Granite starts to weather as it nears the Earth's surface when the rock above it is weathered and eroded away, or from tectonic uplift. The granite expands from this depressurization and fractures into large blocks which begin to open it up to all weathering factors, such as freeze/thaw cycles, chemical weathering, and fluid hydraulics.

What has to happen to granite before water can pass through it?
Granite is typically impermeable to water due to its dense and compact structure. To enable water to pass through granite, the rock needs to undergo weathering processes, such as fracturing or chemical breakdown, that create fractures, joints, or pores in the rock that allow water to infiltrate. This can happen through natural weathering over time or through human activities like drilling or blasting.
What was slate before being metamorphosed?
Slate was originally a sedimentary rock called shale before undergoing metamorphism. Shale is a fine-grained rock formed from the compaction of mud and clay particles. Through the process of metamorphism, the shale is subjected to heat and pressure, which transforms it into slate.
When a granite intrudes into a layer of limestone which is younger granite or limestone?
When a granite intrusion occurs within a layer of younger limestone, the granite is considered older than the surrounding limestone. This is because intrusive rocks form before surrounding sedimentary rocks. If the intrusion occurs within older limestone, then the limestone is considered older than the granite.
What kind of geological feature is the exposed granite of Stone Mountain Georgia?
The exposed granite of Stone Mountain, Georgia is a type of igneous intrusion called a pluton. It formed underground from molten rock that slowly cooled and solidified before being exposed at the surface through erosion.
How far beneath the Earths surface would you have to go before you were no longer passing through rock that had the composition of granite?
On average, granite makes up the Earth's crust, which extends about 30-50 kilometers deep below the surface. So, you would need to go deeper than that to no longer pass through rock with the composition of granite. This depth can vary depending on the specific location and geologic setting.

How far beneath the earth's surface would you have to go before you were no longer passing through rock that had no composition of granite?
i think about 30 kilomiters
Is granite and basalt found in volcanoes?
Yes, both granite and basalt can be found in volcanoes. Basalt is a common type of volcanic rock formed from the rapid cooling of lava, while granite can be present in volcanic environments due to magma cooling and crystallizing beneath the Earth's surface before being exposed through volcanic activity.
How can I properly maintain and care for my granite countertops to ensure they remain in top condition, including the process of sealing granite?
To properly maintain granite countertops, clean them regularly with a mild soap and water solution. Avoid using harsh chemicals or abrasive cleaners. To ensure they remain in top condition, seal the granite every 1-3 years to protect it from stains and damage. This involves applying a granite sealer with a soft cloth and allowing it to dry completely before using the countertops.
What year did national weather service start naming storms before women?
1900s through 1953
Does Granite cools very quickly?
No. Granite cools relatively slowly; its large crystals are one method of observing this. Granite is referred to as a "phaneritic" igneous rock, meaning that it is coarse-grained. Coarse-grained rocks cool slowly, which means that the minerals have time to form large crystals before the rock solidifies. A rock with the same composition as granite that does cool quickly is called rhyolite.
When a granite intrudes into a layer of limestone which is younger granite or limestone?
When a granite intrusion occurs within a layer of younger limestone, the granite is considered older than the surrounding limestone. This is because intrusive rocks form before surrounding sedimentary rocks. If the intrusion occurs within older limestone, then the limestone is considered older than the granite.

How long does it take hay to go through heat?
Hay goes through a process called "curing" to reduce moisture levels before it can be baled and stored. The time this takes can vary depending on weather conditions, but typically it can take anywhere from a few days to a couple of weeks to properly cure hay. It's important to monitor the hay during this process to ensure it is fully dried before storing to prevent mold and spoilage.
How can I effectively remove rust stains from a granite counter?
To effectively remove rust stains from a granite counter, you can create a paste using baking soda and water, apply it to the stained area, and let it sit for a few hours before scrubbing with a soft brush. Rinse the area thoroughly with water and repeat the process if necessary. Avoid using harsh chemicals or abrasive cleaners that can damage the granite surface.
