Chapter 30, Problem 13TE

To determine

The reason that the melting of polar ice caps is more concern than there is melting iceberg.

Answer to Problem 13TE

The melting of polar ice caps is more concerned because polar ice caps' melting generates icebergs in the ocean. These icebergs can damage the floating ships, and increase the water level in the ocean, which can bring flooding in the coastal area.

Explanation of Solution

The formation of polar ice caps occurs from freezing of the freshwater and accumulation of snow over a large period. When these ice caps melt and break due to the high temperature, icebergs formation takes place in the ocean. So these icebergs formed in the ocean from the melting of polar ice caps can damage the ships that float in the ocean form transportation.

The other reason for the melting of polar ice is the matter of concerns is that melting increases the amount of water in the ocean and due to this, base sea level increases. This increased sea level can bring the condition of a flood near the low coastal area.

Conclusion:

Therefore, the melting of polar ice caps is more concerned because polar ice caps' melting generates icebergs in the ocean. These icebergs can damage the floating ships, and increase the water level in the ocean, which can bring flooding in the coastal area.
