Unit 5 The Natural World

Explanation
The correct answer is "mountain" because mountains are known for their height. They are large landforms that rise above the surrounding land and often have steep slopes. Climbing a mountain requires physical strength, endurance, and proper equipment. Therefore, a mountain fits the description of being tall and is the most appropriate choice among the given options.

Explanation
A volcano is like a mountain because it has a similar shape and structure. However, unlike a regular mountain, a volcano is very hot and dangerous due to the presence of molten lava and the potential for eruptions. Volcanoes can release ash, gases, and lava, causing destruction and posing a threat to nearby areas. Therefore, the comparison between a volcano and a mountain highlights the extreme conditions and hazards associated with volcanoes.

Explanation
An island is a landmass that is surrounded by water, either in an ocean or a lake. It is separate from the mainland and can only be accessed by boat. Therefore, the correct answer is island.

Explanation
A lake is a body of water that is smaller than the ocean. People often go sailing on lakes, enjoying recreational activities such as boating and fishing. Lakes are typically surrounded by land and can vary in size, ranging from small ponds to large bodies of water.

Explanation
A river is a body of water that flows across land. The Amazon is a specific example of a river.

Explanation
The Amazon is known for being hot and having a lot of trees, which aligns with the characteristics of a jungle. The Amazon rainforest, located in South America, is the largest tropical rainforest in the world and is home to a diverse range of plant and animal species.

Explanation
A forest is a natural habitat that consists of a large number of trees. It can be found in various regions around the world and can experience different climates, including both cold and hot temperatures. Therefore, the given answer "forest" is the most suitable option as it aligns with the description provided in the question.

Explanation
The given question mentions that it is very hot and there is sand in the ______. The correct answer is desert. This is because deserts are known for their extreme heat and vast stretches of sandy terrain. Volcanoes are not typically associated with sand, and waterfalls are not typically hot or sandy. Therefore, the most logical answer is desert.

Explanation
A cave is a natural underground chamber or passageway that is typically formed by the erosion of rock. It is often found under the ground or in a mountain. Bats are known to inhabit caves, making it a suitable habitat for them.

Explanation
Water that falls from a mountain or higher land is known as a waterfall. Waterfalls are formed when rivers or streams flow over a steep cliff or rock formation, creating a dramatic cascade of water. The force of gravity causes the water to plunge downwards, creating a beautiful and mesmerizing sight. Waterfalls are often found in mountainous regions and are a popular tourist attraction due to their natural beauty and power.
