How do beaches disappear? When seas rise, it’s inevitable — beaches disappear. Add human interference with natural beach topography — channel dredging, sand replacement, seawalls, jetties — and it’s a recipe for disaster. Here are 10 notable beaches in need of saving. Does sand look and feel the same wherever you go? “The sand on […]
What has the greatest effect on plate movement?
What has the greatest effect on plate movement? Scientists still debate over which of these forces has the greatest effect on plate motion. Convection currents in the mantle produce a force that causes motion called basal drag. Rising mantle material at mid-ocean ridges creates the potential for plates to move away from the ridge with […]
Are houses wired in series or parallel?
Are houses wired in series or parallel? Most standard 120-volt household circuits in your home are (or should be) parallel circuits. Outlets, switches, and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit. […]

How strong of a magnet Do I need to magnet fish?
How strong of a magnet Do I need to magnet fish? Pulling force of at least 500lbs (226kg) If you’re just starting out, start with a 500lbs capable magnet. This will satisfy the majority of hauls without feeling like you’re missing out. 500lbs is still a very strong magnet. If you want to get any […]
What is the function of base course?
What is the function of base course? Under rigid pavements, the base course is used to: (1) provide uniform and stable support, (2) minimize damaging effects of frost action, (3) provide drainage, (4) prevent pumping of fine-grained soils at joints, (5) prevent volume change of the subgrade, (5) increase structural capacity of the pavement, and […]

Does humidity depend on temperature?
Does humidity depend on temperature? Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher humidity in cool air than warm air. Relative humidity, expressed as a percentage, indicates a present state of absolute humidity relative to a maximum humidity given the same temperature. […]
What affects the rate of heat transfer?
What affects the rate of heat transfer? Factors that affect rate of heat flow include the conductivity of the material, temperature difference across the material, thickness of the material, and area of the material. Different materials have greater or lesser resistance to heat transfer, making them better insulators or better conductors. How can you increase […]
