QUESTION 20
What is the difference between an ocean and a sea?
Seas are generally smaller than an ocean and tend to be partially enclosed by land or large, inland, saline water bodies.
An ocean is a vast body of water encompassing 70% of Earth, whereas a sea refers specifically to a large, inland, saline body of water.
The term sea is used to describe the global, interconnected water body covering 70% of Earth's surface, whereas oceans refer to the individual basins within this global sea.
There is no difference, just a different term for the same physical feature.

tsunami.
Explanation / Answer
1) tsunami.
An earthquake, a submarine landslide, or a volcanic eruption cause displacement of large volume of water which results in a tsunami.
2) surfaces of concentrated pebbles and gravels.
Note : Desert pavement refers to surfaces of concentrated pebbles and gravels which are formed by removing small particles like sand, dust by wind and rain which leaves the bigger particles behind.The bigger particles form a desert pavement with the help of factors like rain, wind ,gravitational force etc.
