If the lithoseshpere moved less how would the surface of the earth be affected

Quasar spectra often show many absorption lines that all appear to be as a result of the same electron transition (such as level 1 to level 2 in hydrogen) but that fall at different wavelengths in the spectrum. Why do we think this is the case?

Which example provides scientific data about the earth's interior? a. the motion of continents b. earth's orbit around the sun c. how seismic waves travel d. the size of volcanoes on the earth's surface

During an investigation, a student determines that a copper sample has a density of 8.10 g/ml. What is the students percent error of the accepted density for copper is 8.96 g/ml

A roller coaster car has a mass of 290. kilograms. Starting from rest, the car acquires 3.13 * 10^5 joules of kinetic energy as it descends to the bottom of a hill in 5.3 seconds. Calculate the height of the hill. [Neglect friction.

Describe the relationship between temperature, density, and movement of air in a convection cell

Describe how the competition between invasive and native species might affect a food web

Which vector should be negative? any vector whose magnitude is less than 1 a displacement in the direction North any vector whose magnitude is greater than 1 the velocity of a falling object

Acceleration is a scalar quantity true or false

Find a numerical value for rhoearth, the average density of the earth in kilograms per cubic meter. Use 6378km for the radius of the earth, G=6.67*10-11m3 / (kg⋅s2), and a value of g at the surface of 9.80m/s2.
