Test: World- Physical - SSC CGL MCQ

Contour lines on a world physical map represent the elevation and shape of the land. Plateaus, which are elevated flatlands, are often depicted using contour lines.

Mountains are represented on the map using contour lines that show the elevation and shape of the land. Contour lines help visualize the varying heights and slopes of mountain ranges.

A plain refers to a vast area of flat or gently sloping land. The Deccan Plateau in India is an example of a plain, characterized by its relatively flat terrain.

Lakes are depicted as blue or shaded areas on a world physical map. This coloring helps differentiate them from other geographical features and indicates their water presence.

Deserts, characterized by arid conditions, are typically represented on a world physical map using light brown or yellow colors. This coloring signifies the sandy or rocky terrain found in deserts.

The continental shelf refers to the submerged area of each continent extending into the ocean. It is often marked on a world physical map with a light blue color.

Deep ocean trenches, depicted as dark blue or contour lines, indicate subduction zones where one tectonic plate is forced beneath another. These areas are associated with seismic activity and often located in proximity to volcanic activity.

Active and prominent volcanoes are often marked on a world physical map with triangle symbols. The symbols usually include labels indicating the volcano's name and height.

Latitude and longitude lines on a world physical map form a grid system that provides a precise location reference. By using these coordinates, one can pinpoint specific points on the Earth's surface accurately.
