How would a geologist use absolute dating to determine the age of sedimentary layers? by dating the age of intrusions and extrusions near a sedimentary rock layer by comparing the relative ages of several sedimentary rock layers by identifying fossils in nearby intrusion and extrusions and determining their age
Answer:
Radiometric dating methods
Explanation:
Absolute dating is the process of determining an age on a chronological or specified time scale in which events occurred in archaeology and geology. Absolute dating can be determined by using properties of the atoms that make up materials.
The most common method of absolute dating uses by geologists is radiometric dating methods which is based on the natural radioactive decay of certain elements such as potassium and carbon found in the rocks. By comparing the ratio of parent isotope with a known half-life to daughter product in the rock, the age of the rock can be determined.
The carbon-14 isotope is used in radiocarbon dating, but is only useful for measuring recently formed rocks in the geologic past. The decay of Potassium-40 isotope known as potassium-argon (K-Ar) method allows dating of materials that up to 1,000 billion years old.

Limestone is in form of sedimentary rock that is made up of skeletal fragments of marine organisms such as forams, corals and molluscs. However, limestone is formed from the shell of an organisms because the shell is made up of calcite or aragonite.
Due to the presence of nutrients that swipe from ocean to the shores along with tides which makes predators to be present along the shores which ultimately pose a threat to coastal aquatic organisms.

in which direction do particles in a solution move during passive transport
During the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending. The passive transport is seen in the cell too.
What is the importance of the different types of transportation?In the cell, different types of transport are seen, such as active transport and passive transport; in active transport, energy is used, while energy is not used in passive transport. The movement of molecules across the cell plasma membrane is important because it allows cells to get rid of unwanted molecules. Passive transport does not require energy, and many nonpolar small molecules and gases can cross the lipid plasma membrane barrier and go into and out of the cell while, in this passive transport process, they save the cell's energy.
Hence, during the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending.
