Theodore Roosevelt's foreign policy is often referred to as Big Stick diplomacy. This moniker, though simple, in essence summarizes Roosevelt's views on international relatiâ¦ons; he viewed it as imperative that the United States speak softly and carry a big stick..
About 90 percent of the surface of Venus appears to be recently solidified basalt lava; it is thought that the planet was completely resurfaced by volcanic activity 300 million to 500 million years ago.enus is covered by a thick, rapidly spinning atmosphere, creating a scorched world with temperatures hot enough to melt lead and a surface pressure 90 times that of Earth. Because of its proximity to Earth and the way its clouds reflect sunlight, Venus appears to be the brightest planet in the sky.
However, spacecraft have discovered significant differences as well. For example, Venus' rotation (east to west) is retrograde (backward) compared to the west-to-east spin of Earth and most of the other planets. Approximately 96.5 percent of Venus' atmosphere (95 times as dense as Earth's) is carbon dioxide. The principal constituent of Earth's atmosphere is nitrogen. Venus' atmosphere acts like a greenhouse, permitting solar radiation to reach the surface but trapping the heat that would ordinarily be radiated back into space.
