A volcano with an empty magma chamber would be called a caldera
Explanation: During certain types of explosive eruptions, a volcano's magma chamber may empty enough for an area above it to subside, forming a type of larger depression known as a caldera.
Answer:
The correct answer is erosion
Explanation:
- Magmatism refers to the positioning of magma on the outer surface and within the layers of a terrestrial planet which on cooling solidifies into igneous rocks.
- Mechanical weathering is the process of breaking of big rocks into tiny or smaller pieces. It is basically a process of conversion of big rocks into sediments thus leading to the formation of soil.
- Chemical Weathering is the process of breaking down of big rocks into tiny pieces by chemical reactions instead of mechanical processes.
- Erosion is the process of removal of soil, sediments and dissolved substance from one location and transporting it to another location on earth crust.
- Metamorphism is the process of change in the structure or com[position of a rock by the action of pressure, temperature or other natural forces.
Mostly fractures than cleavage
<span>Guyots are seamounts that have built above sea level. Erosion by waves destroyed the top of the seamount resulting in a flattened shape. Due to the movement of the ocean floor away from oceanic ridges, the sea floor gradually sinks and the flattened guyots are submerged to become undersea flat-topped peaks.</span>
