We know that the poles had changed positions in the past, because of the arrangement of the crystals in the rocks made out of metal. The crystals of the metals act like the needle of the compass when the rock is cooling off and forming, they turn into the direction of the strongest magnetic field on the Earth, which is the North Pole. So by studying the rocks that are made out of metals and see the crystals arrangement and also estimate the age of the rocks, the scientist can precisely tell how has the North Pole been moving throughout time.
<span>Mount Rainier is the highest mountain in the Cascade Range of the Pacific Northwest. This mountain was not formed in one great cataclysm but was made through many years of volcanic activity. Several volcanoes have been erupting in the region for at least 40 million years.</span>
A map is a representation of the Earth's surface. It is also a portable document describing an area. A map can also provide data such as migration trends, directions, and rock composition. There are many types of maps: The physical map shows land and water formations: mountains, oceans, rivers, the climate type shows the type of weather conditions occurring in the world, the political map shows how the earth's surface is divided into borders: continents, countries, and states... The science of making maps is referred to as cartography.
