How did the accretion process during the early formation of the Earth affect the characteristics of its interior today?

At the same time as the rest of the Solar System, Mars was formed from a large spinning disk of gas and dust. Astronomers think that this happened about 4.5 billion years ago. Mars is about 4.5 billion years old.

Are extrusive rocks fine grained?

Fine grained rocks are called "extrusive" and are generally produced through volcanic eruptions. Grain size can vary greatly, from extremely coarse grained rocks with crystals the size of your fist, down to glassy material which cooled so quickly that there are no mineral grains at all. How are fine grained rocks formed? If magma cools quickly, for example when basalt lava erupts from a volcano, then many crystals form very quickly, and the resulting rock is fine-grained, with crystals usually less than 1mm in size. If magma is trapped underground in an igneous intrusion, it cools slowly because it is insulated by the surrounding rock.

Regarding this, what do extrusive rocks look like?

Extrusive rocks are usually distinguished from intrusive rocks on the basis of their texture and mineral composition. Both lava flows and pyroclastic debris (fragmented volcanic material) are extrusive; they are commonly glassy (obsidian) or finely crystalline (basalts and felsites). How do you describe the texture of a rock? The texture of a rock is the size, shape, and arrangement of the grains (for sedimentary rocks) or crystals (for igneous and metamorphic rocks). Also of importance are the rock's extent of homogeneity (i.e., uniformity of composition throughout) and the degree of isotropy.


Which processes would change a sedimentary rock to a metamorphic rock quizlet?

King Triton has seven daughters. The Red Sea is named after Ariel. Attina is the Bering Sea, Adella is the Mediterranean Sea, Aquata is the Coral Sea, and Andrina is the Caribbean Sea.

Keeping this in consideration, why are intrusive rocks coarse grained and extrusive rocks fine-grained quizlet?

Intrusive igneous rocks form when magma cools and solidifies within Earth. Extrusive igneous rocks form when lava cools and hardens at the surface. Fine-grained igneous rocks form then lava cools quickly at Earth's surface. Regarding this, what is extrusive rock quizlet? Extrusive Rock. Extrusive rock is igneous rock, that is form by magma that is cooled very quickly over top of the earths surface. They have fine grain textures. The most common extrusive rock is basalt.

Consequently, how are extrusive rocks formed brainly?

Answer: Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground.
