However, scientists disagree on how many biomes exist. Some count six forest, grassland, freshwater, marine, desert, and tundra , others eight separating two types of forests and adding tropical savannah , and still others are more specific and count as many as 11 biomes. Use these resources to teach middle school students about biomes around the world.
A terrestrial ecosystem is a land-based community of organisms and the interactions of biotic and abiotic components in a given area. Examples of terrestrial ecosystems include the tundra, taigas, temperate deciduous forests, tropical rainforests, grasslands, and deserts.
The type of terrestrial ecosystem found in a particular place is dependent on the temperature range, the average amount of precipitation received, the soil type, and amount of light it receives. Use these resources to spark student curiosity in terrestrial ecosystems and discover how different abiotic and biotic factors determine the plants and animals found in a particular place.

A plain landform is land that is relatively flat and does not change much in elevation within a common area. We want pictures and location of the lanforms around the world and we need your help. Click get started button below.
In Asia, China, India, Nepal, and Bhutan are home to one of the eight wonders of the world and one of the most beautiful mountains in the world, the Himalaya Mountains also called the Himalayas.
Nature have provided us with fascinating landforms and features. The most often adored landforms are volcanoes.
Like the perfect cone structure of Mayon Volcano in the Philippines or Mount Fiji in Japan, people look at their beauty and wonder with great appreciation to nature. They often have scattered trees. Savannas such as the Serengeti plains stretch across much of central Africa.
Not all plains are grasslands. Forested plains have different types of trees, shrubs, and other vegetation. Deserts can also be plains. Parts of the Sahara, a great desert in North Africa, are plains. In the Arctic , where the ground is frozen, plains are called tundra. Despite the cold, many plants survive here, including shrubs and moss. Plain Formation Plains form in many different ways. Some plains form as ice and water erodes, or wears away, the dirt and rock on higher land.
Water and ice carry the bits of dirt, rock, and other material, called sediment , down hillsides to be deposited elsewhere. As layer upon layer of this sediment is laid down, plains form. Volcanic activity can also form plains. Plains are useful because due to their flat topography, they support agriculture and farming, which are essential to support a human population. Also, it is easy in the plains to setup industries and develop means of transport and communication.
Land 2. Broad, flat, or gently rolling areas 3. Some plains form as ice and water erodes, or wears away, the dirt and rock on higher land.
Water and ice carry the bits of dirt, rock, and other material, called sediment, down hillsides to be deposited elsewhere. As layer upon layer of this sediment is laid down, plains form. Volcanic activity can also form plains. Plains are very fertile as they are formed by sediments deposited by rivers.
These fertile land are used for agriculture. Plains are flatlands. Plains can either be the result of no seismic activity between tectonic plates or a leveling of the land by glacial activity. Mountains are elevated lands with sharp variations in altitude. Mountains are usually formed by interactions between tectonic plates or volcanic activity. Importance of Northern Plains: The northern plains is a riverine region, being bountifully endowed with the fertile soil, favourable climate, flat surface rendering possible the construction of roads and railways, and slow moving rivers.
All these factors have made this plain very important. Humans use rivers for irrigation in agriculture, for drinking water, for transportation, to produce electricity through hydroelectric dams, and for leisure activities like swimming and boating. Each of these uses can affect the health of a river and its surrounding ecosystems.
Most of the major cities of the world are situated on the banks of rivers, as they are, or were, used as a source of water, for obtaining food, for transport, as borders, as a defensive measure, as a source of hydropower to drive machinery, for bathing, and as a means of disposing of waste.
