Rocks with medium-sized crystals, like rock A, are typically formed through the process of slow cooling of magma or lava beneath the Earth’s surface, allowing crystals to grow to a moderate size. This process occurs in intrusive igneous rocks, where the magma cools slowly in the Earth's crust. As the temperature decreases, minerals crystallize out of the molten rock, resulting in the formation of visible, medium-sized crystals. Examples of such rocks include granite and diorite.

What is a medium sized tephra called?

A medium-sized tephra fragment is typically called lapilli. These fragments are between 2 and 64 mm in size and are formed during explosive volcanic eruptions.


What does the rate of cooling determine about igneous rocks?

The rate at which a rock cools will determine its grain or crystal size. Igneous rocks are widely classified into volcanic, hypabyssal and plutonic. Those that cool deep inside the earth are plutonic and those that cool and crystallize at or much near the Earth's surface are volcanic. The intermediate rocks are the hypabyssal ones. Volcanic rocks come immediately in contact with air or water and get quenched developing finer grained crystals that are best identified under a petrological microscope or a high power electron microscope. But plutonic rocks have a hell lot of time to cool due to their hotter surroundings resulting in well grown big crystals, which can usually be identified by naked eye or with the help of a hand lens. You should have now guessed the hypabyssal rocks will have medium sized crystals.


What is the material from which rudaceousis formed?

Rudaceous sedimentary rocks are formed from the accumulation and lithification of coarse-grained fragments such as gravel, cobble, and boulder-sized particles. These fragments are typically derived from the erosion and weathering of pre-existing rocks.


What are the different sediment rocks?

Some common types of sedimentary rocks include sandstone, limestone, shale, and conglomerate. Sandstone is made up of sand-sized mineral particles, limestone is composed of calcite or aragonite minerals, shale is formed from clay-sized particles, and conglomerate consists of rounded gravel-sized particles.


What are medium sized flat topped elevation?

Medium sized flat-topped elevations are called plateaus. Plateaus are elevated flatlands often found at higher altitudes, characterized by their relatively flat surface on top. They can be formed by geological processes like erosion, volcanic activity, or tectonic uplift.

Rocks such as sandstone which are formed from particles of other rocks are?

Sedimentary rocks. Sandstone is a common example of a sedimentary rock that is formed from the accumulation and cementation of sand-sized grains of mineral and rock fragments.

Do lava rocks usually have large grains?

Lava rocks typically have fine to medium-sized grains due to their rapid cooling process when formed from molten lava. Large grains are less common in lava rocks than in other types of igneous rocks that cool more slowly beneath the Earth's surface.
