A combination of minerals, usually containing one or more of htese elements: Oxygen, Silicon, Aluminum, Iron, Calcium, Sodium, Potassium, Magnesium
solid, inorganic, naturally occurring substances with a specific chemical formula and general structure.
The process by which rock changes from one type to another
molten material inside the volcano, and deep beneath the Earth's crust
molten material running out of the volcano
Outer most layer of the Earth
Layer of the Earth just beneath the crust
Rock formed by heat and pressure, usually deep beneath the Earth's surface, although hot lava can form "contact metamorphic rock."
Rock formed by weathered and eroded material. Also from fossils or other dead organic material.
Rock formed by molten rock,such as magma or lava. Magma and lava are essentially the same, they are called so by where they are located and not really what they are made of.
Intrusive Igneous Rock
Rock formed by magma cooling inside the volcano or magma chamber.
Extrusive Igneous Rock
Rock formed by lava cooling on the surface of the Earth, outside the volcano.
Clastic Sedimentary Rock
Rock formed by weathered debris.
Chemical Sedimentary Rock
Rock formed by chemicals dissolved in solution
Organic Sedimentary Rock
Rock formed by the accumulation of plant or animal debris
Foliated Metamorphic Rock
Rock formed by heat and extreme pressure resulting in bands or layers
Nonfoliated Metamorphic Rock
Rock formed by heatr and pressure that do not have bands or layers.
What are the 3 types of rocks?
igneous, sedimentary, metamorphic
What type of rock is formed by heat and pressure?
What type of rock is formed by volcanic activity?
What type of rock is formed by weathering and erosion?
What is melted rock called?
When igneous rock is weathered and eroded, what type of rock does it become?
When metamorphic rock becomes weathered and eroded, what type of rock does it become?
When metamorphic rock melts, what does it become?
When sedimentary rock melts, what does it become?
When magma cools, what type of rock does it become?
In order for metamorphic rock to become igneous rock, what must happen?
metamorphic rock must melt, and then cool.
What type of rock do you think is at a subduction zone (convergent boundary)? Why?
metamorphic rock, this slab of oceanic crust is
under extreme heat and pressure as it goes back down into the mantle to be recycled.
What does metamorphic rock turn into at subduction zones (convergent boundaries)?
