An electromagnetic wave can travel through anything - be it air, a solid material or vacuum. ... Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.
Pollution on land gets in our river and ocean through air and people throwing their trash in the river and oceans
The whole water cycle is evaporation, condensation, precipitation, and then infiltration, and at last it is runoff.
Ocean is between the runoff and the evaporation. The rain runoff to the ocean and then start over the water cycle from evaporation.
The cell nucleus acts like the brain of the cell. It helps control eating, movement, and reproduction. It contains the genetic material and controls the function of the cell.
Relative dating is used to arrange geological events and the rocks are left behind the sequence. Stratigraphy is the method of reading the order.
Explanation:
The Relative dating do not provide actual numerical dates for the rocks. The principle states that in an undisturbed sequence of sediments layers are increased in age from the top to bottom.
The difference between relative and absolute dating is the relative age is age of a rock layer when compared to other layer and Absolute age is the numeric age of layer of rocks or fossils and it is determined by using radiometric dating.
The relative dating techniques are used for climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.
