Can you determine the age of something like a fossil by examining its half life?
GeologyAlso called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the organism that was preserved. This technique relies on the property of half-life. How is half-life used to determine age? To determine the absolute age of this mineral sample, we
What happens on a convergent plate boundary?
GeologyA convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events. What happens at a convergent boundary?

What forces are involved in a tsunami?
GeologyTsunami are waves caused by sudden movement of the ocean surface due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean. What are the forces of a tsunami? Tsunami waves have a dynamic force, corresponding to horizontal motion, and a hydrostatic force related
