All the communities that live in an area together with the abiotic factors.

Front 5

Rainwater moving through the soil carrying minerals down deeper into the ground.

Front 9

Pavement

Back 9

Wet land region between 23 degrees N and 23 degrees S latitude.

Front 12

Rainshadow Effect

Back 12

When warm, moist air cools and loses most of its moisture as precipitation over the western side of mountainous regions and on the eastern side of the mountains the cool dry air picks up moisture from the soil causing it to dry out and form a desert.

Front 13

Migration

Back 13

Long distance seasonal travel by animal populations.

Front 14

Succulents

Back 14

A plant such as a cactus that has thick water filled tissues.

Front 15
