called a snow slide or snow slip is a rapid flow of snow down a slope. Volcanic eruptions The volcanic eruption itself that may cause harm following the explosion of the volcano or the fall of rock. Second‚ lava may be produced during the eruption of a volcano. As it leaves the volcano‚ the lava destroys many buildings and plants it encounters. Hailstorms Hailstorms are falls of rain drops that arrive as ice‚ rather than melting before they hit the ground. Tornado Tornado is a violent‚ dangerous

he consequences of natural selection for all the species that do not vary and that are genetically identical is that the environment around them may cause them to go extinct. The environment has many powerful factors that play a role in natural selection. 2. Thomas Robert inspired Darwin and Wallace to write the theory for natural selection. He was an English clergyman and economist. The essay was about the increase and decrease of resources and population. It said the while the mankind population

example of an intrusive igneous rock would be granite. Extrusive‚ or volcanic‚ igneous rocks are formed when magma exits and cools outside of the Earth’s surface. These types of rocks are formed when lava flows from volcanoes. They solidify above the surface and have much shorter cooling times. Because lava cools and crystallizes quickly‚ it is a fine grain. The grains in extrusive rocks are quite small‚ so to classify them they have to be placed under a microscope to examine the thin sections to determine

The most intense eruptions occurred in 1997. Although in 1996 on the 17th September‚ many houses were destroyed and many caught on fire‚ and most importantly a major part of the lava dome collapsed.

The woman‚ Yu‚ had been found on a lava embankment; Dan had reported that he found her there‚ presumably after hanging laundry. She had many injuries; a later autopsy determined she died of two massive wounds caused by a tire iron. She also had scrapes from the lava rocks. In 2012‚ a new case prosecutor reviewed the case-there was additional blood evidence found‚ evidently linking DeJarnette to his

changes led to the formation of our world and‚ eventually‚ the creation of life. As stated in the movie 4500 million years ago the earth looks like hell than home. Also‚ we can definitely see it as a “boiling ball of liquid rock or an endless ocean of lava” because the sun was only 22‚000 kilometers away from our planet. As time goes by‚ Meteorite starts showering the planet and brings water 3‚ 900 million years ago. Then‚ 3‚800 million years ago the molten rocks burst in the earth’s crust and rises

Billions of years ago planet Earth did not look like it does today‚ it was covered in lava and volcanoes. There was no possible way that life could exist on the planet. However‚ eventually the planet started cooling down; huge amounts of steam rose causing clouds. Then the clouds rained. One thousand years of continuous raining caused oceans which made earth like it is today. Planet Earth‚ also known as the blue planet‚ has oceans covering three quarters of the Earth’s surface. Oceans have a

they do emerge in islands such as Iceland‚ forming volcanoes such as Heimaey and Surtsey. Volcanoes at constructive margins tend to erupt relatively gently as gases can easily escape from the basalt lava which is at extremely high temperatures and very free-flowing. The main hazards are therefrom from lava flows such as that at Heimaey in 1972. Destructive boundaries occur where two plates are moving towards each other. Where two crusts are moving towards each other‚ the denser crust(eg. the oceanic

The causes of tectonic plate movement and how different processes have shaped New Zealand’s landforms occur nearly every single day. In fact one of these processes is happening right now‚ somewhere on the Earth. The 3 major processes are folding‚ faulting and volcanism. While these take place‚ another “force” is also acting‚ changing the shape of our continents‚ and Earth itself‚ the tectonic plate movement. Earth’s outer shell‚ long thought to be a continuous‚ unbroken‚ crust is actually a fluid

These kinds of volcanoes are characterized by a steep profile and periodic‚ explosive eruptions. 8.
