According to the Federal Highway Administration, there are 46,876 miles of interstate highway in the United States. The Interstate System was built with funds allocated to each state by a series of acts of Congress.
A:Asia is the largest continent and has the longest coastline of all the continents. Asia has a total area of approximately 17.2 million square miles and a coastline stretching 39,022 miles. Asia is bordered by the Pacific Ocean, the Indian Ocean and the Arctic Ocean.
A:A satellite image is an image of the whole or part of the earth taken using artificial satellites. These images have a variety of uses, including: cartography, military intelligence and meteorology. Satellite images can either be visible light images, water vapor images or infrared images.
A:According to the World Atlas, parts of Antarctica, Australia, the southern islands of Asia and the southern part of Africa are in both the Eastern and Southern Hemispheres. A number of large islands are in both hemispheres as well, including Madagascar and New Guinea.
A:It is impossible to give an exact figure regarding the number of mountains in the world. There are hundreds of mountains on land and under the sea. There are very few mountain ranges that are very tall and that have a permanent snow cover. The Alps in Europe, the Himalayas in Asia, the Andes in South America and the Rockies and Appalachian mountains in North America are well-known mountain ranges.
A:The Mississippi River flows through just one country: the United States. Beginning at Lake Itasca in Minnesota, the river winds its way over 2000 miles through the center of the country before emptying into the Gulf of Mexico.
A:In order for an area to be considered a state, it must have a permanent population, a defined territory, a government and sovereignty. If just one of these is missing, an area will not be given statehood.
A:There are seven continents: North America, South America, Europe, Asia, Africa, Australia and Antarctica. The Oceania region is sometimes associated with Australia, but this group of land masses is not actually a continent.
A:There are 33 major deserts in the world that, when subdivided into smaller deserts, similar to mountain ranges, equal 71. Of those 71, 12 are in Africa, one is Antarctica, three are in the arctic basin, 26 are in Asia (including the Middle East), 10 are in Australia and New Zealand, 10 are in Europe, four are in North America, and five are in South America.
A:In geography, aspect denotes the compass direction in which the slope of a mountain faces. Aspect also describes flat land and refers to the direction one section of land faces with respect to another section. For example, a coastline has a westerly aspect if the sea is on the west.
A:For those studying geography, the term relief refers to the horizontal and vertical dimensions of land surface, also known as terrain. This is particularly apparent on physical maps, which emphasize the relative height of the land with differences in color and shading for differences in height, often resembling three-dimensional surfaces, instead of emphasizing geographical boundaries of states and countries.
A:Continents in the Western Hemisphere include all of South America, almost all of North America, and parts of Europe, Africa and Antarctica. The world is divided into four hemispheres: the Northern, Southern, Western and Eastern.
A:In geography, spatial distribution refers to how resources, activities, human demographics or features of the landscape are arranged across the surface of the Earth. It is the physical location of salient features of a place.
A:When the North Star (Polaris) appears 5 degrees above the horizon, it means that the observer is 5 degrees latitude north of the equator. Polaris is as many degrees above the northern horizon as the observer's latitude above the equator; at the North Pole (90 N), it is directly overhead.
A:Cold deserts are deserts that experience low temperatures and long winters. They occur in the Arctic, the Antarctic and Greenland, as well as above the tree lines of mountain ranges. Average temperatures range from 28 to 39 degrees Fahrenheit in winter and 70 to 79 degrees in summer.
A:The South Pole is the southernmost point on Earth's surface and is located in Antarctica at 90 degrees south latitude. Due to the extreme location of the South Pole, the sun shines 24 hours per day during the summer and is never visible during the winter.
