Cause and Effect of Volcanoes Any natural opening in the Earth’s crust‚ called a fissure‚ where melted rock‚ ash‚ gases‚ and steam come out is called a volcano. Volcanoes look like mountains‚ but they are really flat land that is pushed upward because of the pressure below the earth. The pressure comes from hot magma and gases that build up below the earth’s surface and that work up to the surface through cracks in the earth’s plates. As it is forced up to the surface‚ the gases and magma push

Electricity from Natural Gas Natural gas is a fossil fuel formed when layers of buried plants and animals are exposed to intense heat and pressure over thousands of years. The energy that the plants and animals originally obtained from the sun is stored in the form of carbon in natural gas. Natural gas is combusted to generate electricity‚ enabling this stored energy to be transformed into usable power. Natural gas is a nonrenewable resource because it cannot be replenished on a human time frame.

time. Natural selection is where animals with advantageous characteristics produce more offspring‚ therefore passing down favoured genes. In the more developed parts of the world‚ medical care and access to food means natural selection is lesser‚ as selective forces that were there before e.g some diseases and predators‚ are no longer there. Therefore‚ some humans that have characteristics that would have previously meant they produce less offspring‚ reproduce at a similar rate to humans with more
