It is 6000 feet deep and 10 miles wide. It also has rocks, sand, and dirt. Inside of the canyon is a river. This river is called the Colorado River. It is 1 mile deep and 18 miles wide.
The Era is made up of six Geologic periods, the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and the Permian. Much of the plants and animals that exististed and evolved was due to the climate and location of the continents. At the beginning of the Paleozoic period, the continents were far apart, but by the end they were close together and on the way in forming the supercontinent called Pangaea. The land was moving by Plate Tectonics. Four hundred and thirty million years ago there was glaciation; this caused an ice sheet to cover what is now North Africa.
An example of this sheet erosion. Runoff is happening everywhere everyday. Erosion by runoff causes landforms to change everyday little by little. Sometimes it may, while its running downhill, make a waterfall. Waterfalls erode pretty fast.
Wegener's theory also provided an alternate explanation for the formation of mountains (orogenesis). The theory being discussed during his time was the "Contraction theory" which suggested that the planet was once a molten ball and in the process of cooling the surface cracked and folded up on itself. The big problem with this idea was that all mountain ranges should be approximately the same age, and this was known not to be true. Wegener's explanation was that as the continents moved, the leading edge of the continent would encounter resistance and thus compress and fold upwards forming mountains near the leading edges of the drifting continents. The Sierra Nevada Mountains on the Pacific coast of North America and the Andes on the coast of South America were cited.
They are all made from pieces of different rocks. They come from sediments which can be found everywhere. Most sedimentary rocks form on earth’s surface. Formation takes millions of years to repeat. A sedimentary rock is a rock made out of sediments that compacted and cemented together.
Geology The Loma Earthquake 1989 Name Course Date due An earthquake is a physical occurrence where vibrations are caused by underlying rocks that are breaking under a lot of stress. The rocks are situated under the earth’s crust and are mostly caused when two tectonic plates come together, and pressure is created along the fault lines. It is then released towards the earth’s surface resulting in an earthquake. In 1989, the Loma Earthquake occurred in the region of the Santa Cruz Mountains that caused a total number of 63 fatalities, 3,557 injured related cases. It also destroyed a lot of property which is estimated to be about $6 billion.
By September 2008, the recorded number of dead was 69,227, with 374,643 injured, 17,923 missing and at least 5 million homeless. The earthquake occurred under some of the steepest and most rugged mountains in the world, the Longmen Shan also called the Dragon's Gate Mountains. These mountains are on the eastern edge of the Tibetan Plateau and are steeper than the Himalayas. They are formed by the collision between the Indian and Asian tectonic plates that began about 55 million years ago. Two long faults in particular, running the length of the Longmen Shan, had slipped many millimetres during the last few hundred years.
One piece of evidence from an ice age shows us that continental drift actually happened. One of the Earth’s ice ages is called Permo Carboniferous, It’s large glacial sediments had covered many countries. These glacial sediments covered South America, Africa, Madagascar, Arabia, India, Antarctica, and Australia. Permo Carboniferous happened about two hundred and fifty million years ago and was discovered by A.G. Smith in 1997. This is important, because these continents could not all have been frozen while they were apart.
On average glaciers move about a meter each day due to the sliding over the bedrock beneath them and the internal deformation of the ice. Ice sheets are dome-shaped glaciers that cover about 19,300 square miles, and they move in all directions. A glacier can be classified as large or small. Large glaciers are called medial moraines and crevasses, and small glaciers are classified as glacier tables and cryoconite holes. Medial moraines are surface ridges of material near the middle of a glacier, and crevasses are wedge-like cracks in the surface of a glacier or of an ice sheet.
How to predict an volcanic eruption Ground Deformation Ground deformation is the change in shape that happens before during or after a volcanic eruption. This happens because the sides of the volcano change shape because the magma in many ways to measure the change of shape of the volcano, like leveling, triangulation and more recently using continuous Global Positioning System (CGPS). It is also possible to use lakes as large tilt meters. Tilt meters measure the tiny degrees of tilt or slope on land. This is one of the oldest methods of knowing when ground deformation was caused because of rising lava.
