Biology Biomes Boreal Forests — Taiga Boreal Forests — Taiga The mysterious forests and treacherous quagmires of the far northern latitudes have inspired storytellers for centuries.
World Climate Zones Have you ever wondered why one area of the world is a desert, another a grassland, and another a rainforest? Why are there different forests and deserts, and why are there different types of life in each area?
The answer is climate. Climate is the characteristic condition of the atmosphere near the earth's surface at a certain place on earth. It is the long-term weather of that area at least 30 years.
This includes the region's general pattern of weather conditions, seasons and weather extremes like hurricanes, droughts, or rainy periods. Two of the most important factors determining an area's climate are air temperature and precipitation.
World biomes are controlled by climate. The climate of a region will determine what plants will grow there, and what animals will inhabit it.
All three components, climate, plants and animals are interwoven to create the fabric of a biome. Radiation that reaches the atmosphere here is at its most intense.
In all other cases, the rays arrive at an angle to the surface and are less intense. The closer a place is to the poles, the smaller the angle and therefore the less intense the radiation.
Our climate system is based on the location of these hot and cold air-mass regions and the atmospheric circulation created by trade winds and westerlies.
Trade winds north of the equator blow from the northeast. South of the equator, they blow from the southeast. The trade winds of the two hemispheres meet near the equator, causing the air to rise. As the rising air cools, clouds and rain develop. The resulting bands of cloudy and rainy weather near the equator create tropical conditions.
Westerlies blow from the southwest on the Northern Hemisphere and from the northwest in the Southern Hemisphere. Westerlies steer storms from west to east across middle latitudes.
Air slowly descends to replace the air that blows away. Any moisture the air contains evaporates in the intense heat.Selection Methodology. The Global Ecoregions are the results of regional analyses of biodiversity across the continents and oceans of the world, completed in collaboration with hundreds of regional experts worldwide and by conducting extensive literature reviews.
Discover Earth’s mightiest river and the rainforest wilderness that surrounds its banks! The Amazon is one of Earth’s two longest rivers. It stretches an incredible 6, kilometres (4, miles) west to east across South America – the approximate distance between New York and Rome.
Facts and information about the highest mountain range on the planet. Temperate Deciduous Forest in Virtual Reality – Degrees The following video is a short we shot for you to see this deciduous forest biome in degrees.
If you are on a mobile device you may have to open the youtube . Deciduous forests or temperate deciduous forests are forests dominated with broad-leaf trees that annually lose their leaves. Click to see the fact file for more information or alternatively, you can download our page Deciduous forests worksheet pack to utilise within the classroom or home environment.
Deciduous trees lose their leaves in autumn. The leaves change colour before they fall. The fallen leaves are good for the soil. In spring, new leaves grow and the forest is green again.
