HK Science 4 quiz

QuestionAnswer
What three Characteritics do geologist use to identify rocks? Geologists use color texture, and minerals composition geologist can classify a rock.
What are the grains of a rock? Grains give the rock its texture. T a geologist, a rock's texture is the look ad feel of the rock's surface.
In your own words compare the grain size, shape, and pattern of the conglomerate and breccia in figure. Mostly grain size is big to its easy to see it, The shape is very wide, and the pattern is mostly on a pattern.
what are the three main group of Rocks. The three main groups are Igneous Rocks, Sedimentary Rock, and Metamorphic Rocks.
How do igneous rocks form? Igneous Rocks form from cooling of magma of lava.
Gsniss is kind of Rock that form when heat and pressure inside Earth change granite. To what group o Rocks does geniss belong? Geniss belongs to Metamorphic Rocks group.
How are igneous rocks classified? Igneous rocs are classified according to their origin, texture, and mineral composition.
What are extrusive rocks and intrusive rocks? Extrusive rocks- is igneous rock formed from lava that erupted onto Earths surface. Intrusive rocks, is Igneous rocks that formed when magma harden beneath earth's surface.
Which is extrusive? Which is intrusive? Grainte is intrusive because it has crystals and Basalt is extrusive because it forms mid-ocean or lava.
What are two common uses of igneous rocks? Tools and building is the two common uses of igneous rocks.
How do igneous rock form? Igneous rock forms from the cooling magma or lava.
Would pumice be a good material to use to make a floor? Explain. No, because its two course and its easy to break it.
What is Silica? Silica-is material formed from Oxygen and silicon.
What is sediment? Sediment- is small, solid pieces of material that come from rocks or living things.
Place these steps in the formations of sedimentary rock in the paper sequence: compactions, erosion, cementation, deposition. Erosion- running water, wind or ice loose and carry away fragments of rocks. Deposition- is the process by which sediment settles out of the water or wind carrying it. Compaction- is together sediments press that process. Cementation- is the process i
In layers of sedimentary rock, where would you expect to find the oldest sediment? Explain answers. Compaction, beacause the layers push down on the layers beneath them and form sedimentary rocks.
What are the three main types of sedimentary rock? The three main rocks are clastic Rock, Organic rock, and Chemical rock.
Explain how this sedimentary rock forms. Coal forms from pressure and plant.
What does metamorphic mean? Metamorphic means a type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions.
What and under what condition are metamorphic rocks formed heat and pressure deep beneath earth's surface can change any rock metamorphic rock
What characteristic of a metamorphic rock do geologists use to classify them geologists classify metamorphic rocks according to the arrangement of the grains that make up the rocks.
how does a foliated metamorphic rock formed heat and pressure deep beneath earth's surface can change any rock into metamorphic rock
Which of the rock is figure 17 is foliated. How can you tell. Genesis and slate are foliated because they are thin, flat and breakable.
Which is the main use of metamorphic rocks? Certain metamorphic rocks are important materials for buildings and sculptures
Which might be more useful for carving chess pieces marble or slate? Marble might be more useful because marble has a fine, even grain, easy to cut and easy to polish, like the Abraham Lincoln memorial in Washington DC
