What Igneous rocks have large crystals and form when melted rock cools slowly and hardens underneath earth's surface?
They are called intrusive igneous rocks.
Can A rock with visible layers and no mineral crystals likely formed by lava hardening on earths surface?
No, a rock with visible layers and no mineral crystals likely did not form from lava hardening on Earth's surface. Such layered rocks are typically sedimentary, formed from the accumulation and compaction of sediments over time. In contrast, igneous rocks formed from lava cooling often contain visible mineral crystals, as the cooling process allows crystals to grow.
When melted rock cools and hardens an intrusive igneous rock is formed?
when it cools undera lot of pressure underground it is an intrusive igneous. If it cools on the surface of the earth then it is an extrusive igneous.
What do atoms accumulate on during mineral growth?
Atoms accumulate on the surface of pre-existing mineral crystals or other solid surfaces during mineral growth. This process involves the deposition of ions and molecules from a solution onto the surface, leading to the formation of new mineral layers.
What igneous rock has crystals that are not visible?
Extrusive igneous rock consists of mineral crystals that are not observable with the naked eye. Obsidian is an extrusive igneous rock (volcanic glass) where there technically are no mineral crystals.
What type rock forms when magma cools and hardens?
Igneous rock forms when magma cools and hardens. This type of rock can be classified as intrusive (plutonic) if it cools below the Earth's surface (slow cooling) or extrusive (volcanic) if it cools quickly on the Earth's surface. Examples of igneous rocks include granite, basalt, and obsidian.
A mineral specimen has very small crystals What is the best explination for how this happened?
The mineral cooled rapidly on earth's surface

Igneous rocks that have mineral crystals easily seen with the unaided eye formed?
Igneous rocks that have mineral crystals easily seen with the unaided eye formed from slow cooling and crystallization of magma deep underground or at the Earth's surface. The slower the cooling process, the larger the mineral crystals can grow, resulting in rocks like granite and diorite with visible crystals.
When melted rock cools and hardens an intrusive igneous rock is formed?
when it cools undera lot of pressure underground it is an intrusive igneous. If it cools on the surface of the earth then it is an extrusive igneous.
When melted rock cools or hardens in or under earth surface it forms to what?
When melted rock cools and hardens in or under the Earth's surface, it forms igneous rock. This process can happen above ground, forming volcanic rocks, or below ground, forming intrusive rocks.
A mineral specimen has very small crystals what is the best explanation for how this happened?
The small crystals likely formed due to rapid cooling of the molten rock or solution from which the mineral precipitated. This rapid cooling did not allow enough time for the crystals to grow larger, resulting in the formation of small crystals.
What do atoms accumulate on during mineral growth?
Atoms accumulate on the surface of pre-existing mineral crystals or other solid surfaces during mineral growth. This process involves the deposition of ions and molecules from a solution onto the surface, leading to the formation of new mineral layers.
How do crystals form on plant leaves?
Crystals form on plant leaves when water containing minerals evaporates, leaving behind solid mineral deposits. These deposits accumulate over time, forming crystals on the surface of the leaf.
What igneous rock has crystals that are not visible?
Extrusive igneous rock consists of mineral crystals that are not observable with the naked eye. Obsidian is an extrusive igneous rock (volcanic glass) where there technically are no mineral crystals.
Is how light is reflected off a mineral's surface?
The way light is reflected off a mineral's surface is determined by its crystal structure and chemical composition. The specific orientation of the mineral's crystals affects the angles at which light is reflected, resulting in different luster and color characteristics. A mineral's surface can appear metallic, glassy, pearly, silky, or dull based on how light interacts with it.
