What is the measure of metallic bond strength? The amount of energy as heat required to vaporize the metal is a measure of the strength of the bonds that hold the metal together. The enthalpy of vaporization is defined as the amount of energy absorbed as heat when a specified amount of substance vaporizes at […]
How do ocean surface currents affect climate?
How do ocean surface currents affect climate? Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. How […]
How can I not believe in astrology?
How can I not believe in astrology? Realize that horoscopes are just for fun and do not mean anything. Check your horoscope (hopefully for the last time). Look at what your horoscope says. Then look at a different sign’s horoscope. If you find yourself thinking that you need to change to fit a horoscope, you […]
What can we learn from radial velocity?
What can we learn from radial velocity? The radial velocity technique is able to detect planets around low-mass stars, such as M-type (red dwarf) stars. This is due to the fact that low mass stars are more affected by the gravitational tug of planets and because such stars generally rotate more slowly (leading to more […]
How can joints be classified?
How can joints be classified? A joint is defined as a connection between two bones in the skeletal system. Joints can be classified by the type of the tissue present (fibrous, cartilaginous or synovial), or by the degree of movement permitted (synarthrosis, amphiarthrosis or diarthrosis). What are the different types of joint? What are the […]

Which way is the South American plate moving?
Which way is the South American plate moving? Geological research suggests that the South American Plate is moving westward away from the Mid-Atlantic Ridge: “Parts of the plate boundaries consisting of alternations of relatively short transform fault and spreading ridge segments are represented by a boundary following the general trend.” As a result, the eastward […]
What will happen if tectonic plates continue to move?
What will happen if tectonic plates continue to move? One big problem with plate tectonics stopping is that plate motion is the mechanism by which Earth is cooling down and getting rid of its internal heat. If the plates stopped moving, the planet would have to find a new and efficient means to blow off […]
What is the relationship between frequency and wavelength in sound waves?
What is the relationship between frequency and wavelength in sound waves? Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio. What is the formula to […]
What states have no seat belt laws?
What states have no seat belt laws? New Hampshire is the only state that has no enforceable laws for the wearing of seat belts in a vehicle. What happened to automatic seat belts? Though more awkward for vehicle occupants, most manufacturers opted to use less expensive automatic belts rather than airbags during this time period. […]
