Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years
Igneous rocks form from magmas, and most magmas are associated with plate tectonics. Mafic (basaltic) and ultramafic magmas form along the divergent midoceanic ridges and are major components of new oceanic crust. More felsic magmas, such as andesites and rhyolites, are associated with the edges of continental crust at subduction zones along converging plate boundaries. Whether a magma is intermediate or felsic may depend on the relative amounts of oceanic crust and continental crust in the subduction zone that melt to form the magma. The great abundance of granitic intrusions in continental crust is thought to be related to the partial melting of the lower continental crust.
Intraplate igneous activity occurs in the interior of a single continental plate and is thought to be related to mantle plumes (such as the eruptions at Yellowstone National Park) or flood basalts. Intraplate activity is not associated with moving plate boundaries such as subduction zones.

All clouds form due to the warm, moist air rises then getting to cooler elevations and cooling.
<h3>Processes of cooling</h3>
The warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. Eventually, enough moisture will condense out of the air to form a cloud. The air cools as it rises, and eventually clouds form.
Therefore, moist air rises then get to cooler elevations and cooling.

Movement
<span>People are always on the move, but this theme of geography is not just about people moving from one place to another in cars and airplanes.
</span>Location
Location of a place is defined according to its latitude and longitude
Place
Geographers study this geography theme by looking at the characteristics that distinguish one place from another place on Earth
Human/Environment Interaction
Geographers study the way humans interact positively and negatively with their environments. They also study the lasting affects these interactions may have on a place.
regions
A region is a unit on the earth's surface that has unifying characteristics such as climate or industry. These characteristics may be human, physical, or cultural.
