1. To determine the answer, we need to understand the characteristics of different types of magma and their association with volcanic eruptions. One way to do this is to consider the composition of the magma.
- Basaltic magma is generally associated with effusive and relatively moderate eruptions.
- Andesitic and rhyolitic magmas are higher in silica content and tend to be more viscous, leading to explosive eruptions.
- Composite volcanoes, also known as stratovolcanoes, are typically associated with explosive eruptions.
By comparing the characteristics of the different types of magma, we can conclude that the correct answer is B. Rhyolitic magma causes powerful and explosive volcanic eruptions.
2. To determine the correct answer, we need to understand the processes involved in the formation of mountain ranges. One term used to describe these processes is orogeny. Orogeny refers to the collective set of processes that create and shape mountain ranges, such as tectonic plate movements, folding, faulting, and volcanic activity.
With this knowledge, we can conclude that the correct answer is C. Orogeny denotes all the processes that form mountain ranges.
3. To answer this question, we need to understand the various phenomena associated with the discharge of magma, hot fluids, ash, and gases. The term that encompasses all these processes is volcanism. Volcanism refers to the activity, processes, and phenomena related to volcanic eruptions and the release of materials from the Earth's interior.
Therefore, the correct answer is A. Volcanism describes all the processes associated with the discharge of magma, hot fluids, ash, and gases.
4. This question asks about the currents that facilitate the transfer of thermal energy. One type of energy transfer is convection, which involves the movement of fluids (e.g., air or water) due to temperature differences. This movement helps distribute heat from warmer regions to cooler regions.
Thus, the correct answer is D. Convection currents assist in the transfer of thermal energy from warmer climates to cooler climates.
5. To determine the answer, we must understand what soil liquefaction is and how it is related to seismic vibrations. Soil liquefaction occurs when saturated soil temporarily loses strength and behaves like a liquid due to the shaking or vibration caused by an earthquake or other seismic activity.
Based on this understanding, we can conclude that the correct answer is C. Seismic vibrations cause the ground to act like a liquid during soil liquefaction.
1. A. Andesitic magma causes powerful and explosive volcanic eruptions.
2. C. All the processes that form mountain ranges are known as orogeny.
3. A. Volcanism describes all the processes associated with the discharge of magma, hot fluids, ash, and gases.
4. D. Convection currents assist in the transfer of thermal energy from warmer climates to cooler climates.
5. C. Soil liquefaction occurs when seismic vibrations cause the ground to act like a liquid.
