Few plants can survive in a desert because too much leaching occurs there are many herbivores the sun is too hot the climate is too dry

It is dry in deserts and hot too. There are special kinds of plants that grow in desserts means they have specialized characteristics which help them beat the dry and hot weather.

Succulent plants such as cacti, aloes, agaves have ability to store water in their leaves and stems which have thick and hard outer layer to avoid evaporation of water.

These plants have small spicules on their outer surface which protects them from animals as well.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.

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.
