water cycle is cycle and it's helps in our fitteness
Answer:
1.The water cycle , also known as the hydrologic cycle, describes the continuous movement of water as it makes a circuit from the oceans to the atmosphere to the Earth and on again. Most of Earth's water is in the oceans. The sun, which drives the water cycle, heats water in the oceans.
2.Earth is rightfully called a water-world: far more than half of our planet is covered in water. ... That's because the ocean covers 71 percent of Earth's surface. The ocean is accordingly a major component of the hydrosphere, and it plays an important role in Earth's water cycle.
3.Mountains, hills, plateaus, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins.
4.Parent rock, also referred to as substratum, refers to the original rock from which something else was formed. It is mainly used in the context of soil formation where the parent rock normally has a large influence on the nature of the resulting soil.
