What happens when two previously converged plates diverge?

If two tectonic plates converge to form a mountain, and the two plate then diverge, what happens to the mountain?

Is there any way to accurately test/verify the age of a living bonsai tree?

Posted: 15 Nov 2016 05:36 AM PST

I have heard of carbon dating on dead things, but never anything about living things. In bonsai i hear claims all the time that trees are "X" years old, and want to know. Is there any way to verify those claims scientifically?

Is eating fruit important, or when people say 'fruit and vegetables', are the vegetables the important part of that?

Posted: 14 Nov 2016 06:48 AM PST

I've always had a suspicion that when the government recommends you eat '5 portions of fruit and vegetables a day' or when studies show that people who eat enough fruit and vegetables live longer, they might well achieve the same result if they were only looking at vegetables. What does the evidence suggest?

In the U.S. alone, there are over 250 million cars on the road. How complicated/accurate are car keys that any key only communicates with its paired car, and vice-versa?

Posted: 14 Nov 2016 09:21 PM PST

Lets just say I have the keys to my car. Surely there has to be some other car on earth that responds to my keys, right? Are the keys and cars so precise that they can differentiate between minute differences in frequencies, or is the spectrum of car key signals simply huge. If the latter, how big is that spectrum?

How did we treat cancer in the past (pre 1900) Did we even know about it?

Posted: 14 Nov 2016 08:44 PM PST

How did we go about dealing with cancer before radiation treatment. Did we even know that cancer is what was killing some people? When did we learn it was cancer causing the deaths?

Why does old coffee stick only to the highest level in a cup?

Posted: 14 Nov 2016 04:13 PM PST

I've noticed that whenever a cup of coffee or hot chocolate is left out and cools, it always leaves behind a ring where the highest level was. Why does this happen to drinks and soups when hot but not when cold?

How Much Did the Methane Gas Leak in California Contribute to Global Warming?

Posted: 14 Nov 2016 08:07 PM PST

Was this single event large enough to significantly contribute to global warming and affect global temperature projections?

Are tectonics a prerequisite for volcanism?

Posted: 15 Nov 2016 06:39 AM PST

Can volcanism occur on celestial bodies that do not have active tectonics?

Why can an inner ear infection cause temporary taste loss?

Posted: 14 Nov 2016 07:20 PM PST

I recently had a minor inner ear infection and along with the normal slew of symptoms (headache, earache, and overall discomfort) I experienced temporary taste loss in the front half of my tongue. After some googling, I discovered that ear infection can be accompanied by taste loss (https://www.nidcd.nih.gov/health/statistics/what-numbers-mean-epidemiological-perspective-taste-smell) but I haven't yet found a source that explains why. Can anyone explain?

Are Hops plants of a particular variety essentially all cuttings/trimmings or rhizomes of one "mother-plant" many generations before?

Posted: 14 Nov 2016 08:38 PM PST

I've been reading a lot about the cultivation of Hops and have found myself uncertain of much of the biology from a practical standpoint.

Hops are most often grown from clippings or a rhizome which (presumably) is taken from a mother plant, and I have to imagine that in most cases this more or less goes back many generations. Additionally (though my understanding is admittedly limited) hops are also diecious and heterozygous which leads to an immense difficulty in selecting desirable traits and selecting others out through sexual reproduction. With this taken into consideration does this mean that any plant called a "cascade" or "brewer's gold" is basically an n-generations removed clone (for lack of a better term) of an original "prime" version of the same plant?

If not, what am I missing? How are these plants being cultivated with such similarity?

If so, is this practice commonplace in any other agricultural field on such a large scale? Are there any biological concerns with such a low rate of genetic diversity among cultivars? How much genetic diversity can/does exist across various generations of the same plant?

How much heat does the moon redirect to earth?

Posted: 14 Nov 2016 12:51 PM PST

For an average distance between the moon and the earth. Is the amount of energy transfer phase dependent? Is it proportional to the level of light received?

Do train tracks build up an electrical charge when a train approaches?

Posted: 15 Nov 2016 04:12 AM PST

I remember growing up that if you were to touch both rails as a train approached you would receive a shock

Is there any chance in any solar system, that a planet like Crematoria from the Chronicles of Riddick could exist?

Posted: 14 Nov 2016 08:18 PM PST

So this is how the planet looks. The whole idea of the planet is that it goes from chilling cold to scorching hot. The movie cites it as -300 to +700. Overlooking the fact that -300 is an impossibility, could conditions exist that allow a planet a 1000 celsius degree span between day and night?.

Did last night's supermoon cause higher tides?

Posted: 15 Nov 2016 02:35 AM PST

Apparently the moon was 7% larger (than usual? average?), which corresponds to it being 7% closer. The inverse square law for gravity suggests the Moon's pull was 14.5% higher, but I haven't heard any reports of exceptionally high tides.

Did this actually happen, or are there other factors I have overlooked?

Is there a chemical rule or pattern for what is harmful to the human body? I mean when Albert Hofmann discovered LSD how could he know he would nt die taking it?

Do we know the approximate distribution of particles in the observable universe?

Posted: 15 Nov 2016 01:27 AM PST

If we can approximate the number of baryons in the observable universe, what about the ratios of those baryons to each other? What about leptons, specifically electrons? Is there any way to estimate the number of electrons in the known universe at a given time?

How does the rate of female-on-female sexual assault compare to the rate of male-on-female sexual assault?

Posted: 15 Nov 2016 12:45 AM PST

Specifically, I'm wondering how common it is for lesbians to rape or sexually assault other women, compared to straight men.
