Answer:
The water cycle is the journey water takes as it moves from the land to the sky and back again. It follows a cycle of evaporation, condensation, precipitation and collection.
Explanation:
The water cycle
Water on Earth is constantly moving. It is recycled over and over again. This recycling process is called the water cycle.
1. Water evaporates into the air
The sun heats up water on land, in rivers, lakes and seas and turns it into water vapour. The water vapour rises into the air.
2. Water vapour condenses into clouds
Water vapour in the air cools down and changes back into tiny drops of liquid water, forming clouds.
3. Water falls as precipitation
The clouds get heavy and water falls back to the ground in the form of rain or snow.
4. Water returns to the sea
Rain water runs over the land and collects in lakes or rivers, which take it back to the sea. The cycle starts all over again.
Answer:
Countries trade with each other when, on their own, they do not have the resources, or capacity to satisfy their own needs and wants. By developing and exploiting their domestic scarce resources, countries can produce a surplus, and trade this for the resources they need.
Following are the techniques or methods or approaches we can say that were used by the scientists to determine the geologic age:
1. Relative age dating
2. Absolute age dating.
3. Radiation measurement.
4. Stratigraphic superposition.
5. The fossil record.
The scientists used the method of relative dating to divide Earth's past in different chunks of time when alike organisms were on Earth. After that, to discover the actual number of years ago that events occurred, the scientists used the method of absolute dating.
