Answer: Bays are thought to be formed by plate tectonic activity and erosion of coastline.
Explanation:
A body of water irregularly surrounded by land is known as a bay. And it is quite different from a gulf.
A bay is formed this way:
• when there is an erosion of the coastline into a large body of water. E.g Guanabara Bay.
• in pre-historic era, during active plate tectonic activity where continents drifts together and as they rift apart, there is the fomation of many large bays. E.g Bengal Bay.

Mountains are formed by the movements of the tectonic plates and Earth's. Movements deep beneath the Earth's surface cause a variety of reactions, and the results in different types of mountains. Mountains can form as a result of the volcanic activity, the collision of 2 tectonic plates or a movement along a fault line.
