Let’s discuss the question: describe how the granite of a mountain could change. We summarize all relevant answers in section Q&A of website Abettes-culinary.com in category: MMO. See more related questions in the comments below.
How does granite change over time?
Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss.
How does granite change into sandstone?
Slowly, water and weather wore away granite through the process of erosion. These granite particles became sand, carried by streams to the ocean. Over millions of years, layers of sandy sediment piled up on the ocean floor. Slowly, the sediments were pressed together and cemented to form sandstone, a sedimentary rock.

How does granite change into a sedimentary rock?
Granite forms from solidified silicic magma within the Earth’s crust. It can be exhumed (brought toward the surface through erosion of the rock layers above and uplift through faulting). Once the granite is exposed it is subject to weathering and erosion, linking to the sedimentary part of the rock cycle.
What does granite turn into after weathering and erosion?
1 Answer. If it is part of a mountain, it gets weathered, eroded and transported to the ocean. If the granite gets buried deep in the crust it often changes to a gneiss.
How the granite of a mountain could change first into sandstone and then into quartzite?
Igneous rock granite formed beneath the surface millions of years ago. Then, the forces of mountain guilding slowly pushed the granite upward, forming a mountain. … Heat and pressure changed the rock’s texture from gritty to smooth. After millions of years, the sandstone changed into the metamorphic rock quartzite.
What are two changes granite could undergo as a next step in the rock cycle?
Granite can be brought toward the surface through soil erosion involving the rock layers above and raised by faults. Once the granite is brought on the surface, it can undergo weathering and erosion.
How does granite form?
Granite is formed when viscous (thick/ sticky) magma slowly cools and crystallises long before it is able to reach the Earth’s surface.
What step in the rock cycle would be required to change granite?
| QUESTIONS | ANSWERS |
|---|---|
| 3. What is the name of sedimentary rock that is made up of rounded fragments? | Conglomerate |
| 4. What step in the rock cycle would be required to change granite into sandstone? | Weathering and Erosion followed by compaction and cementation |
| 5. How do geologists classify metamorphic rock? | Arrangement of the grains |
How can igneous rock like granite be changed to a sedimentary rock like sandstone?
Weathering (breaking down rock) and erosion (transporting rock material) at or near the earth’s surface breaks down rocks into small and smaller pieces. These smaller pieces of rock (such as sand, silt, or mud) can be deposited as sediments that, after hardening, or lithifying, become sedimentary rocks.
How does the earth convert granite into a soil?
Soil is formed through the process of rock weathering. Weathering is the breakdown of rocks into smaller particles when in contact with water (flowing through rocks), air or living organisms.
How does granite travel?
Granite starts its journey potentially thousands of miles below the earth’s surface as magma. As this magma gains in pressure & rises through the cracks of the earth’s crust over time – it cools, & the granite is formed. In order to collect the stone from within the earth – it needs to be mined.

What are uses of granite?
It is widely used for architectural facades, construction materials, ornamental stone and monuments. Over 40% of dimension stone quarried is granite. Crushed granite is used as a durable construction material in asphalt and concrete used in highway and infrastructure projects.
What happens when granite weathers?
Wind. Wind, water and ice denude the soil and Earth’s crust overlying the granite mass, exposing it to the atmosphere. The rock expands and contracts in reaction to changes in temperature. It shatters on the surface and the fractures widen to form crevices.
How does granite change into quartzite?
The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly intergrown with each other, resulting in very hard and dense quartzite.
What rock is formed when quartz sandstone undergoes a metamorphism?
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures.
How does sandstone turn into quartzite?
Quartzite forms when pure or nearly pure quartz sandstone undergoes heating and pressure. Usually this is caused by tectonic compression. The sand grains of sandstone melt and recrystallize, cemented together by silica. Quartzite arenite is the intermediate stage between sandstone and quartzite.
What can happen to a granite that undergoes weathering?
What happens when granite is weathered? The biotite and/or amphibole will undergo hydrolysis to form clay, and oxidation to form iron oxides.
How did the granite end up at the bottom of the ocean?
Earth’s climate was much cooler then. And enormous ice caps stretched far from the North and South poles. Rondi: How did you end up at the bottom of the ocean? Granite: When the glacier finally started to melt, it dropped me and I sunk to the deep-sea floor.
Which processes would cause granite an igneous rock to form schist a metamorphic rock?
Which processes would cause granite an igneous rock to form schist a metamorphic rock? The heat generated by the magma chamber has changed these sedimentary rocks into the metamorphic rocks marble, quartzite, an hornfels. Regional Metamorphism occurs over a much larger area.
How would you describe granite?
granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth’s crust, forming by the cooling of magma (silicate melt) at depth.

How are granite boulders formed?
Over time, the sandstone eroded away exposing the granite, which then weathered into soft sand and clay surrounding hard bits of granite called corestones. Gradual removal of the soft sand and clay has exposed the rounded boulders, allowing them to be perched on top of one other.
How is granite igneous rock formed?
Granite is an intrusive igneous rock, which means it was formed in place during the cooling of molten rock. Generally, the slower the molten rock cooled, the larger it’s mineral crystals with K-Feldspar megacrysts forming in special circumstances greater than 5cm.
