Why does Death Valley get so hot?
Why so Hot? The depth and shape of Death Valley influence its summer temperatures. The valley is a long narrow basin 282 feet (86 m) below sea level yet is walled by high steep mountain ranges. The clear dry air and sparse plant cover allow sunlight to heat the desert surface. See also who runs the country
Was Australia ever covered in ice?
The last Glacial Maximum (LGM) occurred between 25-16 thousand years BP. There is strong evidence that humans had occupied Australia 45 000 aBP (1).

Can dinosaurs come back?
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
How long did the ice age last?
The Ice Ages began 2.4 million years ago and lasted until 11 500 years ago. During this time the earth’s climate repeatedly changed between very cold periods during which glaciers covered large parts of the world (see map below) and very warm periods during which many of the glaciers melted.
Can a virus survive in space?
As noted by BBC Science Focus viruses can’t survive for long without viable host most can live for hours in the air and days on indoor surfaces at room temperatures. And that’s under ideal conditions. Even the toughest nastiest pathogen would find it problematic to stay alive in the freezing dark of space.
Did the ice age cover the whole earth?
During the last ice age which finished about 12 000 years ago enormous ice masses covered huge swathes of land now inhabited by millions of people. Canada and the northern USA were completely covered in ice as was the whole of northern Europe and northern Asia.

How cold were the oceans during the ice age?
about 46 degrees FahrenheitThe average global temperature during the period known as the Last Glacial Maximum from roughly 23 000 to 19 000 years ago was about 46 degrees Fahrenheit (7.8 degrees Celsius) some 13 degrees Fahrenheit (7 Celsius) colder than 2019 the researchers said on Wednesday.

Did humans live during the last ice age?
The analysis showed there were humans in North America before during and immediately after the peak of the last Ice Age. … This significant expansion of humans during a warmer period seems to have played a role in the dramatic demise of large megafauna including types of camels horses and mammoths.
What does space smell like?
Astronaut Thomas Jones said it “carries a distinct odor of ozone a faint acrid smell…a little like gunpowder sulfurous.” Tony Antonelli another space-walker said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time when I …
How much colder was the last ice age?
The Last Glacial Maximum ended around 19 000 years ago. Scientists have predicted that the global ice age temperature was around 46 degrees Fahrenheit (7.8 degrees Celsius) on average. However the polar regions were far colder around 25 degrees Fahrenheit (14 degree Celsius) colder than the global average.

What is the Earth’s temperature?
NASA has reported that the average temperature of the earth is 15°C. However extreme temperatures are still possible on Earth. The hottest temperature ever recorded on Earth was measured to be 70.7°C in the Lut Desert of Iran in 2005 and the coldest temperature was -89.2°C in Vostok Antarctica.
Would humans be able to live with dinosaurs?
“If we speculate that humans had evolved alongside dinosaurs then they probably would have been able to co-exist ” says Farke. “Humans already evolved in ecosystems that had large land animals and predators. … “But overall humans are pretty good at surviving alongside large dangerous animals.”
How did humans survive the ice age?
Fagan says there’s strong evidence that ice age humans made extensive modifications to weatherproof their rock shelters. They draped large hides from the overhangs to protect themselves from piercing winds and built internal tent-like structures made of wooden poles covered with sewn hides.
The Geography of the Ice Age
When did the first humans appear?
Bones of primitive Homo sapiens first appear 300 000 years ago in Africa with brains as large or larger than ours. They’re followed by anatomically modern Homo sapiens at least 200 000 years ago and brain shape became essentially modern by at least 100 000 years ago.
Did humans and dinosaurs live at the same time?
No! After the dinosaurs died out nearly 65 million years passed before people appeared on Earth. However small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
How cold was the ice age?
Officially referred to as the “Last Glacial Maximum” the Ice Age which happened 23 000 to 19 000 years ago witnessed an average global temperature of 7.8 degree Celsius (46 F) which doesn’t sound like much but is indeed very cold for the average temperature of the planet.
How cold can a human survive?
The record for the lowest body temperature at which an adult has been known to survive is 56.7 F (13.7 C) which occurred after the person was submerged in cold icy water for quite some time according to John Castellani of the USARIEM who also spoke with Live Science in 2010.
What was the hottest period on Earth?
EoceneThe Eocene which occurred between 53 and 49 million years ago was Earth’s warmest temperature period for 100 million years. However the “super-greenhouse” period had eventually become an icehouse period by the late Eocene.
When the next ice age is predicted?
Researchers used data on Earth’s orbit to find the historical warm interglacial period that looks most like the current one and from this have predicted that the next ice age would usually begin within 1 500 years.
Was Africa cold during the ice age?
the climate was dry and cold and forest much reduced and fragmented. The last glacial period as a whole (12 000–70 000 B.P.) was dry in tropical Africa and so too were most of the other 20 major ice ages which have occurred since 2.43 Myr B.P. in comparison with intervening interglacials.
What did humans eat during the ice age?
It is likely however that wild greens roots tubers seeds nuts and fruits were eaten. The specific plants would have varied from season to season and from region to region. And so people of this period had to travel widely not only in pursuit of game but also to collect their fruits and vegetables.
