Each fossil with the layer where it will be present based on are layer A-BIRDS, layer B -dinosaurs , layer C-amphibians, layer D-Corals ,layer E -trilobites.
<h3>What is the oldest fossil layer?</h3>
The Pilbara area of western Australia's Strelley Pool is home to the oldest known fossils. Stromatolites are fossilized mats of microorganisms wedged between sedimentary layers. The fossils have an age of 3.4 billion years.
<h3>How are the layers containing the fossils organized?</h3>
The Law of Superposition, which asserts that in undisturbed rock sequences, the bottom layers are earlier than the top ones, is the foundation for this theory. Because of this, certain fossil discoveries can be dated using the strata—a particular stratum of rock—in which they were discovered.

It makes the Earth livable for us creatures. We get protected from the Sun's harmful rays reaching to Earth, which makes Earth feel comfortable. Atmosphere also contains Oxygen and we rely on that everyday.
Answer:
The answers that apply;
Researchers found cosmic microwave background radiation, which is a heat imprint left over from the big bang.
A redshift of light emitted by stars and galaxies indicates the universe is expanding
A primordial form of helium gas was found by the Endeavor space shuttle
Big Bang theory is a theory that endeavors to explain the origin of the universe. It stipulates that the universe exploded from a singularity and continues to expand today

Answer:
Answer 1:
Seismic waves, the waves of energy that travel through the Earth as a result of an earthquake can tell us a lot about the internal structure of the Earth because these waves travel at different speeds in different materials. There are two types of waves that travel through the Earth: p-waves and s-waves.
P- waves are faster and they can travel through both solids and liquids. S-waves are slower and cannot travel through liquids. For both kinds of waves, the speed at which the wave travels also depends on the properties of the material through which it is traveling.
Scientists are able to learn about Earth’s internal structure by measuring the arrival of seismic waves at stations around the world. For example, we know that Earth’s outer core is liquid because s-waves are not able to pass through it; when an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive. Similarly, we know that the earth has a solid inner core because some p-waves are reflected off the boundary between the inner core and the outer core. By measuring the time it takes for seismic waves to travel along many different paths through the earth, we can figure out the velocity structure of the earth. Abrupt changes in velocity with depth correspond to boundaries between different layers of the Earth composed of different materials.
Explanation:
<span> water has a tendency to move across a membrane from a lower osmolarity to a higher osmolarity.
</span>
<span>When red blood cells are placed in distilled water, which is hypotonic compared to the solution contained within the cells' membranes, the distilled water will diffuse into the red blood cells and cause them to burst.</span>
