The stack of rocks and the order of the rock layers represents the history of sea-level changes.
Sandstone, shale, and limestone are sedimentary rocks that were formed from the accumulation of sediment at the bottom of the ocean or a large lake. As sea level changes, the type of sediment that is deposited on the ocean floor changes as well. Sandstone is typically formed in shallow waters, near the shoreline. As sea level rises, the shoreline moves inland, and the deposition of sandstone is replaced by shale. Shale is formed in deeper waters, where there is less sediment and the water is calmer.
When sea level drops again, the deposition of shale is replaced by limestone. Limestone is formed in clear, shallow waters, where there is a lot of sunlight for the growth of coral and other marine life. The layers of rock in the stack can indicate that there have been multiple cycles of sea-level changes over time, with each layer representing a different period of time when the ocean was at a different level.

in the discussion of earth's annual energy balance, we saw that earth absorbed approximately 51 units of solar energy but emitted 117 units of infrared energy. what prevents earth from getting colder and colder?
In the discussion of the Earth's annual energy balance, it has been seen that the Earth absorbed about 51 units of solar energy but emitted 117 units of infrared energy. The Earth is prevented from getting colder and colder by the greenhouse effect.
The greenhouse effect is a process that takes place in the Earth's atmosphere in which greenhouse gases (carbon dioxide, methane, and water vapor) trap some of the outgoing energy from the Earth's surface, thereby warming the planet's lower atmosphere and the surface. The energy is trapped because of the greenhouse gases, which act like a blanket, keeping the planet warm. If the greenhouse gases were not present in the Earth's atmosphere, most of the infrared radiation would be lost into space, resulting in a much colder planet.
The Earth's annual energy balance refers to the balance between incoming solar radiation and outgoing infrared radiation. The Earth's energy balance is a dynamic process in which energy is constantly being absorbed and emitted, but over the long term, the incoming energy and outgoing energy are balanced.Therefore, the greenhouse effect is the process that prevents the Earth from getting colder and colder despite emitting more energy than it absorbs.

Marine geologists know that potassium-40 decays to argon-40 with a half-life of 1.3 billion years. An analysis of a feldspar crystal in a sample of granite shows that 75% of the potassium-40 atoms have decayed to form argon-40. The age of the granite is 2.6 billion years.
To calculate the age of granite, we will use the half-life equation, which is as follows:
N = No(e^(-λt)) Where, N = The number of atoms remaining.
No = The number of atoms that were initially present. λ = The decay constant.t = Time elapsed since the formation of the rock.e = The base of the natural logarithm. In the given question, the half-life of Potassium-40 is 1.3 billion years. Therefore, we can calculate the decay constant as follows:λ = 0.693/t½= 0.693/1.3 x 10^9= 5.33 x 10^-10 year^-1Now, let's use the half-life equation to find out the age of granite:0.25No = No(e^(-λt))0.25 = e^(-λt)
Taking natural logarithms on both sides, we get:-ln 0.25 = -λtln 2.718 = 5.33 x 10^-10 t

We would need to weather and erode the metamorphic and igneous rocks to produce sediment, then lithify the sediment through compaction and cementation processes.
The accumulation and lithification of sediment results in the formation of sedimentary rocks. Igneous and metamorphic rocks are created via separate processes, and they often do not produce sediment. We would therefore need to weather and erode these kinds of rocks in order to produce sediment before we could turn them into sedimentary rocks. This could entail chemical and physical weathering procedures such oxidation, water erosion, and freeze-thaw cycles. Once the rocks have been reduced to silt, they would need to be moved and dumped in an appropriate location for lithification to take place.

layers. They can then organize these rock layers based
on their age from oldest to youngest on the geologic
time scale. Based on this organization, they can tell
which organisms lived and what was happening to
Earth at that time
Scientists use relative and absolute dating methods to determine the age of rocks and fossils and to organize Earth's 4.6-billion-year-old history.
Relative dating involves placing rocks and fossils in chronological order based on their positions in layers of sedimentary rock. The principle of superposition, for example, states that in an undisturbed sequence of sedimentary rocks, the oldest layer is at the bottom and the youngest layer is at the top. Absolute dating involves using radioactive isotopes to determine the exact age of rocks and fossils. This is done by measuring the decay of isotopes over time. For example, carbon-14 dating is used to determine the age of organic materials up to 50,000 years old, while uranium-lead dating can be used to determine the age of rocks that are billions of years old. Using these dating methods, scientists have developed the geologic time scale, which is a timeline of Earth's history based on major events and changes in the rock record.
