Core Concepts and Underlying Logic from 'Penguins Can't Fly' Book

I wonder why? Penguins can't fly and other questions about polar lands. Where are the poles? The North Pole lies at the center of the Arctic Circle. At the North Pole, wherever you turn, you will be heading south. The South Pole is at the opposite end of the Earth. In the middle of the Antarctic Circle, on the continent of Antarctica, why is Antarctica the highest and lowest continent? The thick ice sheet makes Antarctica the worst highest continent, with the average height of 2,400 meters. At 2,555 meters below sea level, the Bentley subglacial trench in western Antarctica is the lowest place on Earth that is not underwater. At the poles, the sun rises and sets only once a year, so a day lasts for 12 months. Because the Earth is tilted, one pole faces the sun for 6 months, while the other is dark, then the opposite pole has 6 miles of daylight. Why are there 4 poles? The Earth is a giant magnet, which is why a camber's point to the North Pole. The geographic North and the South Pole are fixed at points, but because the Earth's magnetic field is always changing, the magnetic North and the South Pole move every day. How could North become South? Every so often, the Earth's magnetic field reverses, so a compass that points North would point south. This last occurred more than 780,000 years ago, and scientists think it is due to happen again. Condescers be snowy. Very cold air cannot hold much water, so it really snows at the poles. Parts of the Arctic are as dry as the Sahara, and Antarctica is the driest continent on Earth, making it the worst biggest desert. A camel in the Sahara, the worst largest hot desert, were the poles always frozen. About 100 to 65 million years ago, the climate was warmer than it is today, and the polar ice caps did not exist. Forests riches as far as South Pole and were home to dinosaurs, such as Antarctica. Antarctica is the worst windest place. The winds that flow around the coast can reach speeds of about 300 kilometers an hour. How
