Limestones are made from fragments of sea creatures that sank to the bottom of ancient tropical seas. Many limestones from Southern England are made from dissolved lime which builds up around sand grains to form tiny spheres called oolites. Limestones frequently contain fossils. Here we see a stalactite from the limestone cave system a few miles away in Ingleton.

Describe how rocks are broken naturally broken down into smaller pieces?
Rocks are naturally broken down into smaller pieces through a process called weathering. This includes physical weathering, where rocks are broken apart by factors like ice, wind, and water, as well as chemical weathering, where rocks are broken down by reactions with substances in the environment. Over time, these processes cause rocks to fracture and crumble into smaller particles.
What makes rocks on mountain tops weather faster than rocks in valleys?
Rocks on mountain tops are exposed to harsher weather conditions, such as wind, rain, and ice, which can break down the rocks more quickly through processes like frost wedging and erosion. Additionally, mountain rocks may experience larger temperature variations, leading to thermal stress that can contribute to faster weathering.
Are big rocks broken into smaller rocks?
Yes, big rocks can be broken into smaller rocks through natural processes like weathering and erosion, where factors like wind, water, and temperature changes cause the rock to break down into smaller pieces over time. Additionally, human activities such as mining and quarrying also break big rocks into smaller rocks for various purposes.
What type of rock when rocks are broken down into smaller fragments?
Rocks are broken down by physical or chemical weathering.
Why rocks are broken down?
Rocks are broken down through a process called weathering, which can be caused by physical factors (such as wind, water, and ice) or chemical factors (such as acid rain and plant roots). Over time, weathering breaks rocks into smaller pieces through erosion, creating sediment that can be transported by natural processes like water or wind.
How are rocks at the top of the mountain different from ones on the bottom?
Rocks at the top of the mountain are often exposed to harsher environmental conditions like wind, ice, and extreme temperatures, leading to weathering and erosion. These rocks may be smaller in size and more broken down compared to rocks at the bottom which are protected and less affected by these factors. Additionally, rocks at the top may be more prone to being shifted by gravity and slope processes.
What is nonclastic rock?
clastic rocks are rocks that are broken off other rocks or sediments of rocks and come from many rocks through erosion nonfoliated is the opposite
How can rocks be broken into sediment through natural processes?
Rocks can be broken into sediment through natural processes like weathering, erosion, and transportation. Weathering breaks down rocks into smaller pieces, erosion moves these pieces to new locations, and transportation carries them away. Over time, these processes create sediment from the broken down rocks.
What is the backbone of a mountain?
The backbone of a mountain is typically composed of rock layers that have been compressed and uplifted through tectonic forces, forming a prominent ridge or peak. These rocks are often more resistant to erosion compared to surrounding material, which helps maintain the mountain's shape and elevation over time.
Is the process through which rocks or others materials are broken down?
Weathering, erosion.

What is a stack of rocks called that you build when you get to the top of a mountain?
A stack of rocks built at the top of a mountain is called a cairn. They are often used as trail markers or symbols of accomplishment by hikers and mountaineers.
What does a mountain have on it?
a mountain is just dirt and rocks until you pile it 10,000 ft. tall - and call it majestic !!
Why is mountain and water fall water always clean?
Because when the water flows through the rocks, the rocks catch all the dirt.
How are rocks broken down by weathering?
rocks are broken down by weathering when corrosion takes place. this is when sea water is very corrosive and can slowly dissolve chalk and limestone, increasing the size of cracks and joints so that the forces of erosion are more effective.
How do clastic rocks differ from non-clastic rocks in terms of process of formation?
Clastic rocks are composed of broken pieces of older rocks that have been broken up by the process of weathering and are therefore sedimentary in nature. The "clasts" (bits of older rock) may vary in size.
What is scree?
Scree is a collection of broken rock fragments found at the base of cliffs or steep rocky slopes. It is formed through the process of frost weathering, where water seeps into fractures in the rocks, freezes, and expands, causing the rocks to break apart and fall to the base of the slope.
