Historical eruptions[ edit ] Eruptions of Etna follow a variety of patterns. Most occur at the summit, where there are currently as of [update] five distinct craters — the Northeast Crater, the Voragine, the Bocca Nuova, and the Southeast Crater Complex 2. Other eruptions occur on the flanks, which have more than vents ranging in size from small holes in the ground to large craters hundreds of metres across. Summit eruptions can be highly explosive and spectacular, but rarely threaten the inhabited areas around the volcano. In contrast, flank eruptions can occur down to a few hundred metres altitude , close to or even well within the inhabited areas. Numerous villages and small towns lie around or on cones of past flank eruptions. Since , Etna has had four flank eruptions — in , — , — , and —

Although they also posed new questions, the thousands of satellite photographs brought back from the Moon have permitted us to map its surface with greater accuracy than Earth could be mapped a few decades ago. We now have over kg of rocks from nine places on the Moon, rocks that have been analyzed by hundreds of scientists from many different countries. Data from a variety of experiments have revealed much about the Moon’s deep interior.
As it turns out, the Moon is truly a whole new world, with rocks and surface features that provide a record of events that occurred during the first billion years of the solar system. This record is not preserved on Earth because all rocks formed during the first million years of Earth’s history were recycled back into the interior. The importance of the Moon in studying the principles of geology is that it provides an insight into the basic mechanics of planetary evolution and events that occurred early in the solar system.
Mount Etna, or Etna (Italian: Etna or Mongibello [mondʒiˈbɛllo]; Sicilian: Mungibeddu [mʊndʒɪbˈbɛɖɖʊ] or â Muntagna; Latin: Aetna), is an active stratovolcano on the east coast of Sicily, Italy, in the Metropolitan City of Catania, between the cities of Messina and lies above the convergent plate margin between the African Plate and the Eurasian Plate.
The sparsely populated high desert of eastern Oregon is home to three localities producing natural copper-bearing labradorite feldspar. Photo by Robert Weldon. Over five days in late July , we visited three important sources of gem-quality sunstone in eastern Oregon: Oregon sunstone, the official state gemstone since , is natural copper-bearing labradorite feldspar. Feldspars are silicate minerals that contain variable amounts of sodium Na , potassium K , and calcium Ca.
For more on feldspar classification and nomenclature, see box B in Rossman No discussion of this topic would be complete without mention of the controversy surrounding treated copper-bearing feldspar; Rossman provides a chronology.

Lava from the Kilauea volcano in Hawaii that flowed into Kapoho Bay has created nearly a mile of new land. US Geological Survey officials say the flow was still very active and there is no way of.
Place the base on a stable and flat surface. The base ring has x2 screw holes that allow you to fix the base if required onto a suitable flat even surface. We recommend you use suitable screws x2 of the same specification for the desired surface you will be fixing the base onto. You must ensure the base is positioned and secured safely onto to the desired surface. Once fixed, the base should be free from movement at all times. Stalagmite shapes may form during the warm up process, these will then melt and the lava will begin to flow.

Each Hawaiian island is made up of at least one primary dormant volcano, although many islands are composites of more than one. The Big Island of Hawaii, for instance, is constructed of 5 major volcanoes: Mauna Loa is the largest active volcano on Earth.

A blob of hot volcanic lava struck an ocean tour boat just off the Big Island of Hawaii on Monday, injuring nearly two dozen people in the worst casualty incident to date from the ongoing eruption.
The boat was able to return to its port in Hilo less than an hour later, and three of the injured were taken to a local hospital by ambulance, Mr Okinaka said. Nine or 10 others with less severe injuries were driven to the hospital by private vehicle, and 10 more people were treated by paramedics at the port, he told Reuters.

Then plug it in and turn it on. It is normal for the glass to have small air bubbles and moulding scars. Warm up takes between 1 and 3 hours depending on the size of the model and the surrounding temperature. Stalagmite shapes may form during the warm up process, these will then melt and the lava will begin to flow. Operation Your Mathmos lava lamp will operate best after it has been used four or five times. For the first few times you may see small air bubbles in the lava.
Please do not leave your lava lamp on for more than six hours a day; this will prolong the life of your lamp. Overheating will shorten the light of the life of the lamp. Overheating is occurring if there is either one large bubble or many smaller ones. Never move or shake the lamp when it is in use or still warm as this causes irreparable clouding.
From indulgent gourmet weekends to adrenaline-charged outdoor activities, there is something for everyone. Trentham Falls Trentham Falls is one of the longest single drop waterfalls in Victoria, plunging some 32 metres over basalt columns. Trentham Falls was formed some five million years ago from molten lava rapidly cooling as it flowed along the old Coliban River valley. At the base of the Falls, quartz gravel and the former river bed can be seen. The Falls reserve protects one of the best remnants of original vegetation in the area, with stands of manna gum, messmate, stringybark and narrow-leaved peppermint.

References Generic Radiometric Dating The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth. The equation is the one which describes radioactive decay: The variables in the equation are: Pnow – The quantity of the parent isotope that remains now. This is measured directly. Porig – The quantity of the parent isotope that was originally present.
This is computed from the current quantity of parent isotope plus the accumulated quantity of daughter isotope. Standard values are used, based on direct measurements.
