In this section I will talk about climate change, glaciation, and precipitation, lets begin. climate change is defined as s change in global or regional climate patterns, in short it is a change in the long term pattern. Also their is a big difference between weather and climate because weather means the condition of the atmosphere over a short period of time (daily day to day changes) some examples are rain, sun, snow, and the temperature and climate means the long term trends of atmospheric weather given to a region (the four seasons we have) summer, winter, fall, and spring. Also their are factors affecting climate in acronyms it spells out lowern which stand for latitude, ocean currents, wind and air mass, elevation, relief, near water, all of these factors impact climate in a manner that causes it to change. Latitude means the angular distance of a place north or south of the earth's equator, ocean current means the movement of the water and the currents is generated by the force acting upon the water like the earth's rotation, winds, and temperature. Winds and air mass means the volume of the air defined by it's water vapour content and temperature, also air masses adapt to the region and the characteristics of the region it surfaces over. Elevation is the height above a given level especially near sea levels like mountain ranges have high elevations. Relief is the difference in height or elevation between the earth's surface. Finally near water means the region close to seas oceans or lakes and the impacts the regions climate. so lets talk about precipitation now their are three types of precipitations relief, cyclonic, and convectional. relief precipitation the process to it raining, first the on shore breeze is forced up by the mountain range, then it comes to the windward side which acts like a wall and forces the air to go up, then the air is forced up in the clouds which then it cools and expands causing it to condense and when it is to heavy it falls down as droplets, also the leeward side is backside of the mountains where the air warms as it becomes lower it gets drier and the leeward side of the mountain is called the rain shadow due to it's drier climate. Convectional precipitation is common in summers or in continental climate and the process is the ground heats up causing the air to warm, rise and expand, cool moist air forms surrounding location into a the low pressure system created by the rising air, then as the rises it condenses forming light and fluffy clouds and then the water becomes to heavy for clouds to contain which then falls as water droplets and then as the rain falls it cools the ground around it which allows the wind and rain to stop. Cyclonic precipitation happens when the cold and warm front collide and the cold air send the warm upwards and as the warm air is going upwards it condenses forming a anvil shape which then condenses and falls as either rain or hail, also the rotation of the earth causes the warm air to rotate counter clock wise as it moves to the centre of the system, this then results into violent storms to occur for several days. Now glaciation, glaciers are formed by compacted layers of snow, when a new layer of snow forms the previous layer freezes and turns into ice. Glaciers are as old as 250 million years ago, their are two types of glaciers continental and alpine, continental glaciers are continuous masses of ice that are much larger than the alpines, small continental glaciers are called ice fields and big continental glaciers are called ice sheets, also continental glaciers move by their own body weight. Alpine glaciers are smaller glaciers than continental and they begin to form high up in the mountains they move by the force of gravity and when the move they form a u shape and create u shape valleys.
