How does an igneous rock turn into a metamorphic rock? What evidence do we have for the movement of tectonic plates? Explain how we know that tectonic plates move. How does "global positioning system" (GPS) technology work? What can we learn about plate tectonics by using GPS technology?
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside

The crust is the uppermost of the earth's three layers. The other layers are the mantle and the core. It is the coolest of all the layers of the earth. It is solid because of the low temperatures and pressures which are present in it. ...
Moisture Moisture = Water Vapor (gas) Gets into the atmosphere by: 1.Evaporation = liquid to gas (opposite of condensation) 2.Transpiration = plants release. Do Now 1/14/13 In order for a metamorphic rock to become an igneous rock, what must happen? In which layer of the Earth do conv...
U-Pb dating is often used to date igneous (volcanic) rocks, which can be hard to do because of the lack of fossils; metamorphic rocks; and very old rocks. All of these are hard to date with the other methods described here. Rubidium-strontium (Rb-Sr) dating:Radioactiverubidium-87 decay...
