A harsh environment can generally be described as a setting in which survival is difficult or impossible. The extreme cold of the Russian Siberia, -70°C, or the extreme heat of the Sahara Desert, 57°C, may be considered to be harsh environments for humans.

What is an example of an extreme environment?
Examples of extreme environments include the geographical poles, very arid deserts, volcanoes, deep ocean trenches, upper atmosphere, outer space, and the environments of every planet in the Solar System except the Earth.
Where are extreme environments located?
Arid environments are typically found around latitudes of 30° North and South of the Equator. Polar environments and tundra are located in the Arctic circle and the coastline of the Antarctic continent. However, high altitude extreme environments are spread throughout the globe wherever mountain ranges are found.
What are the 5 extreme environments?
Major classes of extreme environments encompass acidic (pH < 5), alkaline (pH > 9), hypersaline (salinity > 35‰), pressurized (> 0.1 MPa), hot (> 40°C), cold (<5°C), dry (aw < 0.80), and high-radiation environments. These environments typically harbor specially adapted organisms, the so-called extremophiles.
How harsh is space?
Space may seem calm, but it is a more hostile environment than that on Earth. ... Beyond the risk of colliding with other objects in space, there are four main dangers for such electronic devices: the empty vacuum, extreme temperature variability, small meteorite impacts and radiation damage.
How do humans survive in extreme environments?
That we can live in cold climates is a result of behavioural adaptations such as wearing appropriate clothing and building shelters. ... Firstly, generating sufficient body heat by burning food and secondly, preventing the loss of that heat by suitable clothing and shelter.
What makes the Arctic an extreme environment?
Due to its high latitude and the tilt of the earth, the arctic experi- ences light and temperature extremes throughout the calendar year. Temperatures range from 60°F (50° C) in the winter to 77° F (25° C) in the summer. ... Hundreds of plant species have adaptations allowing them to thrive in the arctic region.
Why is space considered an extreme environment?
Space is one of the most extreme environments imaginable. Above the insulating atmosphere of the Earth, spacecraft are subjected to extremes of temperature, both hot and cold, and a significantly increased threat of radiation damage.
Why are deserts extreme environments?
They are extremely dry and parts of them are thought not to have received any rainfall, or other precipitation, for at least the last two million years. Deserts result from low rainfall but they are also places of extreme temperatures and of rapid changes in temperature.
Are known as extremophiles?
Extremophiles are organisms that live in "extreme environments," under high pressure and temperature. Bacteria often form on the rocks near the hydrothermal vents. ... The unique enzymes used by these organisms, called "extremozymes," enable these organisms to function in such forbidding environments.
Why can archaebacteria survive in harsh environments?
Presence of peptidoglycan in cell wall help archaebacteria to survive in extreme conditions.
How long would it take to fly to Mars?
The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft's flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
What are some of the harsh conditions of space?
2. Extreme conditions in the ISS space environment include exposure to extreme heat and cold cycling, ultra-vacuum, atomic oxygen, and high energy radiation.
How cold is space?
If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
