water. This geographic feature can vary significantly in size, with some of the largest islands, like Australia, being classified as continents.

Mars is commonly referred to as the "Red Planet" due to its reddish appearance, which comes from iron oxide (rust) on its surface. This distinctive color has made it a subject of interest in both astronomy and popular culture.

When multiple streams combine, they form a river. Rivers can vary in size and are crucial for transporting water, supporting wildlife, and serving as resources for human use.

The Earth is described as being round, similar to the shape of an orange, although it is slightly flat at the top and bottom. This shape is an important aspect of understanding Earth's geography and its movement in space.

The Tibetan Plateau is known as the highest and largest plateau in the world, often referred to as "the Roof of the World." Its unique elevation and flatness contribute to its significance in climate and ecology in the region.

Hills are referred to as highlands because they are elevated areas of land. They are generally less steep than mountains and can be rocky, providing unique ecosystems and habitats for various species.

An ocean is not classified as a landform; it is a large body of water. Landforms refer specifically to the physical features of the Earth's surface, such as mountains, valleys, and deserts.

Rivers are a type of water body that flows continuously, often feeding into larger bodies of water such as lakes or oceans. They are essential for ecosystems and human civilizations alike.

Approximately three-fourths of the Earth's surface is covered by water, which includes oceans, seas, lakes, and rivers. This vast amount of water plays a critical role in weather patterns and climate.

A plateau is characterized as a high area of land that is flat on top, resembling a table. This unique structure can support diverse plant and animal life and is often found in various geographical regions.

A lake is a significant body of water surrounded by land. Lakes can be fresh or salty and play crucial roles in ecosystems by providing habitats for numerous species and recreational areas for humans.

The sun is the primary source of energy for the Earth, providing heat and light essential for life. This energy is harnessed in various ways, including through solar power technologies.

Deserts are characterized by very little rain, making them arid and often sandy or rocky. This harsh environment limits the types of plants and animals that can survive there, leading to unique adaptations for life.
