Princible of horizontality
States that sedimentary rocks left undisturbed will remain in horizontal layers
Law Of Crosscutting Relationships
The principle that a fault or body of rock is younder than any other body of rock that it cuts through
A break in the geologic record created when rock layers are eroded or when rock sediment is not deposited for a long period of time

What is the Coriolis Effect?
The rotation of the Earth causes an interesting phenomena on free moving objects on the Earth. Objects in the Northern Hemisphere are deflected to the right, while objects in the Southern Hemisphere are deflected to the left.
Two important compounds in the atmosphere are?
nitrogen (78%), and oxygen (21%).
Energy from the sun travels to earth as
What are some properties of visible light?
electromagnetic radiation that is visible to the human eye; wavelength in a range from about 380 or 400;
What is thermal Energy
internal energy of a system which is the total present kinetic energy resulting from the random movements of atoms and molecules.
What is usually the warmest part of the day?
High speed winds that reach into the lower stratosphere are called?

Who was the first scientist to explain gravity?
first scientist to discover gravity Isaac Newton
What can parallax be used to calculate?
parallax can be used to determine distances
Which sphere does "transpiration" belong to?
How marerials move toward the Earths surface in a process called
From where does most evaporation come?
Most water vapor in the atmosphere comes from evaporation from lakes, oceans, and rivers (larger bodies of water).
What must be present for clouds to form
Wator Vapor; condensation nuclei
3K is f what significate? Absolute Zero=_________
Absolute zero at 0 K is −273.15 °C (−459.67 °F)
How do most clouds form?
Clouds form when rising air, through expansion, cools to the point where some of the water vapor molecules "clump together" faster than they are torn apart by their thermal energy.
Changes in _________ supported A.Wegener's hypothesis
The hypothesis that continents 'drift' was first put forward by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912. However, it was not until the development of the theory of plate tectonics in the 1960s, that a sufficient geological explanation of that movement was found.
Where is the continental crust thickest?
The continental crust is thicker than the oceanic crust. Specifically the Himalayas in China/Tibet is the thickest part and has the highest mountains
Where is the ocean floor oldest?
At lithospheric subduction zones, where oceanic crust is being drawn into the mantle. These would normally be the point furthest away from its point of origin at the mid-ocean ridge
Where is the ocean floor newest?
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics
In nature where would sublimenation occur?
