Extrusive igneous rocks are formed by cooling lava. Since
the temperature gradient between lava and Earth’s atmosphere is very big,
cooling is very rapid. The second option is deemed true, which also means the
third option is false. Foliations occur only in metamorphic rocks, deeming the
forth option false. Since extrusive igneous rocks are formed at the surface of
the Earth, there would be no confining pressure, which means the first option
is false.
Answer:
The solar system shows the planets in their orbits around the sun in this order: Mercury, Venus, Earth with Moon, Mars, Jupiter, Saturn. Fixed stars are around the outside of the orbit of Saturn.
Explanation:
Aristarchus of Samos was an ancient Greek astronomer and mathematician who presented the first known heliocentric model that placed the Sun at the center. So I had to choose the choice that was most similar to that.
Answer:
a. What are the most considerable impacts you make
Explanation:
- Earth is the only planet that is capable of life in the solar system and it provides a sustainable environment for life forms and the non-living forms and has constant recycle of the materials in the ecosystem and involves the following components as water, nitrogen and carbon and sulfur and the phosphorus and the elements that impact the lifestyle of these cycles are the how we sue the resources and there impacts on the on earth ecological systems.
This geological process is called Mantle drag .
What is Mantle drag?
According to the first driving mechanism, known as mantle drag, plate motion is the consequence of viscous drag brought on by the lateral motion of the tops of mantle convection cells in the asthenosphere on the base of the lithosphere . Convection cells would thus be mostly absent beneath continents, rising beneath oceanic ridges, and dropping beneath trenches. This idea states that the oceanic lithosphere would be in a state of tension at the ocean ridges and compression at the trenches.
Due to their connection to accretive and destructive plate boundaries, the horizontal widths of the convection cells causing mantle drag would be projected to be around half an ocean's breadth, or 3000 km.
