What are the causes of convection current? Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. Where can convection currents […]
Is 19 km/h wind strong?
Why is evaporation important how can it help you?
Why is evaporation important how can it help you? The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle. Heat from the sun, or solar energy, powers the evaporation process. Once water evaporates, it also helps form […]
What are three types of models?
What are three types of models? Contemporary scientific practice employs at least three major categories of models: concrete models, mathematical models, and computational models. What is simple model? A Simple Model exists to make the skill set required to build financial models more accessible. The intention is to create simple material and facilitate the learning […]
Is it safe to swim to a sandbar?
What is the very first step in the proton-proton cycle?
What is the very first step in the proton-proton cycle? The first step in this process is the collision of two protons where proximity permits the strong nuclear force to bind them together. The resulting combination is not stable, and one of the protons will decay to become a neutron, and this forms a stable […]
How much force does a falling person have?
How much force does a falling person have? OSHA limits the amount of force that a person should experience during a fall to 1,800 pounds. Forces greater than this can result in internal bleeding, damage, or death. When a personal fall arrest system is used, a shock-absorbing lanyard or fall limiter is the only way […]
How do you determine instantaneous speed?
How do you determine instantaneous speed? Instantaneous speed is found by taking the absolute value of instantaneous velocity, and it is always positive. Average speed is total distance traveled divided by elapsed time. The slope of a position-versus-time graph at a specific time gives instantaneous velocity at that time. What does instantaneous rest mean? It […]

Copper has the ground-state electronic configuration [Ar]4s1 3d10. It has two commonly observed ions, Cu+ and Cu2+. Cu+ has the ground-state electronic configuration [Ar]3d10. What is the Unabbreviated […]
Could we survive on earth without the greenhouse effect quizlet?
Could we survive on earth without the greenhouse effect quizlet? What is the greenhouse effect? No we would not be able to survive because without these gases, the Earth would be too cold for humans, plants and other creatures to live. The two largest greenhouse gases are Co2 and methane which comes from fossil fuels […]
