Arturiano [62]

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.

Based on the information in the chart, what can we conclude about the functionality of various sized beaks.
denis23 [38]

The correct answer is - B. Beak size determines what the bird can eat.

The beak of a bird can come in many different shapes and sizes. It can be pointy, long, short, rounded, scythe-like, thin, thick... All of those shapes and sizes have a specific role, and that role is to enable the bird to feed itself with certain type of food source. Every food source requires certain type of beak in order for the bird to be efficient in getting its nutrition, so depending on hat the bird eats, we can easily see a pattern in the beaks, where birds that eat nuts have one strong and shorter beak, the ones that eat warms and insects have thin, pointy one, the predator birds have claw like, sharp beak...
