What is it called when two plates meet?

When two plates collide, the front edges of the plates fold and bend. The folding and bending causes rocks to break and slip, which causes earthquakes.\nOther types of boundaries that occur with tectonic plates are divergent boundaries and transform plate boundaries. A divergent boundary takes place when two plates move away from one another; a rift forms, and lava leaks out. A transform plate boundary is defined as two plates moving past each other with no contact.

How does the atmosphere support life on Earth?

The ozone layer, which lies in the upper stratosphere, is the planet's primary protector from electromagnetic radiation in the ultraviolet band of the spectrum. UV rays are invisible to the human eye and are harmful to life. By absorbing the UV radiation, the ozone layer keeps the bulk of rays from reaching Earth's surface. The ionosphere also helps to support life by absorbing energetic protons from the sun.\nWeather and climate take place in the troposphere. The troposphere is also where the water cycle takes place. Water evaporates from the oceans and forms clouds. The clouds the..

How are the genes lined up in a pair of chromosomes?

A chromosome is technically a linear strand of DNA. However, this DNA is tightly coiled into structures called nucleosomes by special protein complexes called histones and further condensed during cell division. As a result, the DNA is coiled and bent over many times, and a gene's location along the condensed chromosome may not reflect its exact location along the chromosome when unspooled. The scaffolding that forms the chromosome's backbone and histones that the DNA wraps around are consistent between chromosomes, so homologous genes line up exactly in paired chromosomes.

What is the chemical name for HCO3?

HCO3 is an anion that carries a total net charge of minus 1. It is used in the formation of many ionic compounds, such as ammonium bicarbonate. Bicarbonate has a molar mass of 61.01 grams per mole and an acidity of 10.3. It is a product of the photosynthesis of freshwater plants, and is commonly found in the compound sodium bicarbonate, also known as baking soda.

What causes neap tides?

Twice a month, during the full and new moons, the sun, moon, and Earth are in alignment with one another and the solar tide works together with the lunar tide, creating very pronounced high and low tides. This type of tidal pattern is called spring tide.During the alternating weeks, the sun and moon are at right angles to one another so the solar tide partially cancels the lunar tide, resulting in a very moderate high/low tide cycle. This pattern is called neap tide and occurs twice monthly.

How is visible light produced?

Light is a wave that also behaves as a particle, which is known as a photon. It comprises several wavelengths, and each has a particular color. The color viewed by the eye is a reflection of specific wavelengths.\nVisible light is only a small portion within the electromagnetic spectrum to which the human eye is sensitive.\nWhite light comprises all colors of in the light spectrum. For instance, light from the sun is an example of white light.\nOn the other hand, monochromatic light produces comprises only one color. Examples include light from a laser.\nThe color of objects that the human eye..

How big is a red giant star?

A red giant star is in the last phase of its life. It forms when nuclear fusion stops and gravity forces the star to contract. Temperatures increase, and helium fuses into carbon. The resulting explosive energy makes the star expand in size and turns it into a red giant. A red giant is so named because its temperature, which reaches 4,000 to 5,800 F, makes the star shine in the red part of the light spectrum.

Which solids and liquids conduct electricity?

Materials can be defined by their electrical conductivity. Materials which do not conduct any electrical current at all are called insulators. There is no such thing as a perfect insulator, but materials which resist current the most strongly include glass, paper, ceramics, most plastics and generally most non-metals. Materials which can conduct some current, but don’t do it very well, are called semiconductors. These include silicon and germanium, and are used frequently in electronics.\nMaterials which conduct current well are called conductors. Solid conductors include most metals, such a..

What color do green and purple make?

There are two different types of color mixing: subtractive and additive. Each of these methods has a different set of primary colors.\nThe three subtractive primary colors, for mixing colorants such as paint, dye and ink, are yellow, magenta and cyan. The combination of these three colors results in black.\nThe three additive primary colors, for mixing light or illumination, are red, green and blue. Combining these colors produces the color white. Mixing red and blue creates magenta, red and green produce yellow, and blue and green combine to make cyan.

Do salt marshes differ from swamps?

Wetlands are areas of land that are almost always covered in water. A marsh is a type of wetland that comes in a range of different types, including salt marshes. There are also freshwater marshes. Salt marshes, though, get their water from the tides. The soil is comprised of deep mud and peat, and it contains a lot of decomposing plant material. Salt marshes are important because they slow flood waters and they protect the rest of the land from the erosion caused by waves.The soil in a swamp is also frequently or continuously covered by water. The difference is that water-tolerant trees grow ..
