Rain and Flooding
Rain is a type of precipitation which is readily absorbed by the ground. However, flooding might occur if there is a downpour or heavy rain. Flooding can result in damage to property, illness and even death.

Asked in The Bible, Rain and Flooding, Old Testament
How many times did God flood the earth?
Once. There is only one story of God's flood of waters upon the earth, and when it was over, he pronounced in Genesis 9.11. "And I will establish my covenant with you; neither shall all flesh be cut off any more by the waters of a flood; neither shall there any more be a flood to destroy the earth."

What is the difference between chemical and mechanical weathering?
Mechanical (physical) weathering is the breakdown of rock into smaller particles due to such factors as freezing and thawing, release of pressure, water absorption, salt crystal formation, landmass uplift, expansion and contraction from the sun or fire, plant root growth, actions of animals, abrasion, or other means that do not directly affect the rock's chemistry. Chemical weathering is the dissolution, carbonation, oxidation, or hydrolysis of rock and mineral by chemical means only, mostly from reactions with water or the acids contained in rainwater. Other materials are formed in the process. Warm, tropical climates are ideal environments for chemical weathering to take place as the chemical reactions are quickened by the bountiful rain and warm temperatures.

Where does Earth's water come from?
Condensing water vapor, augmented by ice and liquid water delivered by asteroids and the larger proto-planets, comets, and trans-Neptunian objects produced the oceans. -wikipedia Earth and other planets started as a bunch of left over debris from dead stars: iron, nickel, carbon. Just to name a few. A star forms from collapsing hydrogen clouds which will create a swirling motion naturally. Eventually the young star will eat all the buoyant hydrogen and spin all the heavy metals surrounding it. This debris of metals and other elements will eventually collided with each other to form globs of collected material or rocks. As these rocks continue to grow with each collision eventually it will start to bend it's boundaries which promotes a stronger force of gravity. Gravity naturally pulls objects to its center, this is why the planet are round, and anything that tries to over exceed the boundaries of gravity will collapse. To summarize, a giant rocky ball composed of space leftovers is now rotating an object more massive than its self, a skeletal earth is born. The law of gravity forced the earth to pull what its made of to its center. This law creates friction and pressure within the earth. With this friction and pressure comes heat. This heat will eventually melt the contents of the skeletal earth, remember (nickel, carbon, iron, there are lots more). [Lava is now created.] With everything molton, the heaviest stuff went to the center (mostly iron). And the lightest material stayed on the outter portion. With time the out side of the skeletal earth will form a cool rocky crust as it moves through its elpise around our star, the sun. Earth rotates because of a jolly good whack, the one that kicked off the (mass that made up the) moon. The earth now has a cooled crust and hot lava flowing below it, this creates volcanoes! Volcanoes have very narrow pockets in the sides of the moutain which allow the lava to shoot out creating more rocks and eventually water! Over lots and lots of time more crust is layered upon it self. Causing cooler rocks which will eventually form condensation within their pores. If you have ever seen a lava rock the pores are very apparent, the pores are created from the exsolution of gasses in the lava as it is cooling. This process is more likely to occur at the north and south poles. Everybody knows the poles of the earth are cooler and the equator is warmer. The colder it gets at the poles the more of a chance condensation will occur. As this cycle repeats through years of seasons, which still exist without water. The seasons are caused by the tilt of the Earth's axis (about 23 degrees off vertical) caused by that same great whack. So this creates a cold and hot seasons which are experience through out the entire earth. The condensation within the pores of lava rocks will eventually freeze then melt then pool. With pooled water at the poles it only has three places to go, 1: freeze 2:drip or stream somewhere else or 3: evaporate into the atmosphere, which creates clouds! Which transfers water! which causes rain! which cause more pooling on other regions of the earth and with time; oceans, polar ice caps, violent wet weather and life. At some early point in time (after the moon) the Earth was a hot, glowing ball which would have out-gassed fairly completely. Hydrogen is light enough so that most of it would have escaped, and the was little or no oxygen. (At least no un-bound oxygen.) It's thought that since comets are mainly ice, they would have hit the Earth and brought most, if not all, the water we now have. As far as I understand it, the presence of water is a natural occurence due to the presence of the elements of hydrogen and oxygen on this planet. The comets did not bring the majority of Earth's water to the planet, although many comets are covered and/or filled with ice, most of that would burn off in entrance into the atmosphere and become a part of our natural water cycle. As the proximity to the sun heated the earth, hydrogen and oxygen began to move about (as atoms do under the influence of heat) these molecules bond very easily and readily, almost as if they want to. So when the hydrogen and oxygen that were already a part of this planet began to move (or just as a natural occurence of their constant state of movement) they began to come together to form the H2O molecule that is the smallest possible amount of water. As you know by observation, water tends to pool...so it collected into larger bodies, including groundwater and lakes, and gravity created rivers which stream from these sources whenever there is too much for the given recepticle. One of the 2 previous posters accurately described much of the water cycle, so i feel no need to go further into it. But anyone who says that comets brought the majority of our water to this planet is sorely mistaken, misinformed, or simply trying to cause confusion for confusion's sake. The trouble with this argument is that while hydrogen was origally plentiful, the wasn't much (or any) free oxygen (all the bound oxygen was in the rocks - which is still there). And free Hydrogen is lost from a planet as small as Earth, it takes the outer gas giants to hold it. The answer above is "very good" but lacking in some small ways: that will change the total outcome of the problem. The earth was a sun, that existed before our sun (I don't know why this is important: but the writer of original answer here might) and our planet (the cooling sun) began to cool and lose strength (maybe due to our sun's growth and thus staving its food supply: not allowing this planet (once a sun) to live and grow) and formed vast amounts of water around its mantel: from the hydrogen in the universe and the oxygen created in the dying sun's (our earth) nuclear reactions. The following was copied from http://curious.astro.cornell.edu/question.php?number=195 and it is proof of the theoretical soundness of my previously mentioned statements; it is written by Dave Kornreich: "No, H20 cannot exist in stars, but H and O separately can. Hydrogen is the basic building material of the universe, created in the Big Bang. Oxygen is created by nuclear reactions in stars. If you put H and O together in the cold of space, you get H2O. There are enourmous amounts of water in space. In fact, nearly all of the oxygen in space is in the form of water or carbon monoxide. Similarly, most the carbon and nitrogen in space are also in their most hydorgenated forms: methane (CH4) and ammonia (NH3)".
How do you make acid rain for a science experiment?
First if you get vinegar and put it in a bottle for 3 days it will turn into carbon dioxide.(d2) After the three days are over,pour water in it let it stay and dissolve in with the carbon d2. Then you get acid rain. If you cannot do that just get algea(or moss) and fertilizer and mix it with WARM water. Let it sit for a couple of hours. How much vinegar/water combination do you use? Is the bottle supposed to be sealed or not. NOT SO Acid rian is due prmarily to the interaction of SO2 and NO2 with moisture in the air, acetic acid has nothing to do with it,further more vinegar does not turn into CO2. the gas phase sulfur dioxide is oxidized by reaction with the hydroxyl radical via an intermolecular reaction : SO2 + OH· → HOSO2· which is followed by: HOSO2· + O2 → HO2· + SO3 In the presence of water, sulfur trioxide (SO3) is converted rapidly to sulfuric acid: SO3 (g) + H2O (l) → H2SO4 (l) Nitrogen dioxide reacts with OH to form nitric acid: NO2 + OH· → HNO3

