1. What transitions has Earth gone through and why? The young earth was anything but habitable. Radioactive elements decaying within its mass and impacts from debris raining down form space generated intense heat. There was no life during this era. Is called the Hadean era and was formed about 4.5 billion years ago. Hadean comes from the Greek word Hades which means “Hell”. That’s how hot the Earth’s temperature was. The next phase in the Earth’s history was the Archean era. It existed

How does surface reflection affect global temperatures? Lighter surfaces – e.g. snow and ice reflect large amounts of radiation back to space (high albedo) – reduces temperatures. Reduction in

CH 2 -According to Aristotle‚ larger‚ heavier objects were supposed to fall to the ground faster than smaller‚ lighter objects. Galileo performed a number of experiments to Aristotle’s pronouncements‚ that two objects of different weight dropped from the same height fall down at exactly the same rate. -Copernicus published his findings in 1543‚ the same years as his death‚ in a text entitled (On the Revolutions of the Celestial Spheres). -Heliocentric theory was proposed by Aristarchus of Samos

To what extent can preparedness and planning mitigate the effects of Volcanic Hazards (40 marks) More than 500 Million people live within 50 miles of a volcano‚ the potential therefore exists for major loss of life and damage to property and infrastructure‚ particularly when urban areas are situated in close proximity. Mitigation of such losses can be achieved through careful preparedness and planning. Preparedness is the process of ensuring that an organization has complied with the preventive

Sea turtles are threatened and endangered throughout their natural range due to various anthropogenic interferences‚ such as poaching and habitat destruction (World… c2016). Sea turtles provide many ecological benefits‚ such as acting as distributors of nutrients and sculptors of both terrestrial and marine substrate (Mancini et al. 2011). However‚ global climate change is threatening sea turtle populations’ ability to continue to provide these benefits (Mancini et al. 2011). Beach habitat loss due

Greenhouse Effect and Global Warming Today‚ at the down of 21st century‚ together with the 20th century‚ especially the second half‚ is the time when Earth’s environment change at the very rapid rate. Humans have lived on this planet for thousands of years. I think now is the time to think how do we impact the place where we live‚ and the only place where we can live. The impact of human race on the natural processes of our planet has now reached the levels that are now global‚ not local

Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions‚ or in the distribution of weather around the average conditions (i.e.‚ more or fewer extreme weather events). Climate change is caused by factors such as biotic processes‚ variations insolar radiation received by Earth‚ plate tectonics‚ and volcanic eruptions. Certain human activities have also
