Science Flashcards
In which part or the earth are rocks formed?
Rocks are formed in the mantle
How are all igneous rocks formed?
Igneous rocks are formed by the cooling of molten magma on the earths surface.
Explain the difference between the ways in
which extrusive igneous rocks and intrusive rocks are formed.
Extrusive igneous rock cools very fast on the surface and is created by lava.
Intrusive igneous rock cools very slowly beneath the surface and is created by magma.
List three example of extrusive igneous rocks.
Basalt, andesite, obsidian.
What clues does the size of the crystals in an igneous rock provide about how the rock was formed?
Certain igneous rocks can also be identified by the size of their crystals. Granite and rhyolite are both igneous rocks made of the same minerals. Granite has large crystals and rhyolite has small crystals.
What are sediments?
Any particular matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of a body of water or other liquid.
How are sedimentary rocks formed?
Sedimentary rocks start off at gravel, sand and clay then is transported to wind, flowing water and glaciers.
Suggest a way of checking that a rock sample that appears to have seashells embedded in it is limestone.
Sedimentary rocks contains any type of fossil-trace or true fossil. The colour rock and textures as well as the substance that the rock contains should be checked since those characteristics is what allows us to categorise the rock.
Explain why some layers of sedimentary rocks are tilted or bent.
Not all rocks go through the same progress.
Twenty elements of the periodic table.
Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulfur, Chlorine, Argon, Potassium, Calcium
What is a parent rock?
An original rock which something else was formed.
Cells
Cell membrane, cell wall, vacuole, nucleus, chloroplast.
Cell animals
Nucleus, cell membrane, cytoplasm.
Inside of plants.
Anther, petal, stigma, style, sepal, ovary, filament, receptacle.
Metals
Elements that conduct heat and electricity, shiny solids that can be made into thin wires and sheets that bend easily. Mercury is the only liquid metal.
