In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys.
Answer:
Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, this way warming the rocks. As the rock's temperature rises due to move from one place to another of heat by something touching something else, it then conducts to the rest of the earths surface, thus warming it up.
Explanation:
Answer:
1- Option (C)
2- Option (A)
3- Option (D)
Explanation:
- The magma within the earth's crust are often comprised of various types of materials and dissolved gases. The gases that are commonly present in magma are Water vapor (H₂O) and Carbon dioxide (CO₂). These gases gradually expand and forms bubbles, as the magma rises up and pressure eventually decreases. Some of the gases are escaped into the atmosphere, whereas some remains.
- The pyroclastic flow refers to those materials that are mixed up with rock fragments, volcanic ash and hot air, and that gradually flows along the slope of the volcano. During an explosive volcanic eruption, these materials are ejected and are spread to distant places.
- Calderas are the large crater-like depressions that form due to the subsidence of the mouth of a volcano or due to the eruption of a huge volcano leaving a large bowl-shaped depression. The materials that are present at the apex portion of these volcanoes are mostly comprised of volcanic rocks and tuffs that eventually get collapse.
Hence, the correct answers are mentioned above.
