What happens to relative humidity when the temperature rises? What happens when a plant doesn't get enough oxygen? What happens when hot and cold air meet? When air expands, what happens to the air temperature? What happens to the nitrogen we inhale? What would most likely happen if there ...
known as fracking—created a second U.S. energy boom, largely decreasing OPEC’s importance and influence.9Heavy reliance on fossil fuels is cited as one of the main causes of global warming, a topic that has gained traction in the past several decades.10Risks surrounding oil drilling include...
It includes what happens while something is in use. And it considers the final disposal or reuse of things. Even though raw materials are the first step, in fact there are raw materials added in at every single step along the journey. For money, raw materials go into each step of ...
【推荐1】Many scientists say that the world is getting hotter and hotter. If they are right, the ice at the North and South Pole will melt eventually. If this happens, the sea level will___and may cover most___all of Singapore. This will force everybody to move to a___country. We...
For instance, when an asteroid hits the earth, intense heat and pressure develop. The heat and pressure cause changes in the rocks where the comet hit. One of these changes is shock-fractured quartz grains. Bits of quartz (a common mineral in the earth's crust) will break in an unusual...
The term net-zero carbon (or net-zero carbon emissions) defines what happens when people balance the amount of greenhouse gases (GHG) they emit with the amount they remove. Essentially, it’s a way to avoid adding more carbon into the atmosphere while still being able to use it at the ...
If seawater salinity increases, what happens to the density? Water Bodies: In the context of earth science, a water body can be defined as any natural accumulation of water present on the surface layer of the planet. The size and depth of the water body vary greatly, and in terms of wat...
s to separate. Lightning can strike during a snowstorm when the charge needs to be equalized, just like in a summer thunderstorm. These conditions don’t happen often in winter, which makes thundersnow rare. And since snow dampens sound, thunder may be hard to hear even when it happens....
The electrons take in the energy of the light wave and start to vibrate. What happens next depends upon how tightly the atoms hold on to their electrons. Absorption occurs when the electrons are held tightly, and they pass the vibrations along to the nuclei of the atoms. This makes the ...
The process of capturing the neutron and splitting happens very quickly, on the order of picoseconds (0.000000000001 seconds). In order for these properties of U-235 to work, a sample of uranium must beenriched; that is the amount of U-235 in a sample must be increasedbeyond naturally occur...
