For example, phenomena and forces observable today; the classical concept that 'the present is the key to the past.]]> 2018-01-23 18:27:00 UTC https://padlet.com/3039561/uiuqlyn22abn/wish/223934690 3039561 https://padlet.com/3039561/uiuqlyn22abn/wish/223940641 the superposition principle, also known as superposition property, states that, for all linear systems, the net response caused by two or more stimuli is the sum of the responses that would have been caused by each stimulus individually. For example, his principle has many applications in physics and engineering because many physical systems can be modeled as linear systems.]]> 2018-01-23 18:36:30 UTC https://padlet.com/3039561/uiuqlyn22abn/wish/223940641 3039561 https://padlet.com/3039561/uiuqlyn22abn/wish/223945416 states that layers of sediment are originally deposited horizontally under the action of gravity.

For example, they are laterally continuous, as a result, rocks that are otherwise similar, but are now separated by a valley or other erosional feature, can be assumed to be originally continuous.]]> 2018-01-23 18:46:32 UTC https://padlet.com/3039561/uiuqlyn22abn/wish/223946614 3039561 https://padlet.com/3039561/uiuqlyn22abn/wish/223947628  geology that states that the geologic feature which cutsanother is the younger of the two features. For example, It is a relative dating technique in geology.

For example,  in sedimentary rocks, it is common for gravel from an older formation to be ripped up and included in a newer layer.

Most fossils do not contain actual body parts but are impressions, molds or casts of the original organism.

For example,  many fossil trackways were made by dinosaurs, early tetrapods, and other quadrupeds and bipeds on land. Marine organisms also made many ancient trackways (such as the trails of trilobites and eurypterids like Hibbertopterus).

For example, Coprolites are classified as trace fossils as opposed to body fossils, as they give evidence for the animal's behaviour (in this case, diet) rather than morphology. ]]> 2018-01-23 18:56:28 UTC https://padlet.com/3039561/uiuqlyn22abn/wish/223953014 3039561 https://padlet.com/3039561/uiuqlyn22abn/wish/223954180 A true form fossil is a fossil of the whole/entire body of the organism, like an actual animal or animal part.
