What causes icicles to form in a cavern?
Caverns that form in limestone areas, due to rain water dissolving the limestone over millions of years, produce stalactites and stalagmites. Stalactites are icicle-like rock formations of deposited limestone hanging down from the cavern's roof. Stalagmites grow upwards from the cavern floor, due to the limestone solution dripping on the floor from the roof. In some cases, the stalactite and stalagmite joins in the middle to form a column.
What hormone does the testes produce?
The testes produce the hormone testosterone.Testosterone
What occurs in a lime kiln?
A lime kiln is a kiln used to produce quicklime by the calcination of limestone (calcium carbonate). The chemical equation for this reaction is:CaCO3 + heat → CaO + CO2 This reaction takes place at 900°C (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around 1000°C (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime.
How does the paramecium produce waste?
it does not produce waist. it is only a living cell.
Can pair production produce in vacuum?
pair production can not produce in vaccum
What are the two processes that must take place to produce karst and related topography?
Karst topography is formed by the dissolution of soluble rocks like limestone and dolomite through the process of groundwater erosion, creating features like sinkholes and caves. This is followed by the deposition of dissolved minerals (e.g., calcite formations) in caves, resulting in unique karst landscapes with distinctive landforms.
Which type of rock was chemically weathered by acidic groundwater to produce ths features?
Limestone is the type of rock that is chemically weathered by acidic groundwater, leading to distinctive features such as karst landscapes, sinkholes, and caves. The acidic groundwater, often containing carbonic acid formed from carbon dioxide in the soil, dissolves the calcium carbonate in limestone, resulting in the erosion and creation of these geological formations. Over time, this process can lead to significant alterations in the landscape.
What is the full cycle of limestone?
The limstone cycle: 1. Limstone (CaCO3) - Heat limestone to produce quicklime 2. Quicklime (CaO) - Add a few drops of water to produce slaked lime 3. Slake lime (Ca(OH)2(s)) - Add excess water to produce Limewater 4. Limewater (Ca(OH)3(aq) ) - Bubble CO2 gas into limewater to produce limestone This is called a cycle because it happens again and again...
What type of chemical weathering is associated with limestone?
Limestone is primarily affected by carbonation, which is a type of chemical weathering where carbon dioxide in water reacts with limestone to produce calcium bicarbonate - a soluble compound that dissolves the rock over time. This process results in the erosion and dissolution of limestone formations.
Is the moon made of the same three kinds of rock as the earth?
No. Since the moon is not geologically active it cannot produce metamorphic rock and since it has no forces of erosion and deposition it cannot produce sedimentary rock. As a result, all the rocks on the moon are igneous
How do you conserve limestone?
To conserve limestone, it is important to limit activities that produce pollutants that can degrade the stone, such as acid rain and air pollution. Additionally, controlling water runoff to prevent erosion and avoiding activities that disturb the natural environment where limestone is found can help in its conservation. Engaging in sustainable quarrying practices and implementing restoration efforts in quarries can also contribute to limestone conservation.
What landforms do wind erosion and deposition form in deserts?
In deserts Abrasion and Deflation produce a number of distinctive landforms which include ventifcats, yadangs and zeugen. You can search for these 3 types of landforms which are created due to wind erosion.
How does changing the slope of the stream table produce different results?
Changing the slope of the stream table affects the speed and direction of water flow. A steeper slope creates faster water flow, which can result in more erosion and deposition. Conversely, a flatter slope slows down water flow, leading to less erosion and deposition. These changes in flow dynamics can cause differences in the shape and size of channels, as well as the amount and distribution of sediment carried by the water.
What gas does limestone produce when heated?
Calcium oxide
What do both weathering and erosion produce?
Both weathering and erosion produce changes in the Earth's surface by breaking down rocks into smaller particles. Weathering breaks down rocks in place without moving them, while erosion involves the movement of these smaller particles to new locations by various agents like wind, water, or ice.
What are the objects that produce sand?
Sand is typically produced by the erosion of rocks, such as granite, limestone, and sandstone. This erosion can be caused by natural forces like water, wind, and ice wearing down the rocks over time. The broken down pieces of rock are then carried and deposited by these forces, eventually forming sand.
What form of erosion can produce a smooth polished surface on rock?
Ice erosion can do this as can aeolian erosion (desert varnish).
