Sahara desert is the biggest hot desert in the world covering 8% of the whole land. When we think of Sahara desert we probably have that picture of the sand dunes in our heads, but the fact is that most of the Sahara is formed of gravel, not sand. The temperatures in the desert can get really high, unbearably hot, and there is rarely any rain falls in the Sahara, but there are places in the desert where you can find water. Oasis are formed around water, which comes from the underwater rivers that pop up on the surface. In these oases, hundreds of variety of plants can grow. People that actually live in Sahara work on the land in the oasis or have goats and camels. The truth about Sahara is that it’s not the biggest desert in the world, but the biggest HOT desert. The biggest one on the Earth is actually a cold one.
Yes, Antarctica is the biggest desert on the planet. Most of Antarctica is covered in ice, almost 98%. Despite the fact that 70% of the fresh water in the world comes from Antarctica, it is the driest continent and some parts haven’t had any rain or snow for more than a million years. It’s the coldest place on Earth where the lowest temperature ever measured was -90 C with average summer temperatures of -25 C. The average thickness of the ice blocks in Antarctica is about 2 km. If all of the ice melts, it will dramatically increase the sea level which will result in a huge damage to the coastline. You can set your watch as you like in Antarctica. It’s the only continent without a time zone. There are no permanent residents in Antarctica and the visitors are tourists or scientists.

Located in South America, the Amazon Rainforest is the largest tropical rainforest in the world covering 5.5 million km². Tropical rainforests are ecosystems characterized by being warm and wet. Rainforests are the lung of the planet because of their ability to absorb the carbon dioxide and transformed it into oxygen. By providing rainfalls all over the world help in maintaining the water cycle on the earth. The Amazon River in South America is the largest river by discharge volume of water in the world. There are tribes living in the Amazon Rainforest that don’t have any contact with the outside world. Truly it is an enormous space of vegetation and natural resources for which we know about 20 %. So, the Amazon Rainforest stays a mystery to us not yet revealed. We still don’t know what’s actually hiding there.
The Serengeti is an ecosystem located in Africa that is a home to the largest mass movement of land mammals in the world, more than a million and a half. From Serengeti in Tanzania to Maasai in Kenya, and back, these animals migrate in search for food and greener land. The best spots for sighting the animals would be in dry seasons, around the water. One of the most dangerous parts of their movement is while crossing rivers when they become an easy prey for the hippos and crocodiles hiding in the water. The dry season, June to October offers the best wildlife sighting with the Great Migration of the wildebeest as its absolute highlight. The timing of the migration varies every year and the best chance of seeing would be during June and July.
