Why are granitic igneous rocks lighter in color than basaltic rocks?
Granitic igneous rocks are lighter in color than basaltic rocks because they contain more quartz and feldspar minerals, which are typically light in color. Basaltic rocks, on the other hand, contain more dark-colored minerals like pyroxene and olivine, giving them a darker color.
True or false continental crust is composed mainly of less dense relatively lightweight basaltic rocks including the minerals quartz and feldspar?
False. Continental crust is mostly composed of less dense granite and granodiorite rocks, which contain minerals such as quartz, feldspar, and mica. Basaltic rocks are more characteristic of oceanic crust.
What type of earth plate is more dense?
Oceanic plates are typically more dense than continental plates. This higher density is due to the composition of oceanic plates, which contain basaltic rocks that are denser than the granitic rocks found in continental plates.
Are there seas on the moon?
No, there are no seas on the moon. The dark areas that were once thought to be seas are actually large basaltic plains called maria, formed by ancient volcanic activity. The moon's surface is dry and lacks liquid water.
How much mass would a mole of nitrogen molecules contain?
One mole of nitrogen molecules contains approximately 28 grams (since the atomic mass of nitrogen is approximately 14 g/mol).
What do mid oceanic ridges contain?
They are made up of uplands of mainly basaltic composition. They could contain zones of minerallization.
What liquid is in shield volcanoes?
Shield volcanoes may contain molten rock called magma, particularly of a basaltic composition.
Why are granitic magmas thicker than basaltic magmas?
Granitic magmas are thicker than basaltic magmas because they have higher silica content, which increases viscosity. The higher silica content leads to stronger bonding between the silica tetrahedra, making it more difficult for the magma to flow. Basaltic magmas, on the other hand, have lower silica content and are less viscous, allowing them to flow more easily.
Rocks that contain dark silicate minerals and plagioclase feldspar have?
Basaltic composition, commonly found in oceanic crust and volcanic islands.
Does ginger contain protein?
Yes, ginger contains a small amount of protein. However, the amount of protein in ginger is considered minimal compared to other protein sources.
Do oats contain protein?
Yes, oats contain approximately 52mg of calcium per 100g of oatmeal.
How much carbohydrate does an apple contain?
An average apple typically contains about 25-30 grams of carbohydrates, with the majority coming from natural sugars like fructose.
What is the type of magma contain a lot of silica and water vapor is?
The three types of magma, named for the rock they form are basaltic, rhyolitic and andesitic. Rhyolitic magma is rich in silica and water vapor.
How much kgs 1 micro ton contain?
A ton has 1000 kilograms. Therefore, a micro-ton (millionth of a ton) has 1000 kilograms / 1,000,000, or 0.001 kilograms. Note: This is not a commonly used name; a microton would just be called a gram.
What type of eruptions do mafic magmas cause?
Basaltic magmas are associated with fissure eruptions creating lava flows spilling out from cracks in the crust. This is because basaltic magmas are more viscous and contain a lower concentration of gases than rhyolitic magma and therefore are unable to build up sufficient pressure to produce explosive eruptions.
What are two kind of crust that a tectonic plate may contain?
Tectonic plates can have either continental crust, which is thicker and less dense, or oceanic crust, which is thinner and more dense. The type of crust influences the movement and behavior of the tectonic plates at plate boundaries.
Does the land being moved contain approximately 60 percent water?
mudflow
