We got two biomes……

One is frozen cold in winter and cool in summer

The other is warm in winter and hot in summer

Tundra Tundra usually discovered in high latitude or high altitude, there is small groups of animals can live on it, not only because of the climate, but the soil

Temperate

Grassland

Temperate grassland may seem more comfortable, nice climate, nutrition rich soil. So, many types of animals can be discovered.

Michael’s Time…..

The word comes from Russian, which means treeless mountain

tract.

location

Tundra is identified by permafrost, mostly in 66.5°N, or 66.5°S in far

north side of North American , Russia, The north pole and Europe.

And island near the south pole.

temperature

The temperature during winter can always be -40~-45 or even colder than ℃

that. the highest temperature can reach 18 ℃

during summer time

Water is short in Tundra, and usually are snow

and ice. They would melt when it's getting warmer, and provide water supply

Living Things

In physical geography, tundra is a biome where the tree and animals growth is hindered

by low temperatures and short growing seasons.

The breed of animals isn't that much, but the number can be very large. Some of them will migrate during

different seasons

The living things there usually grows slow

because of the weather and nutrition

what is permafrost

permafrost is soil at or below the freezing point of water 0

°C (32 °F) for two or more years and can reach

hundreds meter below the ground . It's a mixture of soil

and ice (or snow), and ice will melt when the

temperature goes high, in order to provide the soil with

enough water resource.

Abiotic Factors

Animal Life

Plant Life

Strong winds

Long cold dark winters

Short and soggy summers

Low precipitation

permafrost

The types of plants are poor

The community structure is easy.

The plants are usually perennial

Most of the plants are evergreen

Most of the plants are short

The plants are low-growing

NO! Too much to

remember!!!

Don’t cry! There are three

pictures for you as a present!

Animals often migrate

Animals often have adaptation

Animalia is single

The variety is poor

Easy, right? It’s the same thing as the plants! No picture this

time!

BEAUTIFUL!

I think so!

Are you kidding?

Ok, time to go!

•Two huge temperate grassland. -Eurasian steppe. -North American grasslands.

•Temperate grassland is a communities that plants are mostly grass. In this kind of area, soils are always fertile and ideal.

NOT BEDNOT BED

Frank’sTime…..

Its rainfall is not so much, it is only about 200-500mm and has a large variability.It always concentrated in the summer.

Average annual temperature is -3 ～ 9 , ℃

accumulated temperature is 1600 ～ 3200 .The lowest ℃average temperature of a

month is -7 ～ 29 .℃

Understand? If you do not, I’ll scare you at

midnight!

The type of soil is chernozem. This rich soil makes it ideally suited to agriculture and tall grassland

ecoregions.

This part is easy!

I think so!

Temperate Grasslands is a suitable for animals to live, like Mongolia rabbit, fox, wolf, antelope, rat,

dog, etc.

I want pictures!

Don’t cry! Here it is!

You guys must remember what this group has told you, or I and my wife will

go to meet you, tonight…….
