Are we on the Earth??

We probably have seen many science fictions or alience movies? but we may not see this on the earth.  Here are some places that you could find in our world and make u wonder "  ARE WE STILL ON THE EARTH?"

1. Dry valley

The Dry Valleys of Antarctica get virtually no snowfall or moisture of any kind. The major Dry Valleys have certain characteristics in common, and some have unique features. They are generally 5-10 kilometers wide (between ridge crests) and 15-50 kilometers long. Only the Taylor and upper Wright Valleys have glaciers at their heads, which connect with the ice of the polar plateau; the other valleys have either barren upper reaches or small alpine glaciers. Only Taylor Valley exits directly to the sea ice of McMurdo Sound, whereas the others are blocked by the Wilson Glacier.Several lakes occupy parts of some valley floors, their surfaces frozen most of the year. Some lakes are over 30 meters deep and have perennial ice covers several meters thick. 

2. Socotra

Socotra, one of the last so-called "lost worlds," an island 250 miles off the coast of Yemen.It is the home of yellow-faced vultures and the tadpole shrimp, thought to be the oldest creatures in the world. It's smothered by beautiful, desolate beaches where the people speak their own language, rubbing their noses and foreheads together as a way of saying, "Hello." Did I mention they have 24 months in a year, one for each season?

3.Spotted Lake 

For a bird's-eye view of the lake and the Similkameen and Okanagan Valleys, follow the gravel road from Osoyoos to the summit of Mt. Kobau, one of the tallest peaks around. A great spot for stargazing and hiking, and the views are nothing short of spectacular. 

Nine kilometres west of Osoyoos on Highway 3 is Klikuk, the Spotted Lake, containing one of the world's highest concentrations of minerals, including epsom salts, calcium, magnesium and many other trace minerals. The healing mud and waters were used to alleviate aches and pains. In the summer the water evaporates and crystallizes, making the white-ringed spots visible.The most amazing part is the water display different colours in four seasons.

 

4.Salar de Uyuni

Salar de Uyuni is part of the Altiplano of Bolivia in South America. The Altiplano is a high plateau, which was formed during uplift of the Andes mountains. The plateau includes fresh and saltwater lakes as well as salt flats and is surrounded by mountains with no drainage outlets.

The geological history of the Salar is associated with a sequential transformation between several vast lakes. Some 30,000–42,000 years ago, the area was part of a giant prehistoric lake, Lake Minchi Its age was estimated from radiocarbon dating of shells from outcropping sediments and carbonate reefs and varies between reported studies. Lake Minchin (named after the Juan B. Minchin of Oruro) later transformed into paleolake Tauca having a maximal depth of 140 meters (460 ft), and an estimated age of 13,000–18,000 or 14,900–26,100 years depending on the source.
