Earth is made up of...
Correct Answer
C. Land and Water
Explanation
Earth is made up of both land and water. The Earth's surface is composed of landmasses, including continents and islands, as well as large bodies of water, such as oceans, seas, and lakes. The land provides a solid base for the existence of various ecosystems and supports the growth of vegetation. On the other hand, water covers about 71% of the Earth's surface and is essential for the survival of all living organisms. It plays a crucial role in regulating the climate, providing habitats for marine life, and serving as a vital resource for human activities.

Correct Answer
C. Liquid water
Explanation
Earth has life on it because it has liquid water. Liquid water is essential for the existence of life as we know it. It provides a medium for chemical reactions to occur, acts as a solvent for essential molecules, and regulates temperature. Water also supports various ecosystems and is crucial for the survival of many organisms. Without liquid water, it would be extremely challenging for life to thrive on Earth.
4.
Many land forms were formed by...
Correct Answer
D. Glaciers
Explanation
Glaciers are a correct answer because they have played a significant role in shaping the Earth's landforms. As massive bodies of ice, glaciers move slowly over time, eroding the land beneath them and carving out valleys and basins. They also deposit sediment and rocks as they melt, forming moraines and creating features like drumlins and eskers. Glaciers have been instrumental in forming various landforms such as fjords, cirques, and U-shaped valleys. Their powerful erosive capabilities have left a lasting impact on the Earth's surface, making them a key factor in the formation of many landforms.
