Slide3

Forests used to cover the Eastern half of the United States, and most of southern Canada.

Most forests are not too

hot

, or not too

cold

, and have moderate amounts of precipitation. Slide4

ALFISOL

Moderately WeatheredSlide5

SPODOSOL

Sandy, AcidicSlide6

There are two main types of forests.

Pine forests have ashy white layers (

E horizons

) and are called

Spodosols

.

Deciduous forests have soils called

alfisols

, and are not as leached. But clay accumulates in the

SUBSOIL.Slide7

There are a lot of

organisms

in the woods.

Like salamanders, chipmunks, squirrels, and deer.

There are a lot of

TREES

, mosses, fungi and bacteria.Slide8

The

BIGGEST

organism on the Earth is actually a

FUNGUS

in a temperate forest!Slide9

Can you think of a place that relief would be steep?Slide10

Forests are Important to the Carbon Cycle

Temperate forests store carbon in trees and soils, which keeps it from being released into the air.Slide11

CLEAR CUTTING

is removing all trees at once.

Why could this be a problem? Slide12

FORESTS

are FILTERS.

PLANTS

and

SOILS

work together to remove germs, extra nutrients, and other pollutants from the

WATER.Slide13

Vocabulary

Spodosols

– acidic, sandy forest soils under conifers

Alfisols

- moderately leached soils often found in temperate forests

Respiration – animals breathing in and out generate carbon dioxide

Carbon dioxide – a greenhouse gas
