some rocks are not always visable becasue it depends what the rock is made of. if it is a material of granite then it would be harder to see in the light since granite is a light sort of colour but if it is something like slate which is a darker colour it will blend in with the light on a dull day. so rocks are not always visable depending on the material and light in the day.
Rocks with visible crystals are classified as crystalline rocks. These rocks are formed when minerals inside the rock crystallize and grow to a size that they are visible to the naked eye. Examples include granite and basalt.
Igneus rocks.
Well the newest rocks are always on the top or on the most visible place - normally top or closest to the side somewhere. The newer rocks never are at the bottom of a rock, cave, or canyon
I dont know , thats wjy I asked
There are six visible rocks in the Club Penguin Forest.

== Grain size. Most intrusive igneous rocks will have visible crystals. Crystals in most extrusive igneous rocks are not easily visible.
Rocks with visible layers and elongated mineral grains are called foliated rocks. These rocks form under high pressure and temperature conditions, causing minerals to align in layers or elongate in a specific direction. Examples include schist and gneiss.
No. From some parts of the world it is NEVER visible.
no
no pollution is not alwys visible eg pollution from cars in highway is not visible but they pollute the environment
Heat is always present in the formation of metamorphic rocks.
