Geography

          Spring brings warmer weather. Flowers come into bloom, trees regain their leaves and blossom. Some sunshine will be accompanied by cool breezes and light showers of rain.

          In summer, the days are long and the land receives a lot of sunshine. Temperatures are high and trees and plants are green and leafy. Thunderstorms will bring rain.

          Temperatures drop during autumn, as the days begin to get shorter. Some places may experience violent storms at this time of year. Leaves go brown and fall from the trees.

          In winter, the days are short and the skies may be filled with dark, grey cloud. Many trees are bare, and the ground is often covered with frost, snow or ice.

          In geography, the temperate or tepid climates of Earth occur in the middle latitudes, which span between the tropics and the polar regions of Earth. In most climate classifications, temperate climates refer to the climate zone between 35 and 50 north and south latitudes (between the subarctic and subtropical climates).

          These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small. They typically feature four distinct seasons, Summer the warmest, Autumn the transitioning season to Winter, the colder season, and Spring the transitioning season from winter back into summer. In the northern hemisphere, the year starts with winter, transitions in the first half year through spring into summer, which is in mid-year, then at the second half year through autumn into winter at year-end. In the southern hemisphere, the seasons are swapped, with summer between years and winter in mid-year.

          The temperate zones (latitudes from 23.5° to the polar circles at about 66.5°, north and south) are where the widest seasonal changes occur, with most climates found in it having some influence from both the tropics and the poles. The subtropics (latitudes from about 23.5° to 35°, north and south) have temperate climates that have the least seasonal change and the warmest in winter, while at the other end, Boreal climates located from 55 to 65 north latitude have the most seasonal changes and long and severe winters.

          In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentally (how large a landmass is), and altitude also shape temperate climates.

The more we use mountains, the more we threaten the lives of the people, animals and plants that live there. We must continue to take care of our mountains so that they can be enjoyed by future generations.

 Sometimes waste is stored inside a mountain.

Some people think that mountains are a useful place to store rubbish because they are remote and scarcely populated. Tunnels can be made in a mountain to keep the rubbish out of sight. But poisons from this rubbish can seep into the ground, killing plants and animals that live nearby.

 The way of life in the mountains is under threat.

If levels of pollution increase and the Earth’s temperatures continue to rise, life will get more difficult for mountain people. Food and fuel could become scarce as mountain habitats change. Melting glaciers are also likely to cause floods, soil erosion, falling rocks and landslides.

Mountains may change in your lifetime.

Over millions of years, mountains grow and mountains wear away. Sometimes, a natural disaster can change the landscape dramatically. In 2004, a tsunami was caused by an earthquake under the sea in Asia. Whole islands disappeared from view and many people drowned. We cannot predict how mountains will change. However, we can do our best to protect them.
