What were the two major flaws of continental drift? Drawbacks of Continental Drift Theory Forces like buoyancy, tidal currents and gravity are too weak to be able to move continents. Modern theories (Plate Tectonics) accept the existence of Pangaea and related landmasses but give a very different explanation to the causes of drift. What is […]
What are the two main categories of energy?
What are the two main categories of energy? Many forms of energy exist, but they all fall into two basic categories: Potential energy. Kinetic energy. What are the 4 forms of energy? The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and […]
Can humans turn into fossil fuels?
Can humans turn into fossil fuels? Humans are animals; we’re made up of the same chemicals as those animals which decomposed into what we now call “fossil fuels”. So, yes, our remains could become oil in the far distant future. Will fossil fuels eventually run out? While fossil fuels were formed millions of years ago, […]
What is the most effective insulator?
Do rocks ever stop changing?
Do rocks ever stop changing? Does it seem to you that rocks never change? All rocks, in fact, change slowly from one type to another, again and again. The changes form a cycle, called “the rock cycle.” The way rocks change depends on various processes that are always taking place on and under the earth’s […]

Why magnets always have a north and south pole?
Why magnets always have a north and south pole? The force of a magnetic field on a particle with spin causes the particle to rotate it’s spin to align with the magnetic field. Taking these two ideas together, then, the Earth’s magnetic field will cause the magnet to align north to south. That’s why people […]
Can you reverse the direction of an electric motor?
Can you reverse the direction of an electric motor? In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the […]
