Answer: I and II only
Explanation:
Cover crops are planted in order to protect the soil when the main cash crop is not being planted which means that they are not planted to be harvested and can be planted after the cash crop is harvested.
The two main purposes of cash crops are to protect the soil from erosion and to improve soil fertility. Their presence reduces surface runoff of soil when it rains and slows down rain before it hits the ground at force and splits soil.
Some cover crops are planted to improve soil fertility because they improve the level of nutrients in the soil and they can also be ploughed before they mature causing them to decay and add organic matter to the soil.

Sclerophyll forest are typically Australian vegetation type having ( typically eucalyptus, wattles and banksias) with hard, short and often spiky leaves which is a condition closely associated with low soil fertility ( rather than rain forest and soil moisture)
Yes they are considered documents
Layers that are less dense, such as the crust<span>, float on layers</span> that are denser, such as the mantle. Both oceanic crust and continental crust are less thick than the mantle, but the marine crust is denser than continental crust. This is partly why the continents are at a higher elevation than the ocean floor.
