Why Mars is Called the Red Planet?

Why Mars is Called the Red Planet?
Mars is fourth in the order of the planets from the sun; it comes after Mercury, Venus and Earth. For years, scientists and experts have been interested about the physical characteristics, structure and composition of its neighboring planet. They have conducted numerous explorations in the past, but there are still many other important questions at the back of their minds. As part of the solar system, it is quite interesting to find out why Mars is called the red planet. The Reason Behind the Red Appearance of Mars Why is Mars called the red planet? Due to its red appearance, many people have referred to Mars as the ‘Red Planet.’ The primary reason behind this is the prevalence of iron oxide, which is commonly referred to as rust. It produces a red-orange appearance right at the planet’s...

Why Does Copper Oxidize?

Why Does Copper Oxidize?
Copper is an industrial metal that has been in use since ancient times. It is a malleable metallic element, which serves various uses. It can be made into thin sheets and can be used to make thin wires since it is quite ductile. It is also a necessary element found in our bodies. And like other elements, it also oxidizes like iron and aluminum. Understanding Oxidation Oxidation is a phenomenon that occurs in everyday life. You would notice that a freshly cut apple would turn brown when it is exposed to the air. When oxidation occurs that element will eventually lose electrons while interacting with another element. Another example of this that we regularly see in daily life is the formation of rust on iron. Effects of Oxidation When exposed to air, iron forms a flaky reddish outer layer, which...

Why Does Copper Turn Green?

Why Does Copper Turn Green?
There are a lot of facts about copper that people may not know about. The following information will show just how prevalent it is. Why it Turns Green The reason it changes color is because of chemical reaction. When exposed to oxygen, it will assume that color. For Electrical Wiring Part of the basis why this element is useful is that it conducts electricity well. It’s this reason that it has come into use in many electrical equipment. Today the industry is one of the biggest consumers of the element. One of its most attractive features is that it becomes easy to use in electrical wiring. Because it makes wiring simple, a lot of appliances and gadgets make use of it. For Decorations Other facts about copper include the ease with which it can be fused with other elements. For...

Why is Zoology Important to Us?

Why is Zoology Important to Us?
Students who spend hours studying it may be asking why zoology is important. It doesn’t concern people, so what practical uses does it have? It’s a legitimate question. For those who are asking why, here are the answers. To Appreciate Nature If you don’t know anything about animals or biology, nature seems to be just about chaos. Everything seems to happen at random. But once you study the life cycles and food chain, you’ll have a better understanding of nature’s handiworks. When you look at the subject, you learn why animals behave this way or that way. It makes one admire nature even more. The reason why zoology is important is that it gives you the opportunity to see nature for what it really is. Not random chaos, but various life forms that interact with one another in amazing...

Why is Pluto Not a Planet?

Why is Pluto Not a Planet?
There are several reasons given by astronomers as to why Pluto is no longer a planet. To better understand it, some background information is essential. Discovery and Classification In 1930 Clyde Tombaugh spotted the object over Arizona. It wasn’t entirely unexpected. The movements of the other planets suggested the existence of another one. Even before its discovery, scientists were confident in its existence, which they called Planet X. The Kuiper Belt Early on, it was assumed the Solar System consisted of the nine planets, their satellites, comets and the asteroid belt. Over the years, several heavenly bodies were discovered. Eventually scientists discovered the existence of the Kuiper Belt. These objects covered the space from Neptune up to 55 AU (astronomical units). This discovery...
