Chapter 2 Figure 21 Controlled field experiment to measure the effects of deforestation on the loss of water and soil nutrients from a forest Vnotched dams were built into the impenetrable bedrock at the bottoms of several forested valleys left so that all water and nutrients flowing from each valley could be collected and measured for volume and mineral content These measurements were recorded for the forested valley left which acted as the control site Then all the trees in another valley the experimental site were cut right and the flows of water and soil nutrients from this experimental valley were measured for 3 years. This . powerpoint. will show you the basics of dark matter and dark energy . Their place in the universe . By Jordan . Ilori. . DARK MATTER. Dark matter is a type of matter hypothesized in astronomy and cosmology to account for a large part of the mass that appears to be missing from the universe. Dark matter cannot be seen directly with telescopes; evidently it neither emits nor absorbs light or other electromagnetic radiation at any significant level. Instead, the existence and properties of dark matter are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. According to the Planck mission team, and based on the standard model of cosmology, the total mass–energy of the known universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. Thus, dark matter is estimated to constitute 84.5% of the total matter in the universe and 26.8% of the total content of the universe.. “The most incomprehensible thing about the world is that it is comprehensible.”. – .

Everything in nature is cycled throughout the entire planet. Since matter and energy cannot be created or destroyed, it is changed, or transformed into many different things.. Chapter 2. Figure 2.1. Controlled field experiment to measure the effects of deforestation on the loss of water and soil nutrients from a forest. V–notched dams were built into the impenetrable bedrock at the bottoms of several forested valleys (left) so that all water and nutrients flowing from each valley could be collected and measured for volume and mineral content. These measurements were recorded for the forested valley (left), which acted as the control site. Then all the trees in another valley (the experimental site) were cut (right) and the flows of water and soil nutrients from this experimental valley were measured for 3 years.. 2007.

Extensive Properties: depend on amount of matter in a sample. Mass: amount of matter. Volume: space occupied. Intensive Properties: depend on type of matter, not amount. Density: mass/volume.
