How often do meteorites hit Earth

Small meteorites hit Earth everyday, but large meteorites hit once a year.

The adjustments of materials that follow a major earthquake often generate smaller earthquakes called

aftershocks

Most earthquakes are produced by the rapid release of which kind of energy stored in rock subjected to great forces

Thermal energy

What does an earthquake's magnitude measure

Size of seismic waves it produces

What is sediment deposited by wind in layers

Could be loess, eolian dunes, or stratified windblown dunes, or sand dunes. The sediments could include sand, clay, silt, or loess.

How does elastic rebound cause earthquakes

Because elastic Rebound cause earthquakes(During elastic rebound, energy is released, some of this energy travels as seismic waves, and then the waves causes an earthquake).

If the mass of one of the objects diubles what is the new force they excert on each other

If you refer to gravitational force, it would also double.

If you refer to gravitational force, it would also double.

If you refer to gravitational force, it would also double.

If you refer to gravitational force, it would also double.

How long before an earthquake do foreshocks occur

It could be days or YEARS before the major earthquake. Plate tectonics are always moving.

What layers of the earth make up the plates

the crust + lithosphere

earth's crust:

crust crust continental crust

lithosphere crust continental and oceanic crust mantle

asthenosphere mantle

lower mantle mantle

outer core outer core

inner core inner core

What are Seismic waves and when do they form

seismic wave are earthquake waves the types are l - waves, p - waves and s- waves they are recorded by seismograph or also called seismograph they form by explosion's, earthquakes and movement (waves) underground.

How did scientists learn about earths interior

rocks and seismic waves

Is decaying plants dissolving minerals in rocks mechanical or chemical

Chemical Weathering

What is the minimum number of seismic stations needed to determine the location of an earthquake's epicenter

The minimum number of seismic stations needed to determine the location of an earthquake's epicenter is THREE.

How did deflation affect the dust bowl in the 1930s

Lowering the land.

What are long sand ridges oriented nearly parallel to the prevailing wind called

longitudinal dunes

During the recent ice age glaciers covered almost what percent of earths land

During the recent ice age, glaciers covered almost 30 percent of earths land.

Does a you shaped valley indicate glacial erosion

A 'U' shaped valley indicates glacial erosion.

In the western states a dry creek is called an arroyo or

a wash

Streamlined asymmetrical hills composed of till is called a

drumlin

The release of stored energy from rocks that are deformed by stress is called elastic

shock
