deposition
compaction/cementation and lithification changes sediments to sedimentary rocks. High pressure and temperatures changes them to metamophic rocks
the look and feel of sedimentary rocks are sometimes hard and smooth or hard and rough
harder than metamorphic
Metamorphic rock is generally hard, as it forms through the intense heat and pressure of metamorphism, which causes the minerals in the rock to recrystallize and align in a more compact and dense structure. This results in a rock that is usually more resistant to weathering and erosion compared to softer sedimentary rocks.
Arrowheads are typically made from harder rocks like flint, obsidian, or chert, which are not sedimentary rocks. These hard rocks were preferred for arrowhead-making because they can hold a sharp edge and withstand repeated use. Sedimentary rocks are generally too soft to be suitable for making arrowheads.
Yes, limestone is considered a hard rock. It is a sedimentary rock composed mainly of calcium carbonate minerals. While not as hard as igneous rocks like granite, limestone is still durable and commonly used in construction and as a building material.
The Earth's hard surface is primarily composed of rocks and minerals. These rocks can be classified into three main groups: igneous, sedimentary, and metamorphic rocks. Igneous rocks are formed from the cooling of molten magma, sedimentary rocks are formed from the accumulation and cementation of sediments, and metamorphic rocks are formed through the alteration of existing rocks under high pressure and temperature.
Hard matrix is supposed to be used for digging hard rocks and soft matrix for soft rocks. It's quite confusing to me
Both are composed of minerals. Some sedimentary rocks contain pieces of igneous rocks.
Sedimentary rocks are broken into two classes: clasticand chemical. Clastic sedimentary rocks are composed of rock particles, and chemical sedimentary rocks are composed of precipitation of minerals in solution.
Metamorphic, Igneous, and Sedimentary. Sedimentary is produced by river sediments compacted into hard rock by years of pressure. Igneous rock is formed by lava cooling down when it reaches the surface. Metamorphic rock comes from Igneous, Sedimentary, or other Metamorphic rocks and is defined as rock that has been changed from some other rock, called a protolith, by years of heat and pressure beneath the Earth's surface.
Gneiss is metamorphic rock that forms from preexisting sedimentary or igneous rocks. It is developed under high temperature and pressure conditions, causing it to become hard.
why do sedidimentary rocks have so many layers it is very hard rock and i think it is made of silicon
