What is the planet Mercury made up of?
it is made of heat resistant rock and magma. there is no atmosphere.
Why is igneous rock so resistant to weathering and erosion?
Igneous rocks are resistant to weathering and erosion because they are formed from cooled magma or lava, which solidifies quickly and has a crystalline structure, making it harder for external forces to break down. Additionally, they generally lack internal pores or weaknesses that would make them more susceptible to weathering. Lastly, the mineral composition of igneous rocks often consists of minerals that are chemically stable and less prone to chemical weathering.
What type of magma is primarily associated with high viscosity?
Magma with high silica content is primarily associated with high viscosity. This type of magma tends to be more resistant to flow due to its high concentration of silica, which promotes the formation of more complex and interconnected mineral structures. This results in a slower flow and more explosive eruptions.
What rocks are naturally heat resistant?
Igneous rocks like granite, basalt, and obsidian are naturally heat resistant due to their formation from cooling magma or lava. Additionally, metamorphic rocks like slate and quartzite can also be heat resistant due to their high density and lack of pore space.
Which flows easier high silica magna or low silica magna?
Low silica magma typically flows easier than high silica magma because low silica magma has lower viscosity, meaning it is less resistant to flow. High silica magma is more viscous due to the presence of more silica tetrahedra in its composition, making it thicker and more difficult to flow.

What mineral affects the thickness of magma?
The mineral that significantly affects the thickness (viscosity) of magma is silica. Higher silica content in magma leads to increased viscosity, making it thicker and more resistant to flow. Conversely, magma with lower silica content is less viscous and flows more easily. This variation in viscosity plays a crucial role in determining the type of volcanic eruptions and the shape of volcanic landforms.
Is the following sentence true or false high - silica magma has high viscosity?
True. High-silica magma, such as that found in rhyolitic compositions, has a high viscosity due to the increased bonding between silica molecules. This results in a thicker, more resistant flow compared to low-silica magma, which is more fluid and has lower viscosity.
How do landforms form from magma and become exposed?
The magma slowly cools over time into intrusive igneous rock. Later, often because the land is uplifted, the surrounding rock is eroded. Intrusive igneous rock, however, is often quite resistant to erosion, and so remains in place.

Does a dome mountain form when rising magma is blocked by a horizontal layers of rock?
Yes, a dome mountain forms when rising magma is forced up towards the surface but encounters resistant horizontal layers of rock that prevent it from breaking through. As the pressure builds, the overlying rock layers are uplifted and arched, creating the characteristic dome shape.
What magma is silica-rich thick magma?
An acid magma or a granitic magma.
What is most magma?
magma
