5. Environmental Factors
Biotic Factors – living or once-living environmental features.

6. Environmental Factors
Abiotic Factors – nonliving physical features.
The abiotic factors in an environment often determine which kinds of organisms can live there.

7. Air and Water
Air - The air that surrounds the Earth is called the Atmosphere.
Consists of mostly nitrogen (78%) and oxygen (21%).

8. Air and Water
Water - The major ingredient of the fluid inside the cells of all organisms.
Respiration, digestion, photosynthesis, and many other important life processes can take place only in the presence of water.

9. Soil and Sunlight
Soil is a mixture of mineral and rock particles, the remains of dead organisms, water, and air.

10. Soil and Sunlight
Sunlight – The source of energy for most life on Earth.
Photosynthesis cannot take place without light.

11. Temperature
The temperature of a region depends in part on the amount of sunlight it receives. The amount of sunlight depends on the land’s latitude and elevation.

12. Temperature
Latitude – areas closer to the equator are warmer than areas farther from the equator.

13. Temperature
Elevation – distance above sea level affects temperature, wind, and soil.

14. Elevation - Rain Shadow
More rain on the windward side of mountains. This often means that the land on the other side of the mountain (the leeward side) gets far less rain—an effect called a "rain shadow"—which often produces a desert.
The higher the mountain, the more pronounced the rain shadow.
The Windward is the side of a mountain that is facing into the direction that the wind is coming from.
The Leeward side is the wind protected side of a mountain.

16. What is Florida’s Climate?
Climate refers to an area’s average weather conditions over time, including temperature, rainfall, or other precipitation, and wind.
For most living things, temperature and precipitation are the two most important components of climate.

17. Climate
Heat energy from the Sun creates air currents called wind.
