1D. 8 Identify the human activities that affect the Earth and its environment.
There are various human being activities that affect the Earths environment they are :
2D. P8 Describe the human activities that have an effect on the Earth and its own environment.
Air pollution from using of Fossil Fuels
The transportation found in daily life produces a lot of smoke and unsafe gasses such as Carbon Monoxide, Carbon dioxide & Sulfur dioxide. It is released in the air from the combustion of fossil fuels; this pollutes the air. Inefficient machines release surplus carbon monoxide ; a poisonous gas harming organisms in that environment. Sulfur dioxide can mix with water in the clouds and form an acidic solution which plays a part in acid rainfall, this acidity damages plants and aquatic ecosystems as some organisms cannot endure in acidic surroundings. Acid rainfall also damages and erodes some man-made constructions such as limestone statues etc. Carbon dioxide emissions also contribute to the global warming of the earth, as it builds up in the atmosphere it gradually traps high temperature which as time passes & raises the heat of the planet; this is fatal to all or any ecosystems and surroundings.
Water Pollution from use of fertilizers and various waste materials
The go up of capitalism and consumerism has resulted in a growth of varied products and food being produced at a faster rate. Modern Agriculture uses many synthetic fertilizers which dominantly provides the essential nutrition for plant expansion such as nitrogen, potassium & phosphorus. They receive to plants to improve their growth & take full advantage of their yield. When applied, the surplus fertilizer or nutrients can drip from the land into nearby drinking water resources as the mineral deposits are very soluble in drinking water; this pollutes this inflatable water and starts the procedure of eutrophication and harms the aquatic ecosystem. Eutrophication starts off when
Fertilizers are fatal to aquatic ecosystems and environments in excess. In addition sewage and waste material can also runoff or finish up in aquatic surroundings and either wipe out the organisms in it or pose a serious threat to its inhabitants.
1D. 9 Identify natural factors which have changed the surface and atmosphere of the planet earth.
The Natural factors which may have altered the earth's surface and atmosphere are :
2D. P9 Describe natural factors that contain changed the top and atmosphere of the Earth.
Earthquakes from the movement of tectonic plates
An earthquake is a sudden violent motion of the upper crust triggered by either the movement of large tectonic plates or heavy volcanic activity. When the tectonic plates all of a sudden move it triggers the entire surface to shake and break aside.
some earthquakes make the bottom tremble so violently so it destroys entire panoramas and surroundings. However, earthquakes can also cause landslides and tsunamis, change geology and spoil natural habitats of several living creatures. For example, when an earthquake happens in the center of the sea, it can create waves that are so large that they eliminate coastlines, towns, and forests hundreds of mls away.
Earthquakes have helped to form the Earth's scenery, but they also continue to alter those landscapes. Earthquakes are dangerous to human being, plant and creature life, so when large earthquakes occur, they have the energy to substantially change the top of Earth.
Volcanic Eruptions from Volcanic activity
Volcanic eruptions involve the incursion of liquid magma into a physical environment, and the effects include major transformations, which range from the forming of new land to the devastation of the viability of a preexisting environment. Just one single exemplory case of the creation of new land originates from the Hawaiian Islands, which made an appearance as magma cooled into land after eruptions.
As lava moves across the floor in the wake of an volcanic eruption, any existing plant life is at risk of immediate damage. When lava mixes along with melting snow or rain water, the stream speeds up, and the environmental effects speed up as well, because the destructive ramifications of the lava largely remain, but the spread is generally wider and occurs more quickly.
An exemplory case of this occurred in Montserrat when Chances Top entered a phase of eruption between 1995 and 2000. In 1995, the mountain began offering off indicators of coming activity through eruptions of ash and dust particles. The most extreme eruptions occurred in 1997, and 11, 000 people were evacuated to the northern end of the island as well as to other islands.
The result of the eruptions involved the covering of the administrative centre in mud and ash, and the destruction greater than twelve settlements which were rendered uninhabitable.
