Why is sediment transport important? Sediment transport is applied to solve many environmental, geotechnical, and geological problems. Measuring or quantifying sediment transport or erosion is therefore important for coastal engineering. Movement of sediment is important in providing habitat for fish and other organisms in rivers. What are two ways water transports sediment? How do rivers […]

How do emotions affect our perception? Emotional arousal guides attention so that people’s attention tends to be drawn to objects that are arousing. As we shall see, some of the important influences of emotion on perception are mediated by attention, but emotion can also influence pre-attentive perceptual processes. How do emotions affect reality? Emotions drive […]
Can dogs drink water from a dehumidifier?
Can dogs drink water from a dehumidifier? Would it be safe to use the water I take from my dehumidifier and give it to my pets? No. The typical collection tank from a residential dehumidifier is not a safe source of potable water, and certainly isn’t up to the quality of commercially-distilled water. Is it […]
What force causes current to flow?
What force causes current to flow? Electric current is flow of electrons in a conductor. The force required to make current flow through a conductor is called voltage and potential is the other term of voltage. For example, the first element has more positive charges, so it has higher potential. What’s the minimum voltage at […]
Will Vinegar float on water?
Will Vinegar float on water? They don’t mix in water and will float. Household vinegar consists almost entirely of water, but with some acetic acid molecules dissolved in it. Is isopropyl alcohol heavier than water? This means that water and isopropyl alcohol must have different densities and that the water is more dense than isopropyl […]
What role does carbon dioxide play in photosynthesis?
What role does carbon dioxide play in photosynthesis? The carbon dioxide enters the leaves of the plant through small pores called stomata. The plant uses sunlight as energy to perform this chemical reaction. Photosynthesis separates carbon dioxide and water — known as CO2 and H2O, respectively — into their individual molecules and combines them into […]
Do tents attract lightning?
Do tents attract lightning? Tents alone don’t attract lightning, but that doesn’t mean they’re safe during a thunderstorm. The possibility for a tent to get struck by lightning is increased by the campsite location and adjacent tall objects. What happens if lightning hits a tent? If a lightning bolt hits a tent the energy will […]
What happens when a big star collapses?
What happens when a big star collapses? The outer layers of the star will be ejected into space in a supernova explosion, leaving behind a collapsed star called a neutron star. Ordinary matter, the kind that we and everything around us is made of, is mostly empty. It is made up of atoms, which are […]
Is Dove soap made with lye?
