What percentage of the earth's water is frozen?
Of the three percent of the water that is not in the ocean, about 69 percent is locked up in glaciers and icecaps. Ninety percent of that frozen water is in Antarctica and about nine percent covers Greenland. Of the remaining freshwater, 30 percent of it is groundwater, captured below our feet.

How much of the earth's atmosphere is made up of nitrogen and oxygen?
It is primarily composed of nitrogen (78%) and oxygen (21%) with only small concentrations of other trace gases. Nearly all atmospheric water vapor or moisture is found in the troposphere, so it is the layer where most of Earth's weather takes place.

Why is the ring of fire called the ring of fire?
The area encircling the Pacific Ocean is called the "Ring of Fire," because its edges mark a circle of high volcanic and seismic activity (earthquakes). Most of the active volcanoes on Earth are located on this circumference.

When did Greenwich mean time start?
Greenwich Mean Time (GMT) was adopted as the world's time standard at the Washington Meridian Conference in 1884. This conference also established Universal Time, from which the international 24-hour time-zone system grew. This is why all time zones refer back to GMT on the prime meridian.

Can tonsils grow back after being removed?
During a tonsillectomy, most of the tonsils are removed. However, some tissue often remains, so tonsils can occasionally regenerate — although they probably won't grow back completely or to their original size.

How long do taste buds last for?
Taste buds go through a life cycle where they grow from basal cells into taste cells and then die and are sloughed away. Their normal life cycle is anywhere from 10 days to two weeks. However, burning your tongue on hot foods can also kill taste buds.

How fast does the earth spin?
The circumference of the Earth at the equator is 25,000 miles. The Earth rotates in about 24 hours. Therefore, if you were to hang above the surface of the Earth at the equator without moving, you would see 25,000 miles pass by in 24 hours, at a speed of 25000/24 or just over 1000 miles per hour.

How many languages are there in the world?
There are approximately 6,900 distinct languages in existence today, though there may be languages spoken in remote areas that we have yet to discover. No matter how many new languages we find, though, this number will be much lower in 100 years.

Can female fireflies fly?
Male fireflies can fly, but female fireflies often can't because their wings are too short. The female firefly perches itself on a bush or a rock and waits. When a male passes by with a signal the female recognizes, the female flashes back the same signal.

How does a plant loses water?
Plants lose gallons of water every day through the process of transpiration, the evaporation of water from plants primarily through pores in their leaves. Up to 99% of the water absorbed by roots is lost via transpiration through plant leaves.

What animal sleeps with one eye open?
For dolphins, this is an easy task. They can turn off half their brain and close one eye, allowing them to be partly asleep and awake at the same time. According to an article in the Scientific American , dolphins sleep this way so they can be ready to protect themselves from predators and swim to the surface for air.

What was the first metal used by man?
Over 4,000 years ago, when it was discovered that minerals could be melted, curiosity led man to combine melted metals (alloys). By accident they made bronze by adding tin to copper (the Bronze Age). Another combination of zinc and copper made brass.

What does CT stand for in medical terms?
CT, or CAT as they're pronounced, stands for "computerized axial tomography." In a CT scan, the patient lies on a table that slides into a scanning machine. Inside, an x-ray beam rotates around the body while detectors measure how much of the x-rays pass through the tissues and organs, indicating density.

What animal has four stomachs?
Ruminating mammals include cattle, goats, sheep, giraffes, bison, moose, elk, yaks, water buffalo, deer, camels, alpacas, llamas, and antelope. Ruminants differ from non-ruminants (called monogastrics) because they have a four-chambered stomach.

Which planet has the fastest rotation?
Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.

How long is a kangaroo baby when it is born?
The young kangaroo, or joey, is born alive at a very immature stage(around 36 days of pregnancy) when it is only about 2 cm long and weighs less than a gram. Immediately after birth it crawls up the mother's body and enters the pouch. The baby attaches its mouth to one of four teats, which then enlarges to hold the young animal in place.

Are birds warm blooded or cold blooded?
Mammals and birds are warm-blooded, which means that they can make their own body heat even when it is cold outside. Whether it is sunny and hot outside or there is a snowstorm and it is very cold, warm-blooded animals have body temperatures that usually stay the same.
