What is the difference between speed and velocity?
-
Speed is faster.
No. An object's speed is part of its velocity. -

They mean the same thing.
No. The two terms have different meanings. -
Speed is a general term and velocity is a scientific term.
No. Both terms are used in science, and they mean different things.

Yes! The liver produces bile, which digests fats. -
Gall Bladder
No. The gall bladder stores the bile, but does not produce it. -
Pancreas
No. The pancreas produces insulin to digest sugar. -
Thyroid
No. The thyroid produces several hormones which control growth and metabolism, but it does not produce bile.

This is the mineral galena. What type of luster does it have?
-
Vitreous
No. A vitreous luster means that the mineral looks glassy. Galena does not look like it is made of glass. -
Shiny
No. Shiny is not a type of luster. -
Metallic
Yes! A metallic luster means that the mineral looks like it is made of metal. Galena reflects light in the same way that a piece of metal does. If a mineral looks like it is made of metal, it has a metallic luster. -
Silver
No. Silver is a color, not a type of luster. Luster is the way that a mineral reflects light, not is color.

How can there be rain if this area is a desert?
Answer:
It is important to understand the difference between climate and weather. Weather is what is happening now. Climate is determined by looking at the weather data over a long period of time, often several decades. To be classified as a desert climate, the area has an average annual rainfall of 7.87 inches of rain or less. That tells us that it does sometimes have rain, just not very often.
