The term âcarrier oilâ encompasses hundreds of different oils and butters. In the most basic sense, the word âcarrierâ serves to distinguish oils that are not âessentialâ oils. Common carrier oils include olive oil, coconut oil, shea butter, cocoa butter, grapeseed oil, canola oil, sweet almond oil, walnut oil, and more. The oils in this category vary wildly in terms of texture, colour, thickness, nutritional composition, and scent, but generally they are our base oils/butters.
In order to proceed with his research, Ebbinghaus had first to invent stimulus materials. These needed to be relatively simple, neutral as to meaning, and homogeneous. They needed to be available in large numbers and to allow quantitative manipulation of the amount of material to be retained.
Wegener also used fossils to support his argument for continental drift. A fossil is any trace of an ancient organism that has been preserved in rock. For example, Glossopteris (glaw sahp tuh ris) , was a fernlike plant that lived 250 million years ago.egener gathered evidence from different scientific fields to support his ideas about continental drift. He studied land features, fossils, and evidence of climate change. In 1915, Wegener published his evidence for continental drift in a book called The Origin of Continents and Oceans.
