atosphere
The oldest layers of sediments are typically found at the bottom of a sedimentary rock sequence, with the youngest layers at the top. Over time, new layers of sediments accumulate on top of older layers, creating a chronological sequence with the oldest layers at the bottom.
The three main parts of Earth's atmosphere are the troposphere (closest to the surface where weather occurs), the stratosphere (contains the ozone layer that absorbs UV radiation), and the mesosphere (where meteors burn up).
Geologists know that rock layers are undisturbed by examining the relationships between the different layers. If the layers are parallel and show no signs of folding, tilting, or faulting, they are likely undisturbed. Additionally, the presence of index fossils can help date the layers and determine if they have been disturbed.
Rock layers that are arched upward typically form anticlines. Anticlines are characterized by an upward curve or fold in rock layers where the oldest layers are found in the center of the fold and the youngest layers are found on the outer edges.
Soil layers that can be penetrated by water are typically the topsoil and subsoil layers. These layers are important for water infiltration, root penetration, and nutrient cycling. The ability of water to penetrate these layers is crucial for plant growth and ecosystem functioning.

The athmosphere
The Earths athmosphere is one of the most important things to us. The athmosphere is very delicate and contains all the protection we need from meteorites, UV rays, and allows the Earth to sustain life.
Solar energy provides heat. It makes the atmosphere warm.
Nitrogen is the highest concentration, it makes up 78% of the atmosphere by volume.
Earth's atmosphere is composed of (approximately) 79% Nitrogen, 20% Oxygen and 1% 'other' gasses (such as Argon, Carbon Dioxide etc).
Modern Diesel cars often have a diesel particle filter (DPF) installed in the exhaust to trap fine soot particles and stop them getting into the athmosphere.
Based on the graph, can you generalize that the higher the layer of the atmosphere (that is closer to the sun), the hotter the temperature? Why or why not
The terminology of space debris entering the Earth's athmosphere is a question of timing. Outside the athmosphere, the debris is considered a 'meteoroid.' Upon entering the athmosphere and while falling to the Earth, the debris is called a 'meteor.' After striking the Earth, whatever material did not disintegrate is called a 'meteorite.' So when you see a 'shooting star,' it is not a meteorite. It is technically a 'meteor.' Only after you find it on the ground is it a 'meteorite.'
Due to large-scale burning of fossil fuels worldwide, the concentration of carbon dioxide in the athmosphere continues to increase. This enhances the natural 'greenhouse effect' of the athmosphere, causing global warming and climate change.
