Sedimentary rocks are most likely to form from the weathering and erosion of pre-existing rocks. As these rocks break down into smaller particles, they can be transported by wind, water, or ice and eventually accumulate in layers. Over time, these sediments are compacted and cemented together, leading to the formation of sedimentary rock types such as sandstone, limestone, and shale.

What type of rocks weather and erode to form sedimentary rocks?
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
Why do you think weather is used to refer to the breakdown of rocks?
Weathering is the process of breaking down rocks into smaller pieces through physical or chemical means. This term is used because the rocks are gradually "worn down" by the elements of weather, such as rain, wind, and temperature changes. Over time, these weathering forces can cause rocks to crumble and erode.
Why do large round rocks erode faster than rocks with sharp corners?
Its actually more about the composition of the rock than the shape, the rounded rocks tend to be of a softer material such as sandstone, limestone etc which erode quicker and as such form into rounded shapes were harder rocks such as granite are more resistant to erosion and therefore its the softer materials that erode and leave the sharp edges of granite.
What process will most likely chemical weather on iron-rich rocks?
The most likely process that will chemically weather iron-rich rocks is oxidation. When iron is exposed to oxygen and water, it can react to form iron oxide, commonly known as rust. This process weakens the rock structure and can eventually lead to the breakdown of the rock into smaller fragments.
How do the rocks fit in the rock cycle?
Rocks are constantly being formed, broken down, and reformed in a process known as the rock cycle. Igneous rocks are formed from cooled magma or lava, which can then weather and erode to form sedimentary rocks. These sedimentary rocks can undergo heat and pressure to become metamorphic rocks, which can in turn melt and cool to form igneous rocks again, completing the cycle.

Why sedimentary rocks could not have been the first rocks on earth?
Sedimentary rocks form from the accumulation of sediment such as sand, silt, or clay. For sedimentary rocks to form, there must be pre-existing rocks that weather and erode to produce sediment. Therefore, sedimentary rocks could not have been the first rocks on Earth as they require the presence of older rocks to form.
How do igneous rocks form into metamorphic and sedimentary rocks?
Igneous rocks can form metamorphic rocks by being subjected to high heat and pressure, causing recrystallization of minerals. Igneous rocks can also weather and erode to form sediment, which can then be deposited, compacted, and cemented to form sedimentary rocks.
What property of water allows it to form sinkholes?
It's ability to weather and erode rock.

As rocks erode from Earth's surface the process they are replaced by is?
The process by which rocks are replaced as they erode from Earth's surface is called deposition. Deposition occurs when eroded rocks and sediments are transported to a new location and settle out of the transporting medium, such as wind or water, to form new layers of sedimentary rock.
What type of mountains are the adirondack mountains?
These are upwarped mountains. They form when blocks of Earth's crust are pushed up by forces within Earth. Over time, the soil and sedimentary rocks at the top of Earth's crust erode, exposing the hard, crystalline rock underneath. As these rocks erode, they form the peaks and ridges.

How can igneous sedimentary and metamorphic rocks form?
igneous rocks form when hot molten rock cools and solidifiessedimentary rocks form when other rocks erode and the erosion products collect then are buried and fuse together or minerals are deposited by living things and are buriedmetamorphic rocks form when other rocks are buried deep and the high temperature and pressure removes volatiles and modifies crystal structures in the rock
According to the rock cycle what transitions are possible assume an unlimited number of steps?
In the rock cycle, rocks can transition between three main types: igneous, sedimentary, and metamorphic. For example, igneous rocks can weather and erode to form sediment, which can then compact and cement into sedimentary rocks. Sedimentary rocks can be subjected to heat and pressure, transforming them into metamorphic rocks. Conversely, metamorphic rocks can melt into magma, which can cool and solidify into igneous rocks, creating a continuous cycle.
