How does water entering spaces in limestone cause physical weathering?
Mainly through expansion of cracks and fissures from frost expansion which leads to further and deeper cracks and fissures. Plant roots seeking moisture may extend roots into limestone cracks and fissures, prying the rock apart.
What are the cracks along flat rocks surfaces called?
The cracks along flat rock surfaces are commonly referred to as fissures or fractures. These cracks can occur due to natural processes like weathering, erosion, and tectonic forces. Over time, these cracks can widen and deepen, eventually leading to the breakage of the rock.
What are veins of gold found in rock called?
Veins of gold found in rock are typically referred to as gold veins or gold lodes. These are formed when hydrothermal fluids carry gold and deposit it in cracks and fissures within the surrounding rock.
How water could cause cracks to form in gritstone cliffs?
Water can penetrate the small pores in gritstone cliffs. When the temperature drops, the water freezes and expands, putting pressure on the rock and causing cracks to form. Over time, repeated cycles of freezing and thawing can widen these cracks, eventually leading to the formation of larger fissures and eventual crumbling of the rock.
What are some signs of weathering?
Some signs of weathering include cracks and fissures in rocks, rounding of sharp edges and corners of rocks, erosion of soil and rocks, and the formation of patterns on rock surfaces due to chemical or physical processes.
What are cracks formed in rock?
faults
Insects live in the metamorphic rock?
Insects can perform their life functions in and around the cracks and fissures of exposed weathered metamorphic rock.
What are large cracks that can allow melted rock to ooze out in a lava flow?
Large cracks in a lava flow where melted rock can ooze out are known as fissures. Fissures can result from the pressure buildup of magma beneath the surface, causing it to find weak points in the Earth's crust to escape from. These openings can lead to the formation of lava flows and volcanic eruptions.
Vein minerals are metal deposits that occur in the cracks of rocks?
Vein minerals can contain deposits of metals and other minerals, and occur in fissures or cracks of rock.

Mainly through expansion of cracks and fissures from frost expansion which leads to further and deeper cracks and fissures. Plant roots seeking moisture may extend roots into limestone cracks and fissures, prying the rock apart.
What are the cracks along flat rocks surfaces called?
The cracks along flat rock surfaces are commonly referred to as fissures or fractures. These cracks can occur due to natural processes like weathering, erosion, and tectonic forces. Over time, these cracks can widen and deepen, eventually leading to the breakage of the rock.
What words could be related to fissures?
Cracks, splits, openings, crevasses.
What is Magma injected into older rock?
That is known as an "intrusion". The magma (lava) is forced under pressure into cracks and fissures within the older rock. There are some good examples of this type of formation in Yellowstone caldera.
What are veins of gold found in rock called?
Veins of gold found in rock are typically referred to as gold veins or gold lodes. These are formed when hydrothermal fluids carry gold and deposit it in cracks and fissures within the surrounding rock.
What are cracks in the ocean crust that allows heat from the earth to escape?
They are called fissures.
Water often passes through beds of limestone because?
limestone is a permeable rock that allows water to flow through its cracks and pores. As water moves through limestone, it can dissolve the rock, creating caves, sinkholes, and underground rivers. This process is known as karstification.
Cracks in the ground that allow steam and gas to escape?
These are typically called fumaroles, and can occur along cracks or fissures in the ground.
