Study Notes
Types of Deserts
- Four types of deserts: Hot and Dry, Semiarid, Coastal, Cold.
Abiotic Factors
- Key abiotic factors influencing desert environments include:
- Precipitation
- Water availability
- Sunlight
- Temperature
Biotic Factors
- Notable biotic factors in deserts consist of:
- Drought-resistant grasses
- Cacti
- Aloe plants
- Other succulents
Largest Desert
- Antarctica holds the title as the world's largest desert.
Hottest Desert
- The Sahara Desert in Africa is recognized as the hottest desert globally.
Desert Biome Distribution
- Deserts exist on every continent with the exception of Europe.
Desert Definition
- A desert is defined as a biome characterized by an extremely dry climate, supporting a distinct ecosystem with various adapted animals:
- Examples include: Armadillos, African Wild Dogs, Badgers, Coyotes, Cheetahs, Otters, Rattlesnakes, Pythons, Jaguars, Iguanas, and Cougars.
Rainfall Characteristic
- Deserts are primarily identified by their low levels of rainfall.
Sunlight Exposure
- Due to low humidity and the absence of tall vegetation, deserts receive significant amounts of sunlight.
Coverage of Earth
- Deserts make up approximately 20% of the Earth's surface.
Driest Desert Rainfall
- The driest desert on Earth averages just 1 centimeter of rainfall every 5 to 20 years.
Population in Desert Regions
- Over one-sixth of the global population resides in desert areas.
Nocturnal Activity
- Many desert animals are nocturnal or live underground to adapt to the harsh conditions.
Temperature of the Sahara
- The Sahara Desert can reach extreme temperatures up to 122 degrees Fahrenheit.
Plant Adaptations
- Desert plants have adapted to limited water availability by developing long roots that can access deep groundwater.
Sunlight Intensity
- Deserts experience high levels of sunlight due to minimal humidity and a lack of tall plant life.
