As www.marinebio.net states‚ Wailea-Makena‚ Hawaii‚ East Maui County was caused by a hotspot or an extra hot plume of molten rock. This happens when heat rises as a thermal cloud from inside of the Earth. Heat and pressure at the bottom of the tectonic plate forces magma to form which then rises through cracks and erupts to form volcanoes. As volcanoes move away from a hotspot‚ they start to erode and become inactive. Maui is the third oldest volcano of the main Hawaiian islands and could still

Plate Movement Tectonic Plates move in four different ways. When tectonic plates come into contact‚ changes on the earth’s surface occur. 1. Diveregnt Boundary- Plates move apart‚ spreading horizontally. 2. Convergent Boundary-Plates collide causing either on plate to dive under the other or the edges of both plates crumple. 3. Transform Boundary- Plates slide past one another. [pic] Folds and Faults When two plates meet each other‚ they can cause a folding or cracking of the rock. The transformation

6th Grade Science Vocabulary List 1. Qualitative Observation- To study by using the 5 senses- things you see‚ hear‚ feel‚ smell‚ and taste. 2. Quantitative Observation- to study and look for numbers-measurements‚ values‚ and quantities. 3. Dependent Variable- the variable a scientist observes or measures during an experiment. 4. Independent Variable- The factor that is changed by the investigator to observe how it affects the dependent variable.

Being so close to an active volcano poses many risks to communities. Even though Mount St. Helens erupted over 30 years ago we know that it is still an active volcano. Future eruptions can kill and injure entire communities. Since the eruption in May of 1980 of Mount St. Helens‚ geologists have come to a better understanding of both the mechanics of volcanoes and the dangers they present to the environment and communities. Did you know that volcanic ash is actually small glass particles? Or that

changes which take place during metamorphism? High temperatures cause dehydration‚ range of pressures 12. Describe contact metamorphism. Cold rock is intruded by hot magma 13. Describe regional metamorphism. Motions of plates at convergent plate boundaries 14. How is metamorphism like cooking (called an "isochemical" process). As temp and pressure increase‚ atoms become immobile‚ therefore creating new minerals 15. What are

1. The science of biogeography is the description of distribution of life and the explanation of this description. The description is based on both time and space. This describes how things look and why they are there. It also looks to answer the question – are these features the same over time? Biogeography arose with the theory that life on earth is a non-random distribution. This is the most important observation leading to the field of biogeography. The study of biogeography includes many other

Geology Study Guide Chapter 1 Themes of Textbook The Earth is a unique‚ evolving system. Within the Earth System‚ chemical elements pass in cycles between different types of rock and sea‚ rock‚ and air. Plate Tectonics explains many Earth processes. Earth has a core‚ mantle‚ and crust. Measurements: 1 Ka=1 thousand years ago 1 Ma=One million years ago 1 Ga=One billion years ago The Earth is 4.57 billion years old. Big Bang All matter and energy was initially packed into

caused by convergent tectonic plates coming together. By contrast‚ volcanoes are not usually created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth’s crust in the interiors of plates‚ e.g.‚ in the East African Rift‚ the Wells Gray-Clearwater volcanic field and the Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "Plate hypothesis" volcanism.[1] Volcanism away from plate boundaries has also
