Marrrta [24]3 years ago

Answer:

If the light bulb had never been invented, we would use natural sunlight as light during the day and fire or candles when we cannot see the sun. Since the light of candles is rather dim, most people would also sleep and wake up early, with the sun. The streets would be darker at night, even in urban areas.

Many other inventions that use the light bulb may not have been invented, or would be different. For example, our computer screens and television screens are forms of small light bulbs. Car headlights use light bulbs as well.

Granite is a type of intrusive igneous rock

Explanation:

An igneous rock formed from hot magma or lava cools, solidifies or crystallizes to form rocks.

Based on the rate of cooling of magma, igneous rocks can either be intrusive or extrusive.  

A slow cooling of the magma deep within the earth without reaching the surface of the volcano leads to the production of intrusive igneous rocks.

This slow cooling leads to crystallization forming large crystals visible to the eyes with a phaneritic texture.

Granite has the best phaneritic texture among intrusive igneous rocks. Granite crystals can be easily visualized and are constituted by minerals like white feldspar, black hornblende, translucent quartz, and platy black biotite.

Extrusive igneous rocks like basalt are formed from microscopic crystals from fast cooling of magma.
