The correct answer is B. Extrusive Igneous
Explanation
The image shows an image of an Obsidian rock and at the top a text fragment that says "The photo below shows a sample of Obsidian forms when lava from a volcanic eruption cools very quickly aboveground"
Igneous rocks are a group of rocks that includes all those that have been formed by the solidification of magma or lava expelled from the earth's lithosphere through a process called crystallization. In general, when the solidification of magma occurs within the lithosphere, the resulting rock is called intrusive. On the other hand, if the cooling occurs (at least in part) at the surface or a shallow depth, the resulting rock is called extrusive.
Taking into account the text that complements the image of the question and the previous information, it is possible to affirm that the correct answer is B. Extrusive Igneous because the rock is the result of the solidification of lava above the ground.
The correct answer is A. Heliocentric theory
Explanation:
Galileo Galilei was an Italian astronomer, mainly known for his observations that led Galilei to conclude planets revolve around the Sun (Heliocentric theory) instead of the sun and other planets revolving around the Earth (Geogcentrict theory). One of the observations that make Galilei drew this conclusion were telescopic observation of Venus, in this Galieli noticed similar to the moon Venus had different "phases" or changed its size and lighting, which was only possible if the sun was in the center of the solar system and planets revolve around it including the Earth. Thus, that Galileo was Venus changing size proved the Heliocentric theory.
The thick layer is the-crust
If air pressure rises, a high pressure cell is on the way and clear skies can be expected. If pressure falls, a low pressure cell is coming and will likely bring storm clouds. Barometric pressure data over a larger area can be used to identify pressure systems, fronts, and other weather systems.
