Why are millets called coarse grains?
Millets are referred to as coarse grains due to their relatively larger seed size and tougher husk compared to finer grains like wheat and rice. They are often less refined, retaining more of their nutrients, fiber, and minerals, which contribute to their classification as coarse. Additionally, their hardiness and adaptability to diverse growing conditions make them more resilient, further emphasizing their classification as coarse grains.
Where do rocks with coarse texture form?
Rocks with coarse texture typically form deep below the Earth's surface in the magma chamber of a volcano or in the mantle. As the molten rock cools slowly over time, large mineral grains have the opportunity to grow, resulting in a coarse texture. This process allows for the formation of rocks like granite or pegmatite.
Is quartzite course grained or fine grained?
Quartzite is typically coarse-grained, with individual grains visible to the naked eye. This is because quartzite is formed by the metamorphism of sandstone, where the original sand grains recrystallize into larger grains.
What type of grains does metamorphic rock have?
Metamorphic rocks can have various types of minerals, such as quartz, feldspar, mica, and amphibole, which form grains within the rock. These grains can be elongated or flattened, depending on the degree of metamorphism the rock has undergone. The size, shape, and alignment of these grains provide valuable information about the rock's history and the conditions under which it formed.
What tool do you use to examine grains in a rock?
A petrographic microscope is commonly used to examine grains in a rock. This specialized microscope allows geologists to view minerals and their characteristics in thin sections of rocks at a microscopic level. By analyzing the grains and textures present, geologists can determine the rock's composition and origin.

What is coarse grain in metals?
Fine grains are harder than coarse grains
They are also known as coarse grains they can be grown on less fertile and sandy soil?
Millets are known as coarse grains that can be grown on less fertile and sandy soil.
What does coarse grained mean?
Jowar, Bajra, Ragi like millets is known as coarse grains.
What type of grains does an intrusive rook have?
An intrusive rock typically contains coarse-grained minerals, such as feldspar, quartz, and mica. These minerals were able to grow larger due to the slow cooling process of intrusive rocks beneath the Earth's surface.
When all the grains in a rock are easy to see the rock is described as what?
Visible crystals or grains would be referred to as a coarse grained texture.
