Why does the moon control the tides?
The tides are due to the gravitational pull of the Moon and the Sun on the Earth. Because the gravitational force decreases as the distance squared, the part of the Earth that is closer to the Moon or the Sun is pulled a little extra and a bulge is created.

Is a Cashew a nut or seed?
The true fruit of the cashew tree is a kidney or boxing-glove shaped drupe that grows at the end of the cashew apple. The drupe develops first on the tree, and then the pedicel expands to become the cashew apple. Within the true fruit is a single seed, the cashew nut.

Is the blue part of the flame the hottest?
Flame color varies depending on what you're burning and how hot it is. Color variation within in a flame is caused by uneven temperature. Typically, the hottest part of a flame -- the base -- glows blue, and the cooler parts at the top glow orange or yellow.

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.

How does a lunar eclipse occur?
Solar and lunar eclipses are dependent on the alignment of the sun, moon and Earth. When the moon is aligned exactly between the Earth and the sun, the shadow of the moon blocks the sun from view. A lunar eclipse occurs when the moon passes into the shadow of the Earth.

How high is the top of the atmosphere?
Earth's atmosphere is about 300 miles (480 kilometers) thick, but most of it is within 10 miles (16 km) the surface. Air pressure decreases with altitude. At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter).

What causes a double rainbow?
Secondary rainbows are caused by a double reflection of sunlight inside the raindrops, and appear 10° outside of the primary rainbow at an angle of 50–53°. As a result of the second reflection, the colours of a secondary rainbow are inverted compared to the primary bow, with blue on the outside and red on the inside.

What mineral is the hardest?
In Mohs scale, the diamond is always at the most top of the scale, being the hardest mineral. There are ten minerals in Mohs scale, talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and for last and the hardest, diamond.

Why is it called a wisdom tooth?
Wisdom teeth are called wisdom teeth because they erupt (emerge) into the mouth when people are in their late teens or early twenties, affectionately termed the “Age of Wisdom.” Wisdom teeth are technically referred to as third molars, and they're just like all the other teeth in your mouth.

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.
