Why is intrusive rock usually harder than extrusive rock?
Intrusive rock cools slowly beneath the Earth's surface, allowing larger mineral crystals to form, making the rock harder. Extrusive rock cools quickly on the Earth's surface, leading to smaller crystals and a softer composition.
What is a rock that is white and harder than chalk called?
A rock that is white and harder than chalk is likely to be marble. Marble is a metamorphic rock that is formed from limestone under high pressure and heat, making it harder and more durable than chalk, which is a soft sedimentary rock.
What rock is harder than sandstone?
Granite is typically harder than sandstone. Granite is an igneous rock that forms from the cooling of molten magma, making it more dense and resistant to abrasion compared to sandstone, which is a sedimentary rock.
Is bauxite harder than granite?
No, granite is harder than bauxite. Granite is a type of igneous rock that is known for its durability and hardness, while bauxite is a sedimentary rock that is softer in comparison.
How is an earth pillar formed?
An earth pillar is formed through a natural process of erosion, where softer sedimentary layers erode faster than harder rock layers, creating a tall, thin column of rock. Over time, the surrounding soil and softer rock erode away, leaving behind the more resistant pillar of harder rock. This process can take thousands to millions of years to occur.

How many Plutos can fit into the earth?
none Jupiter is larger than earth----Whilst it is true that Jupiter is large than the earth ( a lot larger!) it's not important hereAbout 170 Plutos would fit into the Earth (using the relative volumes to calculate)For completeness about 1320 Earths fit into Jupiter so 224400 Plutos would fit into Jupiter.Did we mention Jupiter is pretty big? And Pluto pretty small?
How are diamonds used in a rock drill?
A rock drill may be tipped with industrial diamonds, because the diamond tip makes the drill harder than the rock(s). Diamond is the hardest natural mineral on Earth.
What rock is harder than sandstone?
Granite is typically harder than sandstone. Granite is an igneous rock that forms from the cooling of molten magma, making it more dense and resistant to abrasion compared to sandstone, which is a sedimentary rock.
Is chalk harder than limestone?
No, limestone is harder than chalk. Limestone is a sedimentary rock composed mainly of calcite, whereas chalk is a soft, porous sedimentary rock composed mainly of calcium carbonate.
Is marble harder than basalt?
No, basalt is generally harder than marble. Basalt is a mafic extrusive rock that has a higher hardness and durability compared to marble, which is a metamorphic rock.
Why is intrusive rock harder than a extrusive igneous rock?
The rocks are underground so intrusive rocks are under pressure so its harder.
Is bauxite harder than granite?
No, granite is harder than bauxite. Granite is a type of igneous rock that is known for its durability and hardness, while bauxite is a sedimentary rock that is softer in comparison.

What is the second hardest natural substance on earth?
The hardest substance that is naturally occurring is a diamond. However, there are harder substances that have been made by scientists in labs.
Is rock Leone better than earth eagle?
there probably the same but i think rock Leone is better because its a really good attack type
