Would the oldest rocks on earth be igneous or sedimentary?
The creation of igneous rock from magma is dependent on the cooling rate of the magma. Some igneous rocks form almost instantaneously, and others take hundreds of thousands of years. So igneous rock could be the youngest of the three rock types at any given point in time.
Is chert metamorphic sedimentary or igneous?
Brick is baked mud, and as such, can be considered to be sedimentary.
What describes rock that was formed when molten rock cooled down?

Is a river rock a sedimantary rock a igneous rock or a metamorphic rock?
A river rock can be any type of rock, including sedimentary, igneous, or metamorphic. It depends on the geology of the area where the river rock was sourced from and subsequently deposited.
If a metamorphic rock contains and intrusion of igneous rock which rock is the oldest?
In this scenario, the igneous rock intrusion is the youngest rock, as it formed after the metamorphic rock was already in existence. The metamorphic rock must have been present before the igneous rock intruded into it, making the metamorphic rock the oldest of the two. Thus, the metamorphic rock is the oldest in this context.
How does sedimantary rock change into metamorphic rock?
When the sedimentary rock gets pressed with great pressure, it'll turn to metamorphic rock. Also, heating of the sedimentary rock by igneous intrusions will metamorphose it.
Is chalk a sedimantary rock?

Why is north wales an upland area?
