Science: Chapter 5 Lesson 1 Earth

This is a kind of landform that is a narrow, steep-walled, and deep valley with or without a perennial stream at the bottom. It is larger than, but otherwise similar to, a gorge.

These are landforms higher than the surrounding areas. They are formed due to the tectonic movements, earthquakes, volcanic eruptions and erosion of the surrounding areas caused due to wind, water and ice.

These are flat highlands that are separated from the surroundings due to steep slopes. They are formed by collisions of tectonic plates, magma action that causes the elevation in earth’s crust.

These are low-lying areas of land between hills and mountains that are formed due to the actions of glaciers and rivers over millions of years.

Due to lack of adequate rainfall, it is a dry piece of land with little or no vegetation. They are mostly found mainly in rain shadow areas which are leeward of a mountain range with respect to the wind direction. The atmospheric air is very dry, and daytime temperature is high.

It is a piece of land which is surrounded by water from all sides and formed either due to volcanic eruptions or due to hot spots in the lithosphere.

These are flat or the low relief areas on the surface of the earth. It might be formed as a result of the sedimentation of eroded soil from the top of the hills and mountains or might be due to flowing lava deposited by the agents of wind, water, and ice.

These are natural flowing streams of fresh water descending from mountains.

The biggest water bodies found on earth and are saline in nature.

These are large land areas that extend into water bodies. They remain surrounded by water on three sides.
