Because the sediments will accumulate in the sides.
Imagine a ball, start covering it with paper, later with aluminum foil, the old part (the ball) will be in the bottom, the not so old part (the paper) will be in middle and the newest part (the aluminum foil) will be outside.
Hope you understand.

What part of the sedimentary of rock is the oldest?
Protolith is a term used to describe the parent rock of a metamorphic rock. Conglomerate is a sedimentary rock that can be composed of clasts of sedimentary, igneous, or metamorphic rocks, or any number of combinations of all.
What is the oldest sedimentary rock?
In an undisturbed strata, the oldest layers are at the bottom. It's called the law or principle of superposition.
In layers of undisturbed sedimentary rock the oldest rocks are on the?
Factors such as wind, ice, and warder contribute to sedimentary build up. As this occurs older layers of sedimentary rock are driven lower while newer layers replace them closer to the surface.
Which rock layer is the oldest and why?
The oldest rock layer is typically found at the bottom of a sequence of sedimentary layers, following the principle of superposition in geology. This principle states that in an undisturbed sequence of rock layers, the oldest layer will be at the bottom and the youngest at the top. Therefore, the rock layer closest to the Earth's surface is usually the youngest, while the rock layer at the bottom is the oldest.
Is The top layer of sedimentary rock is the oldest true or fasle?
True. In an undisturbed sequence of sedimentary rocks, the bottom layer is the oldest and the top layer is the youngest due to the principle of superposition, which states that in any undisturbed sequence of rock layers, the youngest rocks are at the top and the oldest are at the bottom.
Where can you find the oldest fossils in sedimentary rock layers?
The oldest fossils are typically found in the deepest sedimentary rock layers, which are located at the bottom of a rock formation. This principle is known as the law of superposition in geology, where older rock layers are found beneath younger ones.
Is the layer of rock at the bottom of a sedimentatry rock younger or older?
The layer of rock at the bottom of a sedimentary rock is older. This is due to the principle of superposition, which states that in an undisturbed sequence of rock layers, the oldest rocks are at the bottom and the youngest are at the top.
Where are the oldest layers of a sandstone rock located?
Sandstone is a sedimentary rock. Sedimentary rocks form from sediments that deposited by the wind and water. Over the time those sediments will get pressed and cemented together. It can take millions of years for sediments to become a rock. So the oldest layers of a sandstone are on a bottom.
Would the oldest sedimentary rocks be at the top or the bottom of the cliff?
bottom
In rock layers what is usually found at the bottom?
In rock layers, the oldest rocks are typically found at the bottom. This is due to the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are deposited first and are at the bottom, while the youngest rocks are at the top.
Where will the oldest sedimentary rock be?

What is a Rock formed particles that have fallen to the bottom of a lake or ocean?
The rock type thus formed would be sedimentary. What type of sedimentary rock formed would depend on a multitude of factors.
