The body of a land plant is often covered with a waxy to prevent dessication. 1) gametangium 2) cuticle
3) sporangium 4) thallus

Cuticle refers to the waxy coating which protects the land plants from desiccation.  

Option 2

Explanation:

When the plants are present on the land, during drought-like conditions, they become victims of desiccation. To overcome this adverse condition, plants surviving on land have a special protective waxy covering called cuticle.

The cuticle covers all the parts of the plants such as leaves, stem, young shoots, etc and acts as a protective coat. It prevents the transpiration process in the land plant through which water from the plant evaporates and prevents them from desiccation.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.
