Ah, a classic. It is porphyritic. The classic example is granite.
The rock is called porphyry, which forms when magma slowly cools beneath the Earth's surface. The large crystals are known as phenocrysts, and the smaller surrounding crystals are called groundmass or matrix.
a porphyritic rock. This texture indicates that the rock underwent two stages of cooling: slow cooling deep underground (resulting in the large crystals) followed by faster cooling near the surface (resulting in the small crystals).
Small crystals are called microcrystals. These tiny structures are often too small to be seen or examined without the aid of a microscope.
trichromes are the small cyrstals on marijuana buds.yummy!!
Igneous rocks with large crystals are called intrusive rocks, formed from magma cooling slowly beneath the Earth's surface, allowing for large crystals to form. Igneous rocks with small crystals are called extrusive rocks, formed from lava cooling quickly on the Earth's surface, resulting in small crystals due to rapid cooling.
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
It stinks, it has hairs on it. And it has small white crystals called keif on it.
A small one is called an island and a large one is called a continent.
A pond or a lake or a puddle.
its Djibouti
A large area of land which is completely surrounded by water is a continent. A small area of land which is completely surrounded by water is an island.
most minerals have a distinctive crystal arrangement. those minerals that do not have their atoms arranged in crystals are called amorphous minerals.
