The two sources of new materials involved in geologic processes are

Magma

Soil

Erosion products

Deltas

Magma and erosion products

The correct answer is option A and C i. e. Magma and erosion products

The magma is considered as a new product as it is formed from the lava that flows out of the volcano and is a new material produced periodically while the erosion products may not be produced at a particular place but since they are being carried away from some distant area they are new for the area where they are carried to.
