Some ions (particularly chloride) are toxic to plants and as the concentration of these ions increases, the plant is poisoned and dies. How do you treat salinity in water? Remember that […]
What is the commutation angle?
What is the commutation angle? The commutation period when outgoing and incoming thyristors are conducting is known as overlap period. The angular period, when both devices share conduction is known as the commutation angle or overlap angle. What is commutation inductance? The commutation process (or the overlap process) forces more than one diode or a […]
Why do we map the seafloor?
Why do we map the seafloor? High-resolution seafloor mapping is a critical tool for regulating underwater resource exploration, extraction, and equipment, allowing us to decide what and where is safe. Seafloor maps also ensure that ships are able to safely maneuver around natural – and human-made – structures on the ocean bottom. What does bathymetry […]

What are the reasons for the seasons?
What are the reasons for the seasons? As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth’s spin axis is tilted with respect to its orbital plane. This is what causes the […]
How does climate affect human behavior?
