What else can I help you with?
Does sandstone weather faster than granite?
Because granite forms instrusively. Under the ground so they cools slow and that's why they have large crystals. Basalt froms extrusivelt. They cools so fast and that's why they have small crystals than granite
Is Basalt rock Igneous Rock?
yes
What rock comes directly from magma?
Igneous rocks like basalt and granite are formed directly from magma cooling and solidifying.
How can a basalt flow cause opal to form?
If the basalt flow contains air bubbles and pockets and there is a spring that contains silica then the silica can deposit into the air bubbles (the air bubbles are known as Amygdaloidal basalt or vesicles) If the silica deposits slowly and the conditions are correct then precious opal can form. Two examples of this would be in California at the Nowak and the Barnett mines.
How could you differentiate between marble and white quartz?
Marble will effervesce in vinegar or diluted hydrochloric acid--quartzite will not. Both quartzite and marble are meta-sedimentary rocks. However, quartzite comes from a quartz rich sandstone, and marble comes from limestone.White marble is white limestone that has gone through metamorphosis.White Quartzite is white sandstone that has gone through metamorphosis.
What rocks comes before quartzite in the rock cycle?
Quartzite is sandstone (sedimentary rock) that has metamorphosed from heat and pressure.
What is the origion of basalt?
it comes from magma inside the volcanoes then it cools and it turns in to basalt
What colors are sandstone?
sandstone is usually like a tannish or brown color.
From what rock is sandstone formed?
Sandstone is formed of layers of eroded rock grains deposited in shallow seas. Under immense pressure, the grains eventually become sandstone. Sandstone comes in many colors. Red sandstone is colored by iron oxide.
What kind of lava comes from Mt Fuji?
basalt lava
Is igneous rocks basalt?
Yes, basalt is an igneous rock. it comes from when the volcano erupts. it is the hardened lava. a main factor is silica.
How does quartzite form?
Quartz crystals typically grow hydrothermally, in hot, pressurized, silical solutions.
Describe how the granite of a mountain could change first into sandstone and then into quartzite?
Weathering causes the granite to break down into small particles - sand. The sand becomes buried and compacts into sandstone. If the sandstone continues to be buried and comes into close contact with high heat, such as magma, it can be turned into quartzite.
Describe how the granite of a mountain could change first into sandstone and then into quartize?
First of all, the granite erodes. This means the original rock breaks down due to weathering. Wind, water, ice, they can all do that. As the rock breaks down into smaller and smaller parts, it eventually turns into sand. The sand is then deposited somewhere (let's say a beach), and then buried under more sand. As more and more layers of sand get on top of the original sand, there is more pressure, and eventually, the pressure becomes big enough to turn the sand into sandstone. But the process of sedimentation doesn't stop, and after enough time, there is enough pressure to deform the sandstone. This is where metamorphism enters the stage. As more and more pressure is added, the volume of the sandstone decreases. Now, there are different ways in which the volume of something can be decreased. That is removing the empty space, and putting the atoms in a crystalline texture. As the sand originally comes from granite - which is a very silica rich rock - there will be a lot of silica in the sandstone. The crystal that forms then, will be largely silica. Pure quartz is 100% silica. So if the sandstone that we have starts to form crystals to decrease it's volume under pressure, we get the quartzite.
What rock is melted by heat and pressure?
Magma is rock that useally comes from a volcana it melts due to the high pressure and heat
Is Basalt rock Igneous Rock?
yes
