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.

-Hot desert biome
Explanation;
Hot Desert is characterized by very little rainfall or a lot of rain in a very short period. The soils are often salty because minerals do not get washed away. Thus, the climate is characterized by a very little precipitation.
-Plant adaptations: There are few plant species. these plants are adapted to resist drought and store water. For example; Spiny cacti that have thick, fleshy stems that conserve water are common. Their roots extend metres away from the plant to absorb water. Other plants have small, thick, waxy leaves that also store water. Many plants have spines or produce chemicals that protect them from being eaten.
