Final answer:
When lava and ocean water interact, it can lead to the formation of igneous rocks, tsunami generation, hydrothermal vent formation, and the creation of volcanic islands.
Step-by-step explanation:
When molten lava comes into contact with ocean water, several things can happen:
- Formation of igneous rocks: When lava cools and solidifies, it forms igneous rocks. This is a common occurrence when lava flows into the sea and solidifies to create new rock formations.
- Tsunami generation: The rapid cooling of lava when it comes into contact with cold ocean water can cause explosive steam eruptions, potentially leading to a tsunami.
- Hydrothermal vent formation: The interaction between lava and cold water can create cracks and fissures where heated water escapes, forming hydrothermal vents.
- Creation of volcanic islands: Over time, repeated volcanic eruptions and the accumulation of solidified lava can lead to the formation of volcanic islands.
