The narrow, ten-mile-long Chaco Canyon is found in New Mexico's northwest. It is isolated by today's standards because it is 70 miles from the closest town and only reachable by rutted dirt roads. Years of erosion have formed the canyon itself out of former seabeds.
The strata of rock and the fossils buried therein indicate millions of years of history. The reason why people abandoned Chaco Canyon is unclear, but a protracted drought may have been a factor. Communities in other parts of the region began to expand in size and significance about this period.

Scattered in many different types of locations, including across the world's deep ocean floors
These nodules are found scattered in many different types of locations, including across the world's deep ocean floors.
What are manganese nodules and where might you find them on the ocean floor?Manganese nodules are authigenic formations made up primarily of Fe and Co, Ni, and Cu-enriched manganese oxides. They can be found in all of the world's oceans, but they typically appear where the rate of sediment formation is modest. Mn nodules do really grow slowly—between a few millimeters and tens of millimeters every million years.Where do manganese nodules come from?When metal compounds that are dissolved in the water column (hydrogenous development) or in the water present in the sediments (diagenetic growth) are deposited around a nucleus, manganese nodules develop. The majority of nodules are the result of both hydrogenous and diagenetic development.To learn more about Manganese module visit:

Why are solar eclipses separated by one saros cycle not visible from the same location on earth?
The Saros cycle is 18 years 11 1/3 days. Because of this 1/3 day means that the earth is 8 hours further along in its rotation than it was at the start of that cycle the area previously facing the sun is now facing away.
Why don't total solar eclipses occur in the same places?When the Moon's shadow falls on the Earth, it causes a solar eclipse. They do not occur every month because the Earth's orbit around the sun does not coincide with the Moon's orbit around the Earth.The total solar eclipse of March 20, 2015 is part of the Saros 120 eclipse family. A Saros series is a collection of eclipses that are separated by 6,585.3 days from the next (or previous) eclipse. This equates to 18 years, 10 days, and 8 hours. The Saros period is unique in that any two eclipses separated by one Saros are very similar. The moon is nearly at the same position in relation to its node (the point at which the moon's orbit intersects Earth's orbit) and is also nearly the same distance from Earth. Furthermore, the eclipse occurs at nearly the same time of year.Three of the moon's orbital periods repeat after one Saros period of 18 years 10.3 days, resulting in these coincidences.To learn more about solar eclipses refer to:

Silica tetrahedra can link into long chains that share oxygen ions through the process of Polymerization.
In polymer chemistry, polymerization or polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. There are many forms of coincidence and different systems exist for classifying them.
In chemical compounds, polymerization can occur through a variety of reaction mechanisms varying in degree of complexity due to the functional groups present in the reactants and their inherent steric effect. In simpler polymerizations, alkenes form polymers through relatively simple radical reactions; in contrast, reactions involving substitution at a carbonyl group require more complex synthesis due to the way the reactants polymerize. Alkanes can also be polymerized, but only with the help of strong acids.
Because alkenes can polymerize in fairly simple radical reactions, they form useful compounds such as polyethylene and polyvinyl chloride (PVC), which are produced in large quantities each year due to their usefulness in the production of commercial products, such as pipes, insulation, and packaging.

Of the three primary forms of subaerial volcanoes, stratovolcanoes consist of alternating layers of tephra and solidified lava.
Stratovolcanoes have relatively steep sides and are more cone-shaped than shield volcanoes. They are formed from viscous, sticky lava that does not flow easily. The lava therefore builds up around the vent forming a volcano with steep sides. Stratovolcanoes are more likely to produce explosive eruptions due to gas building up in the viscous magma.

Radioactive decay in earth, especially in earth's crust, creates a tremendous amount of___. (use a single word for your answer.)
Radioactive decay in earth, especially in earth's crust, creates a tremendous amount of heat.
The Earth's core, which lies 2,900 kilometers (1,800 miles) underneath the planet's crust or surface, is where the planet is warmest. The friction and gravitational attraction that was produced when Earth was formed more than 4 billion years ago provide a modest amount of the core's heat.
The continual production of heat on Earth, however, is mostly caused by the decay of radioactive isotopes like potassium-40 and thorium-232.
In the core, radioactive decay is an ongoing process. There, the temperature may reach more than 5,000 °C, or 9,000 °F. Continuous heat radiation from the core warms rocks, water, gas, and other geological components.
