Studying geography also teaches the physical locations and placements of territories on maps and within surrounding communities and helps students identify distances and spatial relationships of the land.Know More
Geography teaches the processes of physical and human systems and shows how they have changed the surface of the Earth in the past and present. Learning about geography also helps students learn how to make decisions that affect the environment, the surface of the Earth, and the need for global interdependence among countries throughout the world.
The study of general geography aids students in understanding global warming and climate problems, water resource issues, and political policies and decisions that affect the planet. Studies of geography also help students understand the culture of specific regions, such as the contributions of the landscape of the land, traditional food, customs, language and religion.
From a historical standpoint, geography can teach people how customs have changed throughout the years and predict how the land will be used in the future. Educators claim that the study of geography helps students become educated global citizens because it provides an understanding of how humans and industrial practices impact the planet.Learn more about Maps & Cartography

During the period of the eclipse, light from the sun passes around the Earth and through its atmosphere. This scatters the short-wavelength blue light from the sun but allows the longer-wavelength red and orange light to reach the moon.Full Answer >
