sedimentary
The inner layers are laid down by earlier eruptions, and are then buried under ash and lava from later eruptions.
what is mountain formed from layers of lava and ash
Assuming the layers aren't deformed, the lowest deposition layers are the earliest. Later deposition layers accumulate on top of the earlier layers. Thus, the lowest layers have the earliest fossils, and the highest layers have newer fossils. By comparing the features of early and late fossils of a species, you can determine some of its evolutionary changes. Of course, not all features survive in a fossil - soft tissues, for example.
Layers at the bottom are the oldest.
It is the Universe that expanded, not specifically the Earth. Earth was formed much later than the Big Bang. The Universe continues expanding, though.It is the Universe that expanded, not specifically the Earth. Earth was formed much later than the Big Bang.

The blastula is an embryonic structure that is formed from one cell layer. This later forms the three cell layered gastrula. All of the layers of the organism are formed from these three layers. See the link below:

Plants which died and decayed and were buried by later material.
They are formed inside nucleolus.Later brought to the cytoplasm.
They are formed at the bottom later of the epidermis.
Gastrula!!!!

use the pause button or the stop button, you can resume it later if you have pressed pause
The crystals formed early by magma would not be deficient of certain elements. Once these elements are used up, they are not available in the magma to form later crystals.
Unless disturbed by later events, younger layers overlie older layers. See the law of super-position.
By little organisms which later formed into fish later in the years such in the Prehistoric Time.
