False (apex)
True
False. While color can sometimes be a helpful characteristic in identifying a mineral, it is not always the most reliable. Other properties like hardness, luster, cleavage, and specific gravity are generally more reliable for identifying minerals.
Earth's north magnetic pole is the point on Earth where the planet's magnetic field points vertically downwards. It is currently drifting towards Russia at a rate of about 10 kilometers per year. This pole is different from the geographic North Pole, which is the point where Earth's axis of rotation intersects its surface.
What you are calling a theory is based on a single testable observation. That makes it an hypothesis. A theory wants to collect up a variety of related hypotheses and derive a grand answer to why a system works the way it does.An hypothesis must be testable by empirical means and it must be provable false. If you fail to prove it false, you can accept it. That doesn't make it true, though.Now that we've reduced Aristotle's contention to an hypothesis, you must recognize that an hypothesis can never proven true. You can only support it. You can prove the hypothesis "A plant gains weight by obtaining material from the soil." false. if you weigh the dry soil before and after and find that the weight didn't change, the hypothesis is false.If the weight after was the same, you might postulate that the plant is getting its mass from the air and the water (new hypothesis). If you repeat the experiment a number of times and it always results in the same result, that gives greater support but it never makes it true.
Our planet behaves as though a giant bar magnet is buried deep within the earth, and lying slightly out of alignment with the earth's axis of rotation. The points where this imaginary bar magnet's magnetic field lies perpendicular to the earth are named Magnetic North and Magnetic South respectively. These points do not coincide with the earth's geographic poles, which are called True North and True South respectively. It's very important to understand that 'Magnetic North' and 'Magnetic South' describe locations, and have nothing whatsoever to do with their magnetic polarities. In fact, these locations are not fixed, but constantly move relative to True North and True South, and the locations must be taken into consideration for the purpose of navigation.A freely-suspended magnet (or a compass needle) will align itself with the earth's magnetic field and will always come to rest pointing in a Magnetic North - Magnetic South direction. Because of this, one end of the magnet was originally named its 'North-Seeking Pole', while the other end was named its 'South-Seeking Pole'. Over time, we have dropped the word 'seeking' from these expressions, and now call the ends of a magnet (or compass needle) its 'north pole' and its 'south pole' which, by common consent, are used to identify the magnetic polarities of a magnet. Because 'unlike poles attract', this means that the magnetic polarity of Magnetic North (i.e. the location) must be a south pole, and the magnetic polarity of Magnetic South must be a north pole.To summarise, the terms 'Magnetic North' and 'Magnetic South' are locations so-named to differentiate them from 'True North' and 'True South' for the purpose of navigation. Because the north pole of a magnet or compass needle is attracted towards Magnetic North, that location's magnetic polarity is south. And, of course, the magnetic polarity of Magnetic South location is north.From geological records obtained from magnetized rock strata and other natural materials, it is well-known that the magnetic poles have actually "flipped over" several times during the many aeons of the earth's long history (although not during man's existence). Should this do so again in the future, it will have no affect whatsoever on the locations or on naming of 'Magnetic North' and 'Magnetic South', although their magnetic polarities will, of course, reverse!For more information see the Related links shown below.
Yes. (True)
False
no its false
true i think
False. When solving for the slope of the best fit line, you should consider all data points in your dataset to find the line that best fits the overall trend. Choosing points closest to the line or on the line may bias your results and not accurately represent the relationship between the variables.
