What else can I help you with?
Which two rocks are composed-primarily of quartz feldspar and clay minerals?
rock salt and conglomerate
Why are some rocks hard?
Rocks can be hard due to the presence of minerals such as quartz or feldspar, which have strong molecular structures. The arrangement of these mineral crystals and the binding forces between them contribute to the hardness of the rock. Factors such as pressure, temperature, and the cooling rate during formation can also influence the hardness of rocks.
Which rock has hardness of 10?
The only mineral with a hardness of 10 on Moh's scale is diamond.
What are the properties of rocks?
Rocks are solid aggregates of minerals. They can vary in color, hardness, texture, and composition depending on the minerals they are made of and how they were formed. Rocks can also be classified into three main types: igneous, sedimentary, and metamorphic.
Can magnetite scratch other rocks and minerals?
Yes magnatite does and it can be scratched by a nail Jk!
What factors contribute to the hardness of water?
The hardness of water is mainly caused by the presence of minerals like calcium and magnesium. These minerals dissolve in water as it passes through rocks and soil, leading to increased hardness. Other factors that can contribute to water hardness include the pH level and the presence of other minerals like iron and manganese.
How do chemicals contribute to weathering?
Chemicals react with rocks and minerals or dissolve rocks and minerals.
Are some rocks harder than other rocks?
Absolutely, based on the hardness of the minerals that compose them.
What scale is used to harness rocks and minerals?
the Mohs hardness scale
A scale used to measure the hardness of rocks?
The Mohs scale is used to determine the relative hardness of minerals.
What is the scratch table of rocks and minerals?
The scratch table is called the Mohs Scale of Mineral Hardness and measures the hardness of minerals in relation to the known hardest (diamond) and softest (talc) minerals.

What is the rock with hardness '10' on Moh's scale?
Rocks are made up of minerals, which can have varying levels of hardness. The only mineral to have a hardness of 10 is diamond.
Which rock has hardness of 10?
The only mineral with a hardness of 10 on Moh's scale is diamond.
What is the rocks hardness called?
The hardness of a rock is called its "Mohs scale hardness." This scale ranks minerals and rocks based on their scratch resistance, with diamond being the hardest at 10 and talc being the softest at 1.
What is a rock with hardness '10' on the mohs scale?
Rocks are made up of minerals, which can have varying levels of hardness. The only mineral to have a hardness of 10 is diamond.
