sry boo idk the answer im looking for it to hope you got the answers you were looking for happy new years<3
1. To answer this question, we need to understand the different types of magma and their effect on volcanic eruptions.
Andesitic, rhyolitic, and basaltic magmas are the three main types of magma. Andesitic and rhyolitic magmas have a higher silica content, making them more viscous and prone to explosive eruptions. Basaltic magma, on the other hand, has a lower silica content and flows more easily, resulting in less explosive eruptions.
To determine which type of magma causes powerful and explosive volcanic eruptions, we can eliminate options C (basaltic) and D (composite).
So, the correct answer is A. Andesitic magma causes powerful and explosive volcanic eruptions.
2. To answer this question, we need to understand the processes that form mountain ranges.
The term used to describe all the processes that form mountain ranges is orogeny. Orogeny refers to the geological processes, such as tectonic plate subduction, collision, and crustal deformation, that result in the formation of mountain ranges.
Therefore, the correct answer is C. Orogeny.
3. To answer this question, we need to understand the processes associated with the discharge of magma, hot fluids, ash, and gases.
The term used to describe all these processes is volcanism. Volcanism encompasses the movement of magma within the Earth's crust, its eruption onto the surface, and the release of volcanic gases, ash, and other materials.
Therefore, the correct answer is A. Volcanism.
4. To answer this question, we need to understand how thermal energy is transferred in different environments.
Convection currents are responsible for the transfer of thermal energy from warmer to cooler climates. Convection occurs when a fluid, such as air or water, heat up, become less dense, and rise, while cooler fluid sinks. This process creates circulation patterns that help distribute thermal energy.
Therefore, the correct answer is D. Convection.
5. To answer this question, we need to understand what soil liquefaction is and its cause.
Soil liquefaction occurs when seismic vibrations (earthquakes) cause saturated soil to temporarily lose its strength and behave like a liquid. This phenomenon happens when the water pressure between soil particles increases during shaking, reducing the friction that holds the particles together.
Therefore, the correct answer is C. Seismic vibrations cause the ground to act like a liquid.
