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.
5. Snow on Venus? Venus Express discovered a surprisingly cold region high in the planet's atmosphere, where conditions may be frigid enough for carbon dioxide to freeze out as ice or snow. Although the planet's surface is like a red hot furnace, conditions are very different at an altitude of 125 km, where Venus Express revealed a very frigid layer with a temperature of around -175Â°C. The unexpected cold layer is far chillier than any part of Earth's atmosphere, despite Venus being much closer to the Sun. The discovery was made by studying light from the Sun as it passed through the atmosphere, revealing the concentration of carbon dioxide gas molecules at various altitudes along the terminator â the dividing line between the day and night sides of the planet.
