Desert Questions and Answers (Q&A)

Being an explorer is actually a fun activity. Exploring has the tendency to open up the mind to so many possibilities that the person never thought was possible in the past. I have always loved adventures and the fact that I was asked to explore made me giddy with excitement.

I had a lot of fun learning about the way that explorers actually lived. I also have more understanding now of the problems that explorers may face when they are trying their best to learn more about the areas and the people that they were exploring. It did help that I was with other people who love exploring as much as I do. It has made the project more fun.

Tundra and Desert are known to be two different types of biomes that can be found in various parts of the globe. Tundra is known to be a very cold region. It is not uncommon for Tundra to be covered in snow the whole year. The Desert is known to be a biome wherein the temperatures are normally high and hot.

It will not be common for the Desert not to have any water because this can be very hot. Take note that while their temperatures are different, they do have one similarity, and that is a decreased amount in rainfall for both of these regions. Some even say that Tundra is like a desert but with snow instead of sand.

The northern thin fringe of the Sahara desert gets more winter cloudiness along with rainfall. This is because of the arrival of such low pressure systems from over the Mediterranean Sea. The attenuated and the rain shadow effects of the mountains and the subsequent annual average rainfall commonly ranges from 100 millimeters all the way up to 250.

Usually, the definition of a desert is a place that gets less than 10 inches or less than 25 centimeters of precipitation each year. We think of hot areas and we also think of rain, but precipitation can be through rain or through snow. Both hot or cold deserts are places quite lacking in precipitation.

The hottest desert in the world is the Sahara Desert. The highest temperature recorded on the land surface is 136° F in the place called El Aziza, located in Libya. Even though these records are disputed, such a temperature was recorded on September 22, 1922.

This 136° F (58 degrees Celsius) temperature is extremely hot, and it is almost impossible to survive. Vegetation just can't survive and as a result, animal life cannot be sustained without vegetation. The lack of rain and the subsequent lack of water also make these places Which types oftoner. This is the plight of this land where for so long such high temperatures have made it difficult to sustain life.

Temperatures seem to rise in various places as a result of global warming which has become a concern for so many nations. As temperatures rise in Greenland, its ice begins to melt. Certain types of plants and trees are also affected by warmer temperatures, and create a problem for people who live there. About 80 percent of the population is the Inuit people and they are tremendously affected.

About ten percent of the total water reserves of freshwater is there in Greenland in the form of ice. There is an increasing question of the effect of global warming on Greenland and the ice that is there. If that ice begins to melt, it will bring in huge amounts of water into the oceans, and possibly increase the water levels all over the world.

When you hear the term desert, you'll have pictures of scorching heat and temperatures that are so high that it is nearly unbearable. You would also think of camels and cactus as you go through the desert. The most common idea of a desert is a place with very little precipitation. But cold deserts can be shown as deserts whose temperatures range from hot summers to extremely cold winters.

There are some scientists who see Antarctica to be a certain type of a cold desert, simply because of its precipitation. Deserts are split into two sub categories. Cold deserts are not common, but these places are not expected in our way.

The McMurdo Dry Valleys is a small section of Antarctica. This place is commonly referred to as the driest place on the earth. They are referred to as such because of their low humidity and that they lack both snow and ice cover. It would certainly be hard to believe this, but the Sahara Desert could not even be put on the top ten list of the driest places on the earth.

This is a fact that is much beyond common understanding. You see, there is this limited area of the Antarctic that has such features. But their Dry Valleys are really the world's driest place.

The desert called The Atacama Desert is called Desierto de Atacama in the Spanish language. This is a location that is a desert plateau located in South America. This area covers a 1,000 kms (600 miles) locality. This location is west of the Andes mountains. This Atacama desert is surely one of the driest places in the entire world.

Now, the driest is the McMurdo Dry Valleys. Rainfall is quite unusual because of this locality an rarely can be counted as such a place. Only after 400 years did this place receive any rainfall. Thus it is surely one of the driest or the most dirtiest place on the earth.

There are five types of deserts classified in the world today. Some are subtropical, coastal, rain shadow, interior, and polar. These places are so varied as to their location on the various continents that it defies logic. You would normally expect deserts to be nearest to the equator, but that is not the case.

As there are five types of deserts in this world, only about 20% of these deserts are covered in sand. Cold deserts are often covered in ice or snow, and these are surely different from those hot deserts. But according to definition, deserts are places with the lowest precipitation. Now, the largest hot desert on Earth is the Sahara desert.

How come the Atacama is extremely dry when it is so close to the ocean? This is a challenging question to consider, especially considering the proximity to the ocean. The first consideration is that there are two mountain ranges that create a rain shadow that literally keeps rain clouds from entering this area. The second reason is that there are some winds which are called the Pacific Anticyclone that permeate the area. The third thing to keep in mind is that there is another prominent air flow called the Walker circulation which causes air to descend near the Atacama.

Since this air is extremely dry, this keeps the entire area dry. Finally, there is an ocean current, the Humboldt Current, sometimes called the Peru Current, which brings cold water northward along the coast of the continent. This cold air keeps the air dry because cold air doesn't hold much water.
