Loess are deposition of silt, with a little amount of sand and clay. They appear yellowish or brownish in color. Wind action or glacial activities are responsible for formation of loess. Glaciers are slow moving huge bodies of ice formed due to the compression of the snow layers.
They move depending on the pressure and gravity. There are two types of glaciers, the alpine glaciers which can be located in high mountains and the continental glaciers which can be located in cold Polar regions.
Peninsulas are large land areas that extend into water bodies. They remain surrounded by water on three sides. Peninsulas are formed by lithospheric movements and action of water currents. Deltas are low-lying, triangle-shaped areas, located at the mouth of rivers. In the course of creating a delta, the sand, silt, and rock particles are accumulated in a nearly triangular shape.

Plateaus Plateaus are flat highlands that are separated from the surroundings due to steep slopes. Valleys Valleys 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. Deserts Due to lack of adequate rainfall, desert is a dry piece of land with little or no vegetation. Some plateaus, such as the Colorado Plateau in the United States, still rise by a measurable distance every year.
Plateaus can also be formed by volcanic activity, when layers of lava cool and harden atop one another over time. The world's largest plateau is the Tibetan Plateau, in central Asia. This plateau stretches across nearly , square miles. Hills are elevated sections of land with notable summits that are lower and less steep than mountains. Most hills have "smoother" summits than mountains, meaning that their summits are not as severely pointed as mountaintops.
Hills are formed by the same type of tectonic activity that forms mountains. This activity, in which rocks shift upward due to colliding tectonic plates, is called faulting. Over long periods of time, faulting can turn hills into mountains.
Mountains can also become hills over time, due to severe erosion. Hills occur on every continent, in a variety of environments. Many parts of the world are famous for their rolling hills, including the highlands of Scotland and Tuscany, Italy. Maria Cook is a freelance and fiction writer from Indianapolis, Indiana.

Hills are created as a result of accumulation of rock debris or sand deposited by wind and glaciers. They can also be created by faulting when the faults go slightly upwards. Hills are generally present in low mountain valleys and plains.
The Black Hills are the most known. Human activities may also create hill when soils are dug and piled giant masses. Volcanic eruptions as well create hills after the eruption when the molten materials or lava cools and hardens in a pile. Loess is a fine-grained unstratified accumulation of clay and silt deposited by the wind. It appears brown or yellowish in color and is brought about by past glacial activity in an area.
In precise, it is sedimentary deposits of clay and silt mineral particles which take place on land in some parts of the world. Loess formed after the ice age when the glaciers covering a relatively large portion of the earth melted and was carried away, exposing the vast plains of mud.
Upon drying of the mud, the forces of wind blew away the mud and exposed sediments and eventually deposited them as silt in stacks on top of each other to create bold steep banks. Regions made of loess are witnessed in eastern China and the northwestern region of the United States.
Plains are lower than the land in their surrounding and can be found both inland and along the coast. Coastal plains rise from the seal level up to the point they meet raised landforms such as plateaus or mountains. The Atlantic Coastal plain is a prime example of a substantially populated and fertile coastal plain. On the other hand, inland plains are generally found at high altitudes. Thick forests normally flourish on plains in humid climates. A fairly large portion of plains are covered by grasslands, for instance, the Great Plains in the United States.
Human populations prefer settling on plains because of the soil and the terrain which is good for farming and building settlements such as cities, residential areas, and transportation networks.
Flood plains are also in this category and they are formed as a result of continuous accumulation of sand, silt, and mud when rivers overflow its banks. Deserts are the hot and dry areas of the world. They are the arid and semi-arid lands with little or no vegetation. These deserts are located in different areas of the world.
Deserts experience very high temperatures, less cloud cover, low humidity, low atmospheric pressure, and very little rain, which makes them have very little vegetation cover. The soil cover is also rocky and shallow and with very little organic matter and as such, it only supports a few plants adapted to the conditions. Plants such as cacti and short shrubs are the ones adapted to the desert conditions because they can conserve water and tolerate the high temperatures.
Animals in the deserts include insects, small carnivores, snakes, lizards, and birds adapted to survive with very little water.
