What is the best clue to tell in extrusive igneous rocks from in instrusive igneous rock?
Extrusive igneous rocks have smaller crystals due to rapid cooling on the Earth's surface, while intrusive igneous rocks have larger crystals due to slower cooling beneath the Earth's surface. This difference in crystal size can help distinguish between the two types of rocks.
What 3 rocks on the earth?
I'm going to tell you right now there are a lot more than three rocks on earth. However, there are only three basic TYPES of rocks, and those are Sedimentary, Igneous, and Metamorphic.
What type of rocks are metmorphic rock?
Metamorphic rocks are formed by the transformation of pre-existing rock types, such as igneous or sedimentary rocks, through heat, pressure, or chemically active fluids. Examples of metamorphic rocks include marble, slate, and quartzite.
Is metamorphic rock the oldest type of rock?
slate
What type of rocks are banded or non banded?
Well, friend, banded rocks are often made up of layers of different materials, like sedimentary rocks such as sandstone or shale. Non-banded rocks, on the other hand, can include igneous rocks like granite or basalt, which are formed from cooled magma without distinct layers. Both types of rocks have their own unique beauty and story to tell in the great tapestry of the Earth.

How can you tell rocks apart?
Rocks can be classified based on their texture, color, mineral composition, and how they formed. Identifying features like grain size, layering, and crystal shape can help distinguish between different types of rocks such as sedimentary, igneous, and metamorphic. In addition, conducting simple tests like scratching with a nail or testing for fizzing with acid can further assist in identifying rock types.
How can you tell igneous rocks apart?
Igneous rocks can be classified based on their texture and mineral composition. Texture is determined by the size of the mineral grains, with coarse-grained rocks forming from slow cooling and fine-grained rocks forming from rapid cooling. Mineral composition can also help differentiate igneous rocks, such as identifying the presence of minerals like quartz, feldspar, or olivine.
What do the large crystals in igneous rocks tell about the rock?
That it cooled very slowly.
Why are the extrusive and intrusive appropriate for the two types of igneous rocks?
because you can tell them more easily
How do we classify rock?
PYROCLASTIC ROCKS AND TEPHRA, Pyroclasts .
How can you tell the difference between an igneous rock that formed above ground and one that formed below?
Igneous rocks that form below ground (intrusive) have larger crystals due to slower cooling, whereas igneous rocks that form above ground (extrusive) have smaller crystals or a glassy texture due to rapid cooling. Additionally, intrusive rocks may show visible layering or bands, while extrusive rocks typically have a more uniform appearance.
How you can tell an igneous rock from a sedimentary rock from a metamorphic rock?
Igneous rocks form from the cooling and solidification of molten rock (magma/lava), sedimentary rocks form from the deposition and lithification of sediment particles, and metamorphic rocks form from the alteration of pre-existing rock due to heat and pressure. Igneous rocks often have a crystalline texture, sedimentary rocks may contain layers or fossils, and metamorphic rocks often have foliated or banded textures.
How are metamorphic rocks formed Tell it in a way that a grade 4 can understand it?
Basically a bunch of rocks come together( are pressed together by heat and pressure) in a process called Lithification , those rocks can be either Sedimentary or Igneous rocks.
What 3 rocks on the earth?
I'm going to tell you right now there are a lot more than three rocks on earth. However, there are only three basic TYPES of rocks, and those are Sedimentary, Igneous, and Metamorphic.
What is the relationship between an igneous rocks texture and where it formed?
The relationship between an igneous rock's texture and where it was formed is that the texture depends on whether or not the rock is an extrusive rock or an intrusive rock. Those two different types of classifications for rocks tell you what the texture will be. For example, Intrusive rocks have a coarse-grained texture like granite and extrusive rocks have a fine-grained texture like basalt.
