description

The tundra is a very unique biome because it circumnavigates the pole. It is very cold in the tundra. In its summer season it doesn't even get above 40 degrees F. It has very high winds up to 100 mph that makes cold even colder. It is an inhabited place. although there isn't much biodiversity there are animals. Very dry place. almost as dry as some of the dryest deserts on earth.

Tundra Location and Climate

The tundra is located in the upper most part of the earth. Its latitude is from 60 degrees north to 70 degrees north. It doesn't have a longitude because it circles the globe. It is in many countries. Countries included are Russia, U.S.A., Canada, Greenland, Finland, and Sweden.

It is also very cold the whole year round. It has a short summer (about 6 to 8 weeks) where the temperatures are mild, but still not enough to thaw the ground. It is very cold in the winter. Temperatures don't reach above 20 degrees F. The average is -20 to -30 degrees F. The high winds that is in the tundra makes freezing turn into even more freezing.

The tundra is also very dry. it has about 6-10 inches of snow each year inducing melted snow. This is almost as little as the earths driest deserts.

animals

The snowy owl is one of the largest and most attractive owls on earth. It gets its name from its white feathers. The males have more white on them, the females have streaks of black and dark circles around their eyes. The females feathers have adapted to camouflage her as she sits on her eggs. They have very sensitive eyes so they can spot prey under snow.

The arctic fox is a small animal that burrows the ground to live in. has thick fur for the harsh cold. It has a stealthy walk to it. It is a scavenger so will follow other predators to eat their remains. Fur changes color with the seasons for camouflage.

plants

The arctic moss is a moss that lives in the freshwater lakes as well as on the ground. To reproduce it needs to have water. The arctic moss will grow about anywhere and it helps warm the ground to let other plants grow. It grows very slowly. It has adapted to its climate because it will store new leaves in the winter so when its spring it can grow quicker when the sun is out.

The bearberry is a short evergreen that has silky furs on its thick bark. The silky furs helps keep it warm. since it is so short it stays out of the harsh winds. This is one way that it has adapted to its climate. The bearberry produces a small red berry that bears love to eat. This is how it got its name.

2 reasons

The arctic tundra has just always interested me. I love the cold and would love the excitement of the hard life. The main reason i love it though is because it is a perfect picture of how God can take something dry and make it something so beautiful with so many things.
