Landforms And Waterbodies: Trivia Quiz!

Explanation
A peninsula is a landform that is surrounded by water on three sides. It is connected to the mainland on one side and has water on the remaining three sides. This makes it different from an island, which is completely surrounded by water, and a lake, which is an inland body of water. A desert does not have water surrounding it on three sides. Therefore, the correct answer is peninsula.

Explanation
Landforms are the correct answer because they refer to the large shapes of land on the Earth's surface. This term encompasses various features such as mountains, valleys, plains, plateaus, and more. Landforms are the result of geological processes like erosion, deposition, and tectonic activity, and they play a significant role in shaping the Earth's surface and influencing ecosystems and human activities.

Explanation
An island is a landmass that is completely surrounded by water. It is separate from the mainland and can be found in oceans, seas, lakes, or rivers. Islands can vary in size, from small islets to large land masses like Australia or Greenland. The presence of water on all sides distinguishes an island from other land formations such as valleys, rivers, or oceans.

Explanation
A large stream of water that flows into a lake or the ocean is a river. Rivers are natural watercourses that carry water from higher elevations to lower elevations, eventually emptying into larger bodies of water such as lakes or oceans. They play a crucial role in the water cycle and serve as habitats for various plants and animals.

Explanation
An ocean is a vast body of saltwater that covers a significant portion of the Earth's surface. It is much larger than a sea and is not connected to any specific landmass. Oceans are characterized by their immense size, depth, and the variety of marine life they support. They play a crucial role in regulating the Earth's climate and are essential for maintaining the planet's overall balance.

Explanation
A valley is a low land that is located between two mountains or hills. It is typically formed by erosion or the movement of glaciers. Valleys are characterized by their U-shaped or V-shaped appearance, with steep sides and a flat or gently sloping floor. They often contain rivers or streams that flow through them. Valleys are important geographical features as they provide fertile land for agriculture and are often inhabited by human settlements.

Explanation
The given answer correctly states that an ocean has salt water, while a river has fresh water. This is a key difference between the two bodies of water. Oceans are vast bodies of salt water, covering a large part of the Earth's surface, while rivers are freshwater streams that flow towards larger bodies of water. This difference in salinity is due to various factors such as the presence of marine life, evaporation, and geological processes.

Explanation
Lakes are not formed by saltwater. Lakes are bodies of water that are typically formed by various natural processes such as tectonic activity, volcanic activity, glacial activity, or the filling of a basin. Saltwater bodies of water such as seas and oceans are not considered lakes. Therefore, the statement that lakes are formed by saltwater is incorrect.
