What country has the largest recorded earthquake?

Though this earthquake was originally reported as having a magnitude of 8.6, scientists have since learned that the model used for calculating earthquake magnitude greatly underestimates the size of large events. After updating the model and recalculating the data from previous earthquakes, the magnitude of this earthquake was adjusted upwards.

Why is coal considered a non-renewable resource?

Coal is used in some areas to create electricity. It is mined and cleaned at the coal mine and then transported via train or barges to the electric plant. When it reaches its destination, the coal is burned in boilers to produce electricity.\nAs of 2014, the estimated amount of coal reserves in the United States is 268 billion tons. Many states have coal mines, but Kentucky, West Virginia, and Wyoming are the three highest producers of coal energy.

What is a comparison microscope?

Comparison microscopes are essentially two separate microscopes connected by a bridge that includes a single viewing lens. Two similar objects can be placed on the opposing stages and be viewed simultaneously in the same viewing field. This greatly assists examiners in comparing two like materials without the need for moving between two separate microscopes.

Does the color of light used on plants affect how well they grow?

Red and blue light promote photosynthesis more than green and yellow light, but light intensity and duration also impact plant growth. Typical indoor conditions provide far less light than outdoor conditions. Indoor lighting is best suited to houseplants with low light requirements. The light requirements and tolerances of outdoor plants range from full sun to closed shade.

In which organelle does photosynthesis occur?

Chloroplasts are made up of small sacs called thylakoid membranes. Each of these flat pancake-like membranes has photosystems set in a ray-like pattern to better capture and hold the light energy for use. Chloroplasts are a type of plastid that circulate and move around inside the plant cells. These organelles reproduce by pinching themselves in two. This process occurs when a plastid dividing ring forms around the center of the chloroplast, then slowly begins to add pressure to the organelle until it splits under the ring leaving two chloroplast where there had been only one. Chloroplasts can..

What are some Genographic Project results?

Participants' results are stored on the Genographic Project website where they can log on and get information on which deep ancestral branch (haplogroup) they most likely belong to.\nA small sample of 326 Puerto Rican subjects supports, but does not prove, theories that Taino men were wiped out by Spaniards in the 15th century, while Taino women survived and procreated with the Spanish invaders. Sixty percent of mitochondrial DNA samples from women showed Taino ancestry, while zero percent of Y chromosome DNA samples showed Taino ancestry. Since mitochondrial DNA is only passed through ma..

What is dinitrogen trioxide used for?

The chemical compound dinitrogen trioxide is commercially used for special purpose fuels due to its highly combustible nature; the chemical doesn't actually burn but only supports combustion. It is more often used in combination with other chemical compounds as it is an oxidizing agent. It creates heat and gas when combined with reducing agents; in a closed container, it causes a pressure build-up and a make-shift rocket is created. As entertaining as this can be, it is also very dangerous.\nDinitogen trioxide is dangerous because of its corrosive nature to the skin, which causes burns. I..

Where can you get potassium nitrate?

Garden supply stores used to sell potassium nitrate under the name saltpeter, but it is harder to find under that name now, according to About.com. Commonly used to make homemade smoke bombs and fireworks, this compound is offered for sale by many online garden and home supply retailers and can also be made using ingredients found in common household items. About.com offers links that give steps to making potassium nitrate at home.

What is Ganoderma lucidum?

Ganoderma lucidum is a member of the group of fungi known as polypores, which have many small holes on their lower surfaces, rather than the more common gills, for releasing spores. Mature fruiting bodies have glossy, deep red surfaces, while younger fungi have more yellow in their coloration. A variation restricted to the southeastern United States has a more yellow coloration even in maturity. Some scientists believe that the latter variety is actually a separate species. Both varieties tend to grow more readily in warm climates.\nGanoderma lucidum is now commonly cultivated for sale in the ..

What is a dendritic pattern?

Dendritic patterns are formed from a kind of growth called diffusion-limited aggregation. Diffusion-limited aggregation occurs when resources travel about randomly until they hit each other and join a static structure. This sort of diffusion-based growth occurs in the flow of water and the formation of lightning strikes. Dendritic drainage systems are not the only pattern in which water may form rivers, they are the most common. Dendritic pattern drainage occurs on flat land with steady water flow and soft, non-porous rock that is free of geological fault lines.
