Why red is more energetic than yellow? Since, red light has lower frequency than yellow, yellow has higher momentum than red, not mass. In a way, it’s the momentum of photons which cause the radiation pressure. If the hotter an object, the brighter it glows (more energy), then why is a blue flame less visible […]
What would happen if temperature and precipitation changed in a climate zone?
What would happen if temperature and precipitation changed in a climate zone? Changes in temperature and precipitation can disrupt a wide range of natural processes, particularly if these changes occur more quickly than plant and animal species can adapt. In response, average temperatures at the Earth’s surface are rising and are expected to continue rising. […]
What is the difference between loudness and frequency?
What is the difference between loudness and frequency? Frequency (the number of vibrations or sound waves per second) is measured in Hertz (Hz). A sound that is 4,000 Hz (like the sound the letter “F” makes) has 4,000 waves per second. Intensity (loudness) is the amount of energy of a vibration, and is measured in […]

Had chlamydia for 2 years can I still get pregnant? Most women who have had chlamydia won’t have any difficulties conceiving that are related to the infection. There may be a greater chance of chlamydia affecting fertility if you have repeated infections or if it goes untreated and causes a condition called Pelvic Inflammatory Disease […]
What are the advantages and disadvantages of coal power?
What are the advantages and disadvantages of coal power? Coal energy is an affordable energy source because of the coal’s stable price compared to other fuel sources. Coal is easy to burn. Coal produces high energy upon combustion. Coal energy is inexpensive. Why should we not use coal? In 2012, coal accounted for 37.4% of […]
What causes static electricity in a person?
What causes static electricity in a person? Static electricity is created when positive and negative charges aren’t balanced. Protons and neutrons don’t move around much, but electrons love to jump all over the place! When an object (or person) has extra electrons, it has a negative charge. Why is my laundry so static? What causes […]
Can fossils be found anywhere?
Can fossils be found anywhere? For example, many fossils form when plant and animal remains are buried by mud, sand, or soil. This helps to preserve the remains long enough for them to form fossils. Still, fossils can be found just about anywhere. From the tops of mountains to the depths of the seas, fossils […]

What is the highest sea level in history?
What is the highest sea level in history? The current sea level is about 130 metres higher than the historical minimum. Historically low levels were reached during the Last Glacial Maximum (LGM), about 20,000 years ago. The last time the sea level was higher than today was during the Eemian, about 130,000 years ago.
