Which of the following is the best comparison of the density of basalt and granite?
Which of the following is the best comparison of the density of basalt and granite? Basalt is more dense than granite Granite is more dense than basalt Granite and basalt have equal densities The density of both is variable everywhere.
What is the density of basalt?
The density of basalt, one of the most common kinds of terrestrial volcanic rocks, can be as high as 3.0 g/cm3. The only types of terrestrial rocks that are more dense than meteorites are ores – oxides and sulfides of metals like iron, zinc, and lead.
What rock has the highest density?
Two of the heaviest or densest rocks are peridotite or gabbro. They each have a density of between 3.0 to 3.4 grams per cubic centimeter. Interestingly, peridotite are the rocks that naturally occurring diamonds are found in.
Which igneous rock has highest density?
Densities of Igneous Rocks
|Rock Type||Density Range (g/cm 3)|
|Granite||2.50 – 2.81|
|Andesite||2.40 – 2.80|
|Basalt||2.70 – 3.30|
|Gabbro||2.70 – 3.50|
What mineral has the highest density?
Iridium, at a calculated density of 22.65 grams per cubic centimeter, is probably the densest element known to man. Although osmium, at 22.61 g/cubic cm, is close enough to make the distinction difficult. Most people think lead is the most dense! But at 11.37 g/cm3, its barely halfway there!
Do igneous rocks have low density?
The mineral compositions of igneous rocks are usually described as being felsic, intermediate, mafic, or ultramafic (as examples, see Figure 4.7 and Figure 4.8). Felsic rocks are made of light-colored, low-density minerals such as quartz and feldspar.
What are the two most common types of igneous rocks?
The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
Which crust has the lowest density?
Which crust is more dense?
Which is the coldest layer in the atmosphere?
What is the upper limit of Earth’s atmosphere?
The ionosphere is a critical link in the chain of Sun-Earth interactions. This region is what makes radio communications possible. This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km (6,200 mi).
What is the percentage of oxygen in the atmosphere?
What is the upper atmosphere called?
Which gas is least in atmosphere?
The primitive reducing atmosphere of earth was rich in water vapour, carbon monoxide, carbon dioxide, nitrogen and hydrogen. The primitive reducing atmosphere of earth was rich in water vapour, carbon monoxide, carbon dioxide, nitrogen and hydrogen. An oxygen was absent in the primitive atmosphere.
What are the constant gasses in the atmosphere?
Earth’s atmosphere is made up of a combination of gases. The major components of nitrogen, oxygen, and argon remain constant over time and space, while trace components like CO2 and water vapor vary considerably over both space and time.
What is the most important function of the atmosphere?
The atmosphere protects Earth from harmful solar radiations and regulates heating provided by the Sun. The first function is made possible by ozone existing in the stratosphere, the second function is achieved by a mix of gases existing in the whole atmosphere called “greenhouse gases”.
