| Question | Answer |
|---|---|
| A hotspot created the Dontbefooled Island chain. Using the information on this slide which way did the oceanic plate move during this time period? | Southwest |
| The rocky earth is divided into zones based on density. Identify the zone which we live on plus the upper 100km of the mantle | Lithosphere |
| Name the type of plate tectonic boundary depicted in the circle area labeled D, (what crustal types are involved) | Continental and continental and convergent |
| Identify a modern or ancient example of the plate tectonic boundary depicted by the circle area labeled D | Applachian Mountains, North American Plate |
| What types of partial melting of rocks takes place at the location labeled N? | Decompression |
| The process that circulates heat and material in the solid mantle is called __________. This is the driving force for plate tectonics | Convection |
| Identify the 4 criteria stated in the mineral definition | Solid, naturally occurring, inorganic, specific chemical compound |
| Apply the definition of a mineral we learned in class to the following question: Is a sapphire made in a laboratory considered to be a mineral? | No, because it is man made. It is not organic |
| Identify and explain one of the hypotheses for Earth’s internal heat energy sources (heat source that powers plate tectonics | Heat stored from Earths formation in the core |
| Type of bonding, which is characterized by the sharing of electrons from one atom to another during the formation of a mineral. This type of bonding is strong | Covalent |
| Explain how the elements heavier than iron (ex. Gold) were created in the universe | From particles forming to gather as well as help from other elements and minerals, created by nuclear transfusion |
| Type of plate tectonic boundary where no crust is destroyed, an example is Californias San Andre’s Fault | Transfer Boundary |
| What stress is associated with the type of boundary exhibited by the San Andre’s fault | It is pulling California into the ocean more |
| The _____________ is a research strategy based on observations and experiments | Scientific method |
| Plate I has a density of 3.15 g/cc (grams/cubic centimeter) and Plate II has a density of 3.0 g/cc. If these two oceanic plates collide, explain what will happen to each plate | Plate II would rise up, because it has the lower density. Plate I would be submerged because it has a higher density |
| What is the age of the Earth? | 4.53 Billion Years old |
| Identify two processes or ways new continental crust is created | Volcanoes and Accretion |
