What is the significance of limestone in the formation and characteristics of a river ecosystem?
Limestone plays a significant role in shaping river ecosystems due to its ability to dissolve in water, creating alkaline conditions that support diverse aquatic life. It also contributes to the formation of caves, cliffs, and waterfalls, which provide habitats for various species. Additionally, the presence of limestone can affect the water's pH levels and nutrient content, influencing the types of plants and animals that can thrive in the ecosystem.

Why is limestone referred to as the parent rock of marble?
Limestone is considered the parent rock of marble because marble forms from the metamorphism of limestone. Under heat and pressure, the mineral composition of limestone changes, resulting in the formation of marble. This transformation gives marble its distinct crystalline structure and unique appearance while retaining some of the original characteristics of limestone.
What type of climate would soil form fastest from limestone bedrock?
A warm and humid climate would lead to rapid soil formation from limestone bedrock. The combination of warmth, moisture, and chemical weathering would accelerate the breakdown of the limestone and the formation of soil.
The metamorphism of limestone results in the formation of?
The metamorphism of limestone results in the formation of marble. Marble typically forms when limestone undergoes intense heat and pressure deep within the Earth, causing its minerals to recrystallize into a harder, denser rock with a distinct appearance.
The formation of Karst topography requires carbonic acid to react with?
limestone
What happens when it rains on limestone?
When rain falls on limestone, a chemical reaction occurs causing the limestone to dissolve. This process is called carbonation and results in the formation of calcium bicarbonate, which can be washed away over time by the rainwater. As a result, limestone can be weathered and eroded by rainfall.
What is the gray bat's ecosystem?
in colonies within limestone caves
What rock is commonly weathered in cave formation?
Limestone.
What is the main cause for cave formation?
Dissolving limestone.

What would you find under Kaibab limestone if you were to drill a hole into the Kaibab limestone?
If you were to drill a hole into Kaibab limestone, you would likely find either Toroweap Formation or ancient sandstone layers beneath it. The Toroweap Formation usually underlies the Kaibab limestone in the Grand Canyon region.

Is limestone cave formation chemical or mechanical weathering?
chemical change
What reactions with water lead to the formation of caves with limestone?
The reaction of carbon dioxide in rainwater creates a weak carbonic acid, which dissolves limestone over time. This process, known as carbonation, leads to the formation of caves in limestone formations. Over thousands of years, the acidic water dissolves the limestone, creating underground tunnels and chambers.
What rocks are waterfalls made of?
The first hard layer is the Lockport Formation, which is made from limestone. The secound is softer, and is the Rochester Formation, and is made from shale and some very thin limestone bits. The third layer is underwater, and is Queenston Formation, which is made from shales and fine sandstone.
How are limestone caves different to other caves?
Primarily in their mode of formation: dissolution of limestone by water acidified by atmospheric CO2 (forming carbonic acid).
The formation of Karst topography requires carbonic acid to react with?
limestone
