What time period are we in?
In geochronology, an epoch is a subdivision of the geologic timescale that is longer than an age and shorter than a period. We are currently living in the Holocene Epoch of the Quaternary Period. Rock layers deposited during an epoch are called a series.

Which is the highest mountain peak in the world?
Mount Everest is called the world's highest mountain because it has the highest elevation above sea level. We could also say that it has the "highest altitude". The peak of Mount Everest is 8,850 meters (29,035 feet) above sea level.

What makes something acidic or basic?
When a hydrogen ion is released, the solution becomes acidic. When a hydroxide ion is released, the solution becomes basic. Those two special ions determine whether you are looking at an acid or a base. For example, vinegar is also called acetic acid.

How long does it take for your body to digest a piece of gum?
You might have heard that swallowed gum stays in your stomach for 7 years. That's not true. Though your stomach can't break down a piece of gum the same way it breaks down other food, your digestive system can move it along through normal intestinal activity.

Why does the moon appear to change shape?
The Moon appears to change shape because we see different amounts of the lit part as the Moon orbits Earth. When the Moon is between Earth and the Sun, the lit side is hidden from us. As it moves around Earth, more and more of the lit side comes into view.

Where do the lines of latitude start?
Measure of latitude starts at the equator and is measured as 90 degrees north to the North Pole and 90 degrees south to the South Pole. Each degree represents 60 nautical miles on the earth's surface. The lines of longitude run north and south and are not parallel to each other.

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.

How many pairs of ribs does a horse have?
Normally, there are 18 pairs of ribs in the horse, but a nineteenth rib on one side or both is not considered all that rare. Eight pairs of ribs are known as true ribs. They join the segments of the sternum or breastbone. The other 10 are known as floating ribs--merely overlapping and being attached to each other.

How long does it take to recover from giving blood?
Your body will replace the blood volume (plasma) within 48 hours. It will take four to eight weeks for your body to completely replace the red blood cells you donated. The average adult has eight to 12 pints of blood. You will not notice any physical changes related to the pint you donated.

Do starfish have a brain?
The nervous system of the starfish is very simple...there is no brain and there are not even any ganglia to coordinate movement. The nervous system is characterized by a nerve ring that surrounds the mouth. A radial nerve branches off of the nerve ring and extends to each arm.

What does a lunar eclipse look like from Earth?
Lunar eclipses occur when Earth's shadow blocks the sun's light, which otherwise reflects off the moon. There are three types — total, partial and penumbral — with the most dramatic being a total lunar eclipse, in which Earth's shadow completely covers the moon.

Are dogs and cats related?
Cats, dogs and bears all belong to the Carnivora clade of mammals, but they are not the only ones belonging to this clade. For instance, cats are more closely related to mongoose and hyenas than to dogs or bears, who in turn are more closely related to raccoons, weasels, and walruses.

Do evergreen trees lose their leaves?
Deciduous trees shed their leaves usually as an adaptation to a cold or dry season. Most tropical rainforest plants are evergreens, replacing their leaves gradually throughout the year as the leaves age and fall, whereas species growing in seasonally arid climates may be either evergreen or deciduous.
