In paragragh three it says "On the planet's surface, tempature's average over 800 degrees Fahrenheit, and the atmosphere pressure is 90 times greater than what we expirence on our own planet." According to the Author, this pressure would crush even a submarine fit for exploring the depths of our oceans. He also describes the events going on the surface, "erupting volcanoes, powerful earthquakes, and frequent lighting strikes" (Paragraph 3).
