In astronomy, geography, and related sciences and contexts, a direction or plane passing by a given point is said to be vertical if it contains the local gravity direction at that point. Conversely, a direction or plane is said to be horizontal if it is perpendicular to the vertical directio...
The latitude 23° 26′ North is also known as theTropic of Cancer. It marks the northern-most position on the Earth, where the Sun is directly overhead at least once a year. This happens during theJune Solstice, when the Earth’s Northern Hemisphere is tilted towards the Sun. The Tropic...
What is a scarp in geology? What does exosphere mean in geography? What is a geologic structure? What does "subduction leads to orogeny" mean? What does Pangaea mean? What is a geologic formation? How does a vertical geologic surface appear on geologic maps?
In Earth science and geography, topography plays an enormous role in describing physical features on Earth which is incredibly important for analyzing the cultural, societal, ecological, and geological impacts of various topographical variables. History The word topography itself is derived from the greek...
What is the Prime Meridian? The Earth The Earth is huge, and in order to understand where things in it are, we use a coordinate system. This system can be described as a geographic grid where latitude represents vertical (north-south) lines, and longitude represents horizontal (east-west) ...
“In geography and geology, a cliff is a vertical, or nearly vertical, rock exposure. Cliffs are formed as erosion landforms by theprocesses of weatheringand erosion. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers.” ...
Longitude lines, or meridians, are imaginary vertical lines that run from the North Pole to the South Pole. They measure the distance east or west of theprime meridian, which is set at 0° longitude and passes through Greenwich, England. Unlike latitude lines, which are parallel, longitude li...
In geography, latitude is a geographic coordinate that specifies the north–south position of a point on the Earth's surface. Latitude is an angle which ranges from 0° at the Equator to 90° at the poles. Lines of constant latitude, or parallels, run east–west as circles parallel to th...

What is the difference between Dikes and Sills? Dikes and Sills: There are various earth movements on the earth`s crust. The movements are categorized into two; vertical and horizontal movements. The movement causes the formation of various landforms such as mountains, valleys, escarpments, rift...
