What is Terrestrial?
-It refers to things related to land.
-Land habitat
Which land habitats do you recognize?
* Desert
* Rain Forest
* Tundra
* Prairie
* Grassland
Desert
* is a landscape or region that receives an extremely low amount of precipitation, less than enough to support growth of most plants. *
Desert features
* Sand covers only about 20% of Earth's deserts. Most of the sand is in sand sheets and sand seas—vast regions of undulating dunes resembling ocean waves "frozen" in an instant of time

Five Forms of Desert:
1. Mountain and basin deserts
2. Hamada deserts
-which consist of plateau landforms
3. Regs
-which consist of rock pavements
4. Ergs
-which are formed by sand seas
5. Intermontane Basins

Flora
-Deserts have a reputation for supporting very little life, but in reality deserts often have high biodiversity.

Some desert flora include:
1. Shrubs
2. Prickly Pears
3. Desert Holly
4. Brittlebush.
Most desert plants are drought- or salt-tolerant, and are called xerophytes.

Fauna
Desert fauna include animals that remain hidden during daylight hours to control body temperature or to limit moisture needs.
Some fauna includes the kangaroo, rat, coyote, jack rabbit, and many lizards. These animals adapted to live in deserts are called xerocoles.

Human life in deserts
A desert is a hostile, potentially deadly environment for unprepared humans. In hot deserts, high temperatures cause rapid loss of water due to sweating, and the absence of water sources with which to replenish it can result in dehydration and death within a few days. In addition, unprotected humans are also at risk from heatstroke.

Humans may also have to adapt to sandstorms in some deserts, not just in their adverse effects on respiratory systems and eyes, but also in their potentially harmful effects on equipment such as filters, vehicles and communication equipment. Sandstorms can last for hours,...
