Answer -1 The cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration. Question -2 What is a transpiration? Answer -2 Transpiration is the process by which plants return water to the atmosphere. After absorbing water from the ground, plants release water through their leaves Question -3 What is water vapour? Answer -3Water vapour is the gas phase of water. When the liquid is turned into gas it is formed. Question -4 What is precipitation? Answer -4. The liquid and solid water particles that fall from clouds and reach the ground are known as precipitation. These particles include drizzle, rain, snow, hail. Question -5 What is evaporation? Answer -5. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or steam.

Question -7 What are permeable rocks? Answer -7 Permeable rocks are rocks that allow water to passes through/into them. Examples are soil and sand. Question -8 What are non-permeable rocks? Answer -8 Non- permeable rocks are rocks that do not allow water to passes through/into them. Examples are basalt and granite. Question -9 What are glaciers? Answer -9 A glacier is a huge mass of ice that moves slowly over land. The term “glacier” comes from the French word glace (glah-SAY), which means ice. Question -10 What is erosion? Answer -10 Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. It is the breakdown of the continents and the land around you.

A meander forms when moving water in a stream erodes the outer banks and widens its valley, and the inner part of the river has less energy and deposits silt. Question -15 What is an ox-bow lake? Answer -15 An oxbow lake is a U-shaped body of water that forms when a wide meander from the main stem of a river is cut off, creating a freestanding body of water. Question -16What is an estuary?

It runs for over 1,232 km (766 mi) from its source in the in the Swiss Alps (in Switzerland), issuing from the Rheinwaldhorn Glacier 3,353m above sea level. The River Rhine is the major source of hydro-electricity. The Rhine is also linked to the other main rivers of Europe by canals, so that cargoes from the Rhine ports or overseas can be sent all over mainland Europe. Many large settlements have developed on the banks of the River Rhine. The Rhine flows through six countries -Switzerland, Principality of Liechtenstein, Austria, Germany, France and the Netherlands before flowing into the North Sea at Rotterdam. As the Rhine enters Germany it becomes the border between Germany and France. Many years ago, the Rhine was considered as one of the most polluted rivers in Europe. Many tourists each year go on Rhine River cruises, travelling by river barge. River Nile The River Nile is about 6,670 km (4,160 miles) in length and is the longest river in Africa and in the world. Although it is generally associated with Egypt, only 22% of the Nile’s course runs through Egypt.In Egypt, the River Nile creates a fertile green valley across the desert. It was by the banks of the river that one of the oldest civilizations in the world began. The ancient Egyptians lived and farmed along the Nile, using the soil to produce food for themselves and their animals. Around 40 million people (half of Egypt’s population) live in the Nile Delta region. The River Nile is in Africa. It originates in Burundi, south of the equator, and flows northward through northeastern Africa, eventually flowing through Egypt and finally draining into the Mediterranean Sea. The River Nile is in Africa. It originates in Burundi, south of the equator, and flows northward through north eastern Africa, eventually flowing through Egypt and finally draining into the Mediterranean Sea. The Aswan High Dam was built in 1970 to help regulate flooding of the Nile River. Before the Aswan Dam was built, years that featured high levels of water could wipe out crops while years of low level water could produce famines and drought. The dam helps control these water levels. Royal Buckingham International School www.royalbuckinghaminstitution.com
