The focus is the place inside Earth's crust where an earthquake originates. The point on the Earth's surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions.
The extrusive igeous rock cools very fast and is made by lava, but because it cools so fast extrusive igneous rocks they have really small crystals. Now the intrusive igneous cools really slow beneath the surface, and is made by magma.

Answer: open</h2>
The image represents an open star cluster.
Open star clusters are groups of stars formed from the same molecular cloud, generally asymmetric (without structure).
An important characteristic of this type of cluster is that all its stars have the same age and similar chemical composition. In addition, they are linked to each other gravitationally, but to a lesser extent than those of globular clusters.
The stars hosted by these clusters tend to be young, massive and very hot.
Among this group are the Pleiades (represented in the image), located in the constellation of Taurus.
Sonar (sound navigation and ranging) is a technology that uses acoustical waves to sense the location of objects in the ocean.
