Magma rises to the surface and cools, making igneous rock / the igneous rock is weathered and eroded, breaking it down/ sediments are deposited, creating sedimentary rocks / sedimentary rock piles up and gets pushed deeper, increasing temperature and pressure / changes to metamorphic rock / if pushed deeper it remelts and becomes magma again

Basalt vs Sandstone Characteristics. Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Basalt vs Sandstone characteristics assist .
Basalt is an example of a fine-crystalline rock that cooled rapidly at the surface of the earth. Igneous rocks can be thought of as the ultimate parent material for most soils. The igneous rock may have been ground up and transported innumerable times between when it first solidified and what we see today. ... Granite is an igneous rock that ...
The basalt came from deep within the earth as a fluid material, and because of pressure, was able to force the Conway granite aside. The basalt crystallized quickly against the relatively cold granite. Because of this quick cooling, the basalt is a fine- grained rock. Had this material ever reached the surface, it would have become lava flows.
Basalt is an easily datable rock and thus is a handy tool when available. Basalt flows emanating from the Uinkaret field between the Hurricane and Toroweep faults spilled into the Grand Canyon as shown in Figure 14.19. These basalts have been used to determine Colorado River incision rates.

The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. It wants to be there, and heat is the key which unlocks the door. As it turns out, most of the ocean floor is basalt, and most of the continents are granite. Basaltic crust is dark and thin and heavy, while granite is light and accumulates ...
Because it depends on the silica content in the lava or magma. Lava that is low in silica usually forms dark-colored rocks such as basalt. Magma that is high in silica usually forms light-colored rocks, such as granite.
Basalt Earth's Most Abundant Bedrock. Basalt and granite are both igneous rocks, meaning that they cooled from a magma. But the similarities start to diverge there. Granite forms from the slow crystallization of magma below Earth's surface whereas basalt forms as lava oozes toward the Earth's surface at a volcano or mid-oceanic ridge.
Basalt is one of the most common rock types in the world. Basalt is the rock most typical of large igneous provinces. The largest occurrences of basalt are in the ocean floor that is almost completely made up by basalt. Above sea level basalt is common in hotspot islands and around volcanic arcs, specially those on thin crust.
