Approximately 20% or of the surface of the Earth falls into
this category. The temperatures are very low in the tundra. In the
winter time they can be as low as -70 degrees. In the summer it is
rarely about 40 degrees. There are lots of rocks too but not very
much vegetation. There are almost no trees at all found in this
particular biome. Tundra Click the arrow to return to the main

The temperature in the coral reef is usually 70 degrees to 85
degrees. Warm water temperatures are required for a coral reef to
exist. That is why they are in the water that is shallow. In the
deeper locations of water, the sun isnt able to shine due to the
depths of it. There are many various small animals that live in all
parts of the coral reef. The largest corral reef in the world is
found in the Northeast of Australia. It is called the Great Barrier
Reef. Coral Reef Click the arrow to return to the main menu

Savannas are found in the lower latitudes. The largest place
where you will find the savanna is in Africa. In fact, 46% of the
land there is a savanna. There is both a dry and a rainy season
that occur in the savannah biome. These each last for extended
periods of time. As a result the supply of food can be very high at
some times of the year. Then they are very low at others. There are
only a few scattered trees found in the savanna. Savanna Click the

Mountains cover about 20% of the Earth's surface and are found
on all continents and in all oceans. The movement of the earth's
crust by folding, breaking into large blocks, lifting upwards to
form a dome, or cracking due to volcanic activity forms mountain
ranges. In certain mountain ranges, the temperature could drop
within about 10 minutes, a thunderstorm may come over a hill
without warning, or a forest might open into a large meadow.

You will find grasslands in the middle latitudes. Those that
have oceans close by get more rain. They also have colder winters.
The temperatures can be from -40 degrees in the winter to about a
comfortable 70 degrees in the summer. There are two seasons here
the growing season and the dormant season. During the dormant
season nothing is able to grow due to the very cold temperatures.

Slide 9
Annual rainfall in the desert is less than 10 inches and, in
some years, may be zero. Because of the extreme dryness of the
desert, its colonization is limited to plants and very few animals.

Slide 10
It is a land dominated by conifers, especially spruces and
firs. It is dotted with lakes, bogs, and marshes. It is populated
by a limited variety of plants and animals. In North America, the
moose is such a typical member that it has led to the name:
"spruce-moose" biome. Before the winter sets in, many of the
mammals hibernate, and many of the birds migrate south. Although
the long days of summer permit plants to grow luxuriantly, net
productivity is low. Taiga Click the arrow to return to the main

Slide 11
The vegetation is so dense that little light reaches the forest
floor. The tropical rain forest exceeds all the other biomes in the
diversity of its animals as well as plants. Most of the animals
mammals and reptiles, as well as birds and insects live in the
trees. Tropical Rainforest Click the arrow to return to the main

rainfall every year? A. Tropical Rainforest B. Desert C. Tundra
Review Question
Slide 13
The Tropical Rainforest actually gets the most precipitation
annually! It receives an average of 50-260 inches of rain yearly.
