Answer 1

If you were to look down at the plane of the solar system from its 'north pole' you would see the planets orbiting the Sun counter clockwise, and rotating on their axis counterclockwise. Except for Venus. Venus would be rotating clockwise as it orbited the Sun counterclockwise. Venus is not alone. The axis of Uranus is inclined so far towards the plane of the solar system that it almost rolls on its side as it orbits the Sun.

It is a curious fact that as Venus rotates three times on its axis in 729.27 days, the Earth goes twice around the Sun ( 728.50 days) This has suggested to many dynamicists that Earth and Venus are locked into a 3:2 tidal resonance. There are many bodies in the solar system that seem to be locked into various kinds of spin-orbit resonances, especially families of asteroids with the planet Jupiter. Mercury also seems to be gravitationally locked into some kind of resonance with the Sun since its day (58.646 days) and its year ( 87.969 days) are also in the proportion of 3:2.

Forces acting on spinning bodies result in some peculiar acrobatics. For instance, if you take a spinning top and give it a push, it will begin to wobble in a manner called precession. The axis of the Earth makes a 26,000 year wobble with an amplitude of tens of degrees. This is all due to the influence of the Moon's tidal attraction of the Earth. In the case of Venus, however, the gentle gravitational forces it may receive over billions of years to place it in a 3:2 resonance with the Earth don't seem to be strong enough to tip the entire planet over to make its rotation retrograde.

The best, current, ideas still favor some dramatic event that occurred while Venus ( and Uranus for that matter) were being formed. It is known from the cratering evidence we see on a variety of planetary surfaces, that soon after the planets were formed, there were still some might large mini-planets orbiting the Sun. One of these may have collided with the Earth, dredging up material that later solidified into our Moon. The satellites of the outer planets are probably representitives of this ancient population of bodies. Venus may have experienced an encounter with one of these large bodies in which, unlike for the Earth, the material didn't form a separate moon, but was absorbed into the body of Venus. In addition to mass and kinetic energy, this body would also have contributed angular momentum. The result is that the new spin direction and speed for Venus was seriously altered from its initial state which could have been very Earth-like. Today, the result of that last, ancient collision is Venus with a retrograde rotation.

This theory may also apply to Uranus provided that the collision happened before the 15 satellites themselves were captured or formed. Their orbital planes look very uniform and show no evidence for a dramatic gravitational event such as a collision. It may be, too, that the Uranian collision event dredged up matter and flung it into orbit around Uranus, and out of this were formed the larger moons of Uranus.

According to the above article, it sounds like (e) all of the above.

Answer 2

Are you serious? Is this a real homework question? Who is your teacher? Only creationist liars and frauds refer to anyone at all as an "Evolutionist," or would refer to any physical process as "unexplainable."

Answer 3

very few could desire to have examine this questions and intensely few replied it although i'm additionally between them a citizen of united statesa. in the past an Indian as we won't be able to stay a citizen of two international locations because of the fact being American resident we aren't to any extent further Indian yet we are in a position to flow to our mom land for ever and are unfastened to stay there too loosing all reward if we are residing longer i think of , each physique loves peace and hate a place the place there isn't any risk-free practices . once I see terrorism is a worldwide project each physique ought to play his or her place . while Malala a muslim female can combat for training of women ,while a infant needs his or her freedom a terrorist lives in terror and not unfastened from its effects ,an afternoon could come while human beings could come forward to wipe it from human minds even with the indisputable fact that it particularly is purely too overdue already , there are this way of great variety of potential of destruction to wipe entire humanity if needed action isn't taken faster . i'm too small to take any action ,yet all style of violent movies ought to be removed from media so as that we don't have get admission to to them via any potential . human beings can lease those varieties of movies for couple greenbacks and upward thrust as much as combat with family members then to subsequent neighbor then at artwork then someplace at procuring mall ,then anyplace he does now not think of top led to with the help of media and materials he can get admission to from cafes and action picture star dollar who supply this freedom so particularly . Then we attempt to calm the recommendations this is already bombarded with lots detrimental strategies worldwide huge .

Answer 4

e) None of the above.

The study of biological diversification has nothing to do with planetary formation.
