Explanation:
Igneous rock is formed when molten rock from underground moves to the surface.
There are three types of rock
1. Igneous rock: This is formed when molten rock (magma or lava) cools and solidifies.
2. Sedimentary rock: As the name implies, it is formed by the coming together of small particles such as gravel, sand, silt, or clay.
Metamorphic rock: This is a rock formed from existing rock. It is formed by the gradual disintegration of existing rocks caused by heat or pressure.
High tides and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth and its water to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides.

Explanation:
Nothing will happen to the octopus population if the number of snails decreased or extinct in the area because there are many other organisms on which octopus can feed. Octopuses feed on crabs, small fishes, clams, snails, and on other octopuses so if other food sources are available to Octopus so there is no effect on the Octopus population but if there is no other food source then the Octopus population will definitely decreases due to lack of food.
