Does the water in a bath or sink go a different way down the drain depending on which hemispere you are in?

Water spiraling down a drain

Yes the water will drain in different directions depending on which hemisphere you’re in.   Usually this question is asked about toilet flushing, but I guess it’s still fun to answer even though you’re more interested in baths and sinks draining. Water will drain in different directions depending on the hemisphere due to the Coriolis force, […]

Does the Earth currently weigh more than it did when it was first formed?


This is one of those questions that really doesn’t have a correct answer.  The Earth really doesn’t have a weight at all.  Weight is the measurement of the gravitational pull of one object on another.  Most objects are too small to consider, like you and me, or the keyboard I’m typing on, but the Earth […]

Why do the earth’s oceans appear blue from the moon?


The earth’s oceans and sky both appear blue to everyone who observes them. They do this because water absorbs blue light less strongly than it absorbs other colors. When ocean water is exposed to sunlight (white light), it absorbs most of the red light quickly and a good fraction of the green light. But the […]

How many days would it take the earth to travel around the sun if it traveled at the speed that the moon revolves around the earth?


It takes twenty-eight days for the moon to travel around the earth.  To calculate the speed the moon travels we must figure out what distance the moon travels in those 28 days, or the circumference of the circle the moon travels.  The formula to calculate the circumference of a circle is Pi(d) (the moon does […]

How much does a cloud weigh?


A tough question to answer since clouds come in many different shapes and sizes.  On some days I look up at the sky and see nothing but cloud in every direction, I’m scared to think how much those clouds weigh, so I’ll just talk about the nice fluffy clouds we see on nice summer days, […]

How old is planet earth?


In the very beginning of earth’s history, this planet was a giant, red hot, roiling, boiling sea of molten rock – a magma ocean. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. As the […]

What is the source of heat?


We get the majority of our heat from the sun.  The next largest source is the core of the Earth itself.  Then there’s a billion way tie for the third biggest source of heat. Heat itself is the motion of atoms, molecules and other particles.  The faster it’s moving the hotter it is.  Think of […]

How many cycles are there in the water cycle?

Water Wave

The water cycle itself is one cycle and water is continually cycling itself. Perhaps you are referring to the number of stages in the water cycle.  For that, the answer is four. Evaporation, Condensation, Precipitation, Collection. As the water evaporates, vapors rise and condense into clouds. The clouds are blown over land, and precipitation falls […]

Why are there no earthquakes deeper than 670 kilometers?


Earthquakes are movements of the Earth’s surface.  The lithosphere, or the Earth’s crust, is only about forty kilometers think.  The mantle is the next major layer and it is around twenty-five hundred kilometers thick.  Surly there is movement below the mantle and below six hundred and seventy kilometers; they’re just not considered earthquakes as they are […]

How long does it take for light from the sun to reach the Earth?


Light travels at a speed of 1.08 billion kilometers an hour, or 18 million kilometers a minute. The sun is on average 150 million kilometers  away.  This is only an average as the Earth’s rotation in elliptical, it is closer to the sun at certain times of the year and farther away at other times of the […]
