Answer 2

(iv) Volcanic ash, remains of plants and animals, abyssal plains

Explanation:

1. Marine deposits are the deposits found on the floor of larger water bodies including seas and oceans.

2. The materials flown into the sea or ocean from the rivers and other small water bodies are called deposits since these materials are not soluble in water.

3. They settle down on the floor forming a blanket of deposits. This blanket is fertile and provides nutrients required for vegetation growth. This results in the development of abyssal plains.
