What else can I help you with?
What mineral is commonly found in granite but not found in basalt?
potassium feldspar i think I had this same question in one of my earth science homeworks and thats what i put so hopefullt its right.
State one observable characteristic other than crystal size that makes granite different from basalt?
Granite is typically light in color due to its high silica content and contains visible grains of minerals like quartz, feldspar, and mica. In contrast, basalt is typically dark in color, fine-grained, and contains minerals like pyroxene and olivine.
Which would be washed away more easily by rain sandstone or granite?
Granite and sandstone are two different types of rocks. Granite is made from cooled lava or in some cases magma. Some rocks are made this way. However, sandstone is a sedimentary rock, which forms from sediment squished together. In sandstone, the sediment is sand. This means that the sediment can easily come of by just rubbing the stone against your hand
Which rock is used to build a house?
they used alot of bluestone for mansions in the 1800's, in Sydney were sandstone is prevalent there are sandstone buildings and the Empire Sate Building is made out of Granite, but if one considers concrete a stone or rock then it is.
Which is harder basalt or granite?
Both basalt and granite are types of rock, and a rock is composed of multiple minerals - except for some rocks composed of essentially one mineral like limestone (calcite) or quartzite (quartz). Minerals are crystalline compounds with known characteristics such as hardness, specific gravity, etc Therefore the hardness of the rock depends on the exact location on the rock you are testing the hardness, as it will vary from mineral to mineral. Some minerals even have differential hardness. Granite is composed of quartz, feldspar, and usually some ferromagnesian minerals such as biotite or hornblende (depending on the definition of a granite). Basalt is composed mostly of plagioclase (a feldspar) and pyroxene. Each of those minerals has a different hardness, and geologists never use the hardness of a "rock" to determine what kind of rock it is. Basalt is usually much finer grained than granite so it would be virtually impossible to determine the hardness of the individual mineral crystals. On Moh's hardness scale, the hardness of these rock-forming minerals are as follows: Quartz 7 Feldspar 6 (depending on the species of feldspar) Biotite 2.5-3 Pyroxene 5-6 (depending on the species of pyroxene) So the hardness of a rock is determined by the minerals, and in a coarse grained rock like a granite, the hardness can vary widely. The hardest mineral in granite (quartz) is harder than the hardest mineral in basalt (feldspar), but that's not enough to say that granite is conclusively harder than basalt. The resistance to breaking of a rock (which could be confused with the apparent hardness to a non-expert) is greatly affected by fractures, weathering, induration, welding, and many other features which are independent of mineral content.
Which rock is more porous granite sandstone or slate?
Granite particles are interlocked as the minerals formed from the slow cooling of molten material. Sandstone does not have the same interlocking crystal system, and voids between particles are generally larger.

Give one example of each rock category?

Describe one use for the igneous rocks granite basalt and pumice?
Granite is commonly used in building construction and countertops due to its durability and aesthetic appeal. Basalt is often used as a construction material for roads and railway ballast because of its strength and resistance to weathering. Pumice is used in abrasives, polishes, and horticulture as a lightweight, abrasive material.
How could peices of gness granite and basalt all be found in one conglomerate?
it goes through the rock cycle together

What is mount olga made of?
Kata Tjuta, also known as Mount Olga, is a group of 36 domed-rock formations made up of sedimentary rock, including granite and basalt, held together by sandstone. Mount Olga is one of the two major landmarks in the Uluru-Kata Tjuta National Park in central Australia.

Explian about contact between granite and sandstone?
This is a nonconformity. the contact is between an igneous and sedimentary rock formation. Granite should be on the bottom and sandstone on top, If this is not the case then some type of over-turning has taken place. The depositional envornment allowed sand to acculate over the top of the granite and later consolodated into a rock. This is called a contact. Many years ( perhaps millions) passed) before the whole mass became a rock formation. Can you identify other contacts in the area? If so, you may be able to date this contact and correlate it to other areas in your vicinity. See if you can trace it and look on geologic maps to see if it is mapped. If not, you may have found something that no one has yet discovered.

What igneous rock forms from granite?
Granite is already an igneous rock. If the granite simply melts and re-solidifies it will become granite again. If it melts and is erupted from a volcano, it will form rhyolite. If it melts and mixes with magma of a different composition, then it could form any number of igneous rocks.
