An intrusion crosses and extrusion. The extrusion is the oldest layer and an intrusion is always younger. 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.
Absolute dating is the process of determining an age on a chronological or specified time scale in which events occurred in archaeology and geology.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.
The carbon-14 isotope is used in radiocarbon dating, but is only useful for measuring recently formed rocks in the geologic past. 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.
Therefore, An intrusion crosses and extrusion. The extrusion is the oldest layer and an intrusion is always younger. 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.

Answer: Therefore, the correct answer is: Waves are seen to approach the beach at an angle.
Explanation:
An observation in science refers to a direct and factual statement based on the information gathered through the senses or measurements. Among the given options, the following statement would be considered an observation:
"Waves are seen to approach the beach at an angle."
This statement describes something that can be directly perceived or measured by observing the behavior of waves as they move towards the beach. It is a factual and observable phenomenon that can be witnessed and documented.
On the other hand, the remaining options involve explanations or concepts rather than direct observations. They provide information about the causes, effects, or mechanisms behind waves, but they do not describe something that can be directly observed or measured. These options involve interpretations, explanations, or generalizations based on scientific knowledge, rather than direct sensory or measurable data.
