A sea is great body of water, usually salty, that covers the earth broadly. It is a connected body of salt water that covers 70% of the earth.
The ocean on the other hand, is a large area of water in between continents. They are very big and they join smaller seas together. Together, the oceans are like one "ocean", since all the "oceans" are joined
The North East coast of Canada remains icebound during winter
because of forcing of the air. As the North East coast of Canada is
located near to Northern poles and is nearer to sea hence the ports of
eastern coast of Canada freezes and the temperature in that area
becomes less than zero degree during the winter time.
Ocean currents are horizontal continuous flow of water from one place
to other . There are two types of ocean currents warm and cold flowing
along the coastline which will have an impact on climate. Thus these
waters are cold and tend to freeze up the ports early in winters.

Explanation:
- Mechanical weathering involves the breakdown of the rocks into small pieces by the external support such as pressure whereas Chemical weathering involves the breakdown of the rocks takes place by the chemical process.
- Mechanical weathering is a physical change that is caused by the movement of wind and water whereas chemical weathering takes place when the chemicals present in the air or water get mixed with minerals or rocks.
- Mechanical weathering involves:
Abrasion, freezing, thawing, exfoliation.
- Whereas Chemical weathering involves:
dissolution, oxidation, carbonation, hydrolysis.
The Sun is a main - sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second.