Asked by Khalid Waters in Science, Rain and Flooding, Clouds, Weight and Mass
How much do clouds weigh?
To calculate the weight of a cloud, you first have to figure out how dense it is. The average density of a cumulus cloud is around half a gram of water per cubic meter. Second, you need to determine how big the cloud is, presumably by measuring its shadow while the sun is above it. A typical cloud is about a kilometer across and roughly cube shaped, meaning it has a volume of one billion cubic meters. Using this formula, scientists have determined that the average cumulus cloud weighs around 1.1 million pounds.
Construction and theory of rain alarm?
There are many common moisture & water detectors readily available. They work like this: 2 conductors are placed close together but aren't touching. When water (which is electrically conductive, but not as conductive as most people think) contacts the conductors, the circuit is completed, and whatever is designed to happen next, happens. It could be an alarm, light, or a signal to an overall supervisory system such as in a factory basement, or tunnel.

Asked in Rain and Flooding, South Africa
Does it rain much in South Africa?
In South Africa Rainfall depends upon the region. Starting from South the Cape Province has a Mediterranean type of climate and rains during Winter season ( May/June/July/August ) and the average rain is normal . In the desert regions like Karroo rains very little. In the Qua-Zulu Natal there is more than enough rain and the region is normally very green. In the Johannesburg/ Pretoria region that is the financial heartland of South Africa rains mainly in Summer ( November/December/January/February) and the rain is normally average . This is a Subtropical climate. In general South Africa has less rainfall to satisfy the needs of the country. With the warming of the Globe rain fall patterns started changing for the worst. I hope a weather expert can give more details.
Asked in Rain and Flooding
Is it going to flood in Ipswich?
Ipswich, west of Brisbane, Queensland is prone to flooding when there is a major rainfall event. Ipswich has undergone extensive flooding - firstly in 1974, when Brisbane also went under, and again in January 2011. In the most recent event of 2011, the massive Wivenhoe Dam west of Ipswich exceeded 180% capacity, meaning water had to released into the Brisbane River large volumes, equivalent to several Sydney Harbours. This, of course, had a flow-on effect for the Bremer River in Ipswich. In major rainfall events such as these, lower areas of Ipswich are most definitely under threat, but even people who are not in the usual low-lying regions should take whatever precautions they can. All the water coming down from the Brisbane Valley and Lockyer Valley has to go somewhere, and the Bremer River in Ipswich is easily swollen.
