A rather simplified answer: Weathered rocks are broken down by ice, rain and wind, into smaller rocks, pebbles, sand, and silt. When the lighter sand and silt is carried by rivers, etc. and reaches the sea, it may form a layer on the sea bed. If the layer is placed under tremendous pressure, and is mainly of sand, sandstone is formed (over many eons). If mainly silt, slate is formed.

What type of rock forms from layering of eroded rock?
sedimentary
What type of rocks can be affected by weathering and erosion?
Any type of rock that is at or near the surface could be affected by weathering and erosion. Mountains are eventually flattened; caves are formed underground. Both are the result of weathering and erosion.
What type of weathering that does not change the mineral composition of a rock?
Chemical Weathering
How is tafoni formed?
Tafoni, also called 'honeycomb weathering' are a group of significant pits formed in the surface of a rock. Very common in coastal areas, where the regular wet-dry cycles are obvious. Caused by differential weathering of the rock, and the 'lands' between the pits are often quite thin and lacy in appearance. The presence of salt is thought to be an important feature of this type of weathering.
Which type of weathering occurs when only the size of a rock is changed?
Physical weathering
Which family of rock is formed from weathering?
Clastic sedimentary rock is the usual type of rock formed from the products of rock weathering.
What type of rock could be formed from the weathering and erosion of metamorphic rock?
A Igneous B Sedimentary
What type of sedimentary rocks forms from weathering particles of rocks and minerals?
Sandstone is the sedimentary rock formed from weathered rock.
What type of rock forms from layering of eroded rock?
sedimentary
What type of rocks can be affected by weathering and erosion?
Any type of rock that is at or near the surface could be affected by weathering and erosion. Mountains are eventually flattened; caves are formed underground. Both are the result of weathering and erosion.
Once the rock is formed will it always be an igneous rock?
It is possible, but not likely. It is more likely to undergo metamorphism, or be subjected to weathering and erosion, and end up as a different type of rock.
Conglomerates form from what kind of rock?
Conglomerates form from clastic sediments which are products of weathering, so, conglomeratic materials could be formed from any other rock type. Conglomerate itself is an Example of Mechanically formed Sedimentary Rock.
What type of weathering that does not change the mineral composition of a rock?
Chemical Weathering
What is weathering that does not alter the chemical composition of the rock called?
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.

The type of Weathering in which rock is Physically broken into smaller pieces?
mechanical weathering
What is a type of weathering that changes rock into one or more substances?
Chemical weathering
