Magma is injected into surrounding rock forming an igneous intrusive is the statement that best describe an igneous intrusion.

Photovoltaic modules, commonly called solar modules, are the key components used to convert sunlight into electricity. Light striking the crystals induces the “photovoltaic effect,” which generates electricity. The electricity produced is called direct current (DC) and can be used immediately or stored in a battery.

A magnifying glass (called a hand lens in laboratory contexts) is a convex or converging lens that is used to produce a magnified image of an object. The lens is usually mounted in a frame with a handle.

Water pipes burst because the water inside them expands is it gets close to freezing, and this causes an increase in pressure inside the pipe.
