Geophysics

volcanos, mountains

Seismic waves affect us because they are what causes the motion from an earthquake that destroy buildings and such. The three types of seismic waves are surface waves primary waves also called P-waves and secondary waves also called S-waves.

uhhh i think its weathering??

The Ring of Fire is a belt of volcanic and seismic activity that borders most of the Pacific Rim. It is characterized by a high concentration of earthquakes and active volcanoes due to the movement of tectonic plates in the region.

Geography is the study of the earth and its people. Maps and globes are some of the tools used to study the physical and human characteristics of our planet. LANDSAT photos and Geographic Information Systems (GIS) help geographers provide information used by government and business leaders as they plan and make decisions.

Our planet, Earth, is part of a solar system made up of a sun, nine planets, and thousands of smaller bodies. Life on Earth could not exist without the heat and light provided by the sun or the atmosphere of gases that surrounds the planet. The earth's rotation creates a twenty-four hour day and night, while its orbit around the sun and 23½ degree tilt produce the seasons.

Inside the earth are layers of varying thickness and composition: the inner core, outer core, mantle, and crust. Scientists theorize that volcanoes, earthquakes, and continental drift are caused by the movement of tectonic plates that float on top of the liquid rock in the mantle. The forces of weathering and erosion also continually change the earth's surface.

People have adapted in order to live on various landforms. Mountains, plateaus, valleys, and other landforms are found on land and under the oceans. About 70 percent of the earth's surface is water.

Yes it very much depends upon what type of soils are in the region. In some very dry locations the ground wire is strung along with the rest of the pole wires from pole to pole. In very gravelly soil conditions there is no grounding medium no matter how deep the ground rods are placed. Other places that give trouble is solid rock installations.

Mass wasting is the downslope movement of soil and weathered rock debris. Streams can deepen valleys by downcutting (erosion), but widening or enlarging of the valley via erosion of the sides or slopes is accomplished largely through mass wasting. Mass wasting delivers the weathered rock material and soil to the streams, which carry it away to some site of deposition.

Yes, friction boundaries cause friction whenever they move. Whenever there's movement, there's friction or rubbing of one plate against the other or of a plate against the earth's mantle.

I don't know but it is convection

That's correct.

They lodge together pressure builds up and overcomes the friction

the plates jolt past each other and make earthquakes

this also creates ridges in the land eg san andreas fault

lithospheric plate movement

Information gathered by geographically spaced seismometers positioned to enable a three dimensional extrapolation of the position of the earthquake epicentre and the nature of the movement which caused it.

A place where an earthquake has occurred in the past but not recently is known as a seismic gap.

Sedimentory rocks form in several stages, which are: weathering, errosion, sedimentation, cementation and at the end lithification.

In case of formation of metamorphic rocks, rock of any origin altered in mineralogical composition, chemical composition, or structure by heat, pressure, and movement. Nearly all such rocks are crystalline.

I need help

it works like air and a radiator the heated air rises and cools then falls and the process is repeated again and again

Earthquake shock absorbers do exactly what they say on the tin, they absorb some of the energy generated by an earthquake, in order to prevent structural damage. Most tall building in San Francisco are built on the shock absorbers, so that they can still stand after an earthquake

Acid rain causes more mass wasting when people pollute the enviroment and when they smoke make too much use of ciggarete

The Himalayas were formed when the Indian Plate collided with the harder European Plate. The Indian Plate was thrust under at what is termed a subduction zone.

No, the time it takes for magma to complete one circular convection flow can vary depending on factors such as the temperature gradient, viscosity of the magma, and size of the magma chamber. In general, the process of convection in magma chambers can occur on timescales ranging from hundreds to thousands of years.
