BASALT: A common, dark-colored, fine-grained extrusive igneous rock, forming much of the Earth's oceanic crust.
PUMICE: A very light and porous volcanic rock formed when superheated, highly pressurized molten rock is violently ejected from a volcano.
SCORIA: A dark, vesicular volcanic rock with a bubbly texture, similar to pumice but denser.
GABBRO: A dark, coarse-grained intrusive igneous rock, chemically similar to basalt but formed underground.
7 Letters
GRANITE: A very common type of coarse-grained, intrusive igneous rock, widely used in construction due to its hardness and durability.
DIORITE: A coarse-grained, intrusive igneous rock, darker than granite but lighter than gabbro.
8 Letters
OBSIDIAN: A naturally occurring volcanic glass formed as an extrusive igneous rock.
RHYOLITE: A fine-grained, extrusive igneous rock, chemically equivalent to granite but formed at the surface.

More About "igneous rock crossword puzzle"
Igneous rocks are one of the three main rock types, alongside sedimentary and metamorphic. They are formed from the cooling and solidification of molten rock (magma or lava). This geological process creates a diverse range of rocks, each with unique characteristics and common names that frequently appear in crosswords. Recognizing these terms can give you a significant advantage when tackling puzzles.
Crossword clues related to igneous rocks often test your knowledge of specific rock types, their origins, or their common uses. Clues might refer to a "volcanic glass," "rock from cooled lava," or "granite's cousin." By familiarizing yourself with terms like basalt, granite, obsidian, and pumice, you'll be better equipped to quickly identify solutions. These words also often have specific letter counts that fit neatly into grids, making them popular answers for puzzle constructors.
Understanding the context of igneous rock formation can also help. For instance, extrusive igneous rocks form from lava on the surface, leading to fine-grained textures, while intrusive igneous rocks form from magma underground, resulting in coarser grains. This distinction, while technical, can sometimes be hinted at in clues, guiding you towards the correct answer and a quicker solve.
Tips For Your Next Puzzle
- Memorize Common Rock Types: Create a mental list or flashcards of common igneous, sedimentary, and metamorphic rock names frequently seen in crosswords (e.g., BASALT, GRANITE, SLATE, MARBLE). Having these on hand can significantly speed up your solve time.
- Look for Clue Specifics: Pay attention to adjectives or additional descriptors in the clue. "Volcanic" points to extrusive rocks like LAVA or PUMICE, while "intrusive" might suggest GRANITE or DIORITE. These details are often crucial hints.
- Consider Letter Lengths: If you have a few letters already filled in from intersecting words, use the remaining slots to narrow down possibilities from your rock vocabulary. The exact letter count of the answer is often your best hint for a specific word.
- Check Cross-References: Always use intersecting words to confirm your chosen rock answer. If one letter doesn't fit with an intersecting clue, your rock guess might be incorrect, or you've made a mistake elsewhere.

Frequently Asked Questions
What is an igneous rock?
An igneous rock is formed from the cooling and solidification of molten rock, either magma (below the Earth's surface) or lava (on the Earth's surface). Examples include granite, basalt, and obsidian.
Why do igneous rocks often appear in crosswords?
Igneous rocks provide a rich vocabulary of unique and often concise names (like TUFF, LAVA, BASALT, PUMICE) that fit well into crossword grids. They are also common knowledge topics, making them fair game for puzzles that aim to test general knowledge.
Are there other geological terms common in crosswords?
Yes, besides igneous rocks, crosswords frequently feature terms related to other rock types (sedimentary, metamorphic), geological processes (ERODE, FAULT, EROSION), and various landforms (MESA, BUTTE, ATOLL, GEYSER). Expanding your geology vocabulary can significantly boost your crossword success.
