A wide sloping deposit of sediment formed where a stream leaves a mountain range is called an alluvial fan. An alluvial fan is the deposition of sediment on a landform like mountain. It forms as an open fan or cone of sediment. The sediments are left by natural drainage system like river on the landform.

There are two types of alluvial fans.

1. Debris dominated: These includes viscous mixture of water, mud, gravel along with woody debris. This transfer large boulders of landform soil.

2. Floodwater dominated: Water will spill in the alluvial fan in the form of thin sheets. This can transfer fine particles of landform soil.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
