events in each era. Did more Earth-shaping events occur early in Earth’s history or later on? Explain why. Based on my geologic time scale‚ there are three events in Precambrian Time‚ two events in Paleozoic Era‚ four events in Mesozoic Era and one event in Cenozoic Era. These events mostly occurred later on in Earth’s history. Mesozoic Era has the most events which are four out of ten events on the list‚ mean that Earth-shaping events happened more recently. Earth-shaping events occur later on

Ever heard of the evil know as mountaintop mining? Mountaintop mining is the act of removing resources from mountains until there is nothing left of it. The mountain becomes hollow and is left standing there. The worst part of all is that during the operation so much pollution is being distributed into our atmosphere‚ that it has become one of the biggest reasons why our earth is dying. Mountaintop mining is horrible because it destroys ecosystems and damages biodiversity over an extreme scale.

There is one thing people of Earth have in common. They are all born‚ raised‚ and live their entire lives on planet Earth. They breathe oxygenated air made from the Earth’s trees‚ eat food grown in the soil‚ and drink pure water from Mother Nature’s springs. Yet‚ most humans do not make the connection that their very survival depends upon a healthy‚ thriving planet. Many treat the earth like the gum on the bottom of their shoes. Where is the respect for our one and only Earth‚ who has lovingly given all

Dynamic Earth Has the Earth been static since the beginning of time? Well‚ Earth hasn’t been moving vigorously but it is changing at a steady rate. New geological features‚ rock formations‚ and locations of plates all rise and demolish some in a lifetime and others over a span of millions of years. Earth is dynamic; it constantly progresses and doesn’t rest. Through the churns and molds‚ the twists and turns‚ Earth is active because of plate tectonics and the rock cycle. The ideas

Open Pit Mining Open-pit mining is a kind of surface mining. Mining companies choose this way to get rocks and minerals out of the ground because it is the easiest and cheapest way to do it. Open-pit mining is only used if the rocks or minerals are close to the surface of the land or if a normal tunnel-type of mine isn’t possible. The top layers of the land are removed. After that‚ layer after layer is taken away until the rock or mineral is visible. This is taken out‚ processed when it

Earth Day Founded in 1970 as a day of education about environmental issues‚ Earth Day is now a globally celebrated holiday that is sometimes extended into Earth Week‚ a full seven days of events focused on green awareness. The brainchild of Senator Gaylord Nelson and inspired by the antiwar protests of the late 1960s‚ Earth Day was originally aimed at creating a mass environmental movement. It began as a "national teach-in on the environment" and was held on April 22 to maximize the number of

The media often suggested that this is a relatively new consensus that there is an environmental crisis. They excused people who have ignored the effect of greenhouse gases on climates over the past 40 years. Some know what is really going on out there‚ but most people do not know or know but deny the obvious

Earth Summit International meetings aiming at drawing up measures for the environmental protection of the world. The first summit took place in Rio de Janeiro‚ Brazil‚ in June 1992. Treaties were made to combat global warming and protect biodiversity (the latter was not signed by the USA). The second Earth Summit was held in New York in June 1997 to review progress. The meeting agreed to work towards a global forest convention with the aim of halting the destruction of tropical and old-growth forests
