Answer:
When the magma, a molten rock flows as lava at the planet's surface, the surface gets cooled after a long, this whole process cause formation of some kinds of minerals on that surface.
Explanation:
Magma and Lava both are types of molten rock. The underground molten rock is called magma while the exploded molten rock on surface is known as lava. When these rocks cools down they get solidified and form crystal rock structure. Cooled magma is called plutonic igneous rock and cooled lava is called volcanic igneous rock. These rock crystals are of different sizes and consist several minerals such as Silicon(Si), Sodium (Na), Potassium (K), Aluminium (Al), Iron(Fe), Magnesium(Mg), Calcium(Ca). Some rocks that forms minerals consist high amount of iron. The amount of minerals and elements in every rock can very depending on shape and size.

The speed of a wave measures how far one particular crest (or trough) moves in a given amount of time. The speed of the wave changes according to the following equation:
v = λ
* f
According this equation, it follows that as the speed and length of a wave decreases, the wave grows higher (the higher the frequency).
