Do ionic bonds share electrons? The two most basic types of bonds are characterized as either ionic or covalent. In ionic bonding, atoms transfer electrons to each other. In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons. Do ionic bonds have low […]
Why is water important in the carbon cycle?
Why is water important in the carbon cycle? Water provides the ingredients needed for plants to do photosynthesis and remove carbon dioxide. The oceans are another important carbon sink. Oceans take in carbon dioxide, which is either dissolved or incorporated into sea plants or animals. Is the carbon cycle a positive feedback loop? Complex systems […]
Why is frog population decreasing?
Why is frog population decreasing? Why Are Amphibian Populations Declining? Clearly, the most important factor leading to amphibian population declines is habitat destruction. The causes for recent amphibian declines are many, but an emerging disease called chytridiomycosis and global climate change are thought the be the biggest threats to amphibians. What would happen if frogs […]

What are the 5 imaginary lines on Earth?
What are the 5 imaginary lines on Earth? International Date Line, Latitude, including the Equator, Longitude, the prime meridian, the Tropic of Capricorn and the Tropic of Cancer. Any axis about which an object spins is an imaginary line. Which is the most important imaginary line on the Earth for time? prime meridian What are […]
Can we prove time dilation?
Can we prove time dilation? There are several direct proofs of time dilation. Extremely accurate clocks have been flown on jet aircraft. (The clock in motion shows a slightly slower passage of time than the one at rest.) In nature, subatomic particles called muons are created by cosmic ray interaction with the upper atmosphere. How […]
Why are there so many concussions in football?
Why are there so many concussions in football? Common Causes of Football Concussions. The most common origins of football concussions that we see in our clinic are from helmet-to-helmet contact in blocking and tackling and from head-to-ground impacts. It’s important to remember, however, that anyone can suffer a concussion from being hit or jostled hard […]
How do atoms combine together?
How do atoms combine together? The atoms of molecules are linked together through a reaction known as chemical bonding. The transfer or sharing of electrons of the atoms in a compound forms a linkage between them which chemists call the chemical bond. There are two types of chemical bonds, (1) ionic bond and (2) covalent […]
Is the sun bigger than the North Star?
Is the sun bigger than the North Star? Scientists using a new telescope found the size of the North Star, also known as Polaris. It turns out that Polaris is 46 times larger than the Sun. It is no surprise to scientists, because Polaris is a cepheid star. Cepheids are special stars that pulsate at […]
Which liquid travels the slowest which liquid travels fastest?
Which liquid travels the slowest which liquid travels fastest? Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound. Why light travels fastest in vacuum? Answer. Yes light travels faster in vacuum than any other medium. […]
