These are the only two planets in our solar system without moons... A: Mercury & Venus, B: Venus & Mars, C: Uranus & Neptune, D: Neptune & Pluto

What is A: Mercury & Venus. As far as we know, Saturn has the most moons. Saturn has at least 25 satellites that measure at least 6 miles (10 kilometers) in diameter, and several smaller satellites. The largest of Saturn's satellites, Titan, has a diameter of about 3,200 miles (5,150 kilometers) -- larger than the planets Mercury and Pluto.

This type of matter has a definite volume but no definite shape... A: Solids, B: Liquids, C: Gases, D: Plasma
What is B: Liquids. Liquids have a definite volume but no definite shape. Because the intermolecular forces are weak in a liquid, it is able to change its shape to conform to its container.

This geologic formation may be found overhead if you are in a cave... A: stalactites B: stalagmites C: mightymites D: termites
What is A: stalactites. The ones growing downward are stalactites, the ones growing upward are stalagmites. Stalactites are formed by the deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions.

This metal has a melting point so low that it can melt from the heat of your hand. A. Iron  B. Vanadium  C. Lithium  D. Gallium

What is D - Gallium: It melts just above normal room temperature, meaning a solid piece will liquefy right in the palm of your hand.

This type of water weighs the most... A: seawater B: distilled water C: tap water D: none - They all have the same weight.
What is A: sea water. It is loaded with mineral salts and weighs about a pound and a half more per cubic foot than fresh water at the same temperature.

Of the following, it has the longest recorded life span. A: Termite, B: Chimpanzee, C: Indian Elephant, D: Freshwater Oyster
What is the Freshwater Oyster (80 years.) The longest recorded life span for a termite is 50 years; for a chimapanzee, 50 years; and for an Indian elephant, 70 years.

What is the name of the comet that travels through our solar system that is visible from earth every 75-76 years?  A. Halley's Comet   B. Hale-Bopp Comet C. Borrelly Comet  D. Persied Comets

What is A. Halley's Comet

Matter that does not enter chemical reactions is described as this... A: Inhibited, B: Inert, C: Grounded, D: Radioactive
What is B: Inert. Inert matter does not enter chemical reactions.
300
This is the hardest naturally occurring substance... A: emerald B: tourmaline C: diamond D: corrundum
What is C: Diamond. Diamond is also one of the most valuable natural substances. Diamonds are crystals formed almost entirely of carbon. Because of its hardness, the diamond is the most enduring of all gemstones. They are among the most costly jewels in the world, partly because they are rare, Only four important diamond fields have been found - in Africa, South America, India, and the Soviet Union.

This is the term for an object in space is caught inside a black hole.  A: Occultation, B: Parallax, C: Thinning, D: Spaghettification

What is D: Spaghettification. It is caused by extreme tidal forces. In the most extreme cases, near a black hole, the stretching and compression are so powerful that no object can resist it.

These substances control the rates of chemical reactions... A: Reactants, B: Catalysts, C: Isotopes, D: Cathodes
What is B: Catalysts. Catalysts are substances that control the rates of chemical reactions.

The largest hailstone recorded was closest to this object in diameter... A: basketball B: softball C: tennis ball D: golf ball
What is A: basketball. The largest hailstone ever recorded was 17.5 inches in diameter - bigger than a basketball.

This animal has the highest blood pressure... A: Giraffe, B: Blue Whale, C: Elephant, D: Flea
What is A: Giraffe. Because of its extremely long neck, the giraffe must rely on its oversized heart (two feet long and twenty-five pounds!) to pump blood all the way to its head. As a result, the giraffe has the highest blood pressure of any animal: 280/180 mmHg (millimeters of mercury) at heart level when prone -- more than twice the blood pressure of an average human. Not surprisingly, because of their high blood pressure, giraffes are prone to heart attacks.

B) Similar chemical and physical properties   

C) Same exact density at room temperature    

D) Same phase of matter (all solid, liquid, or gas)

What is B - Similar chemical and physical properties
