Question
which process can cause tectonic plates to move

The process that causes tectonic plates to move is called plate tectonics. Plate tectonics is driven by the movement of the mantle layer beneath Earth's lithosphere. This movement is a result of convection currents in the mantle, which transfer heat from the core to the surface. As the mantle material heats up and becomes less dense near the core, it rises towards the surface, while cooler, more dense material sinks back down. This convection motion drags and pushes the overlying tectonic plates, causing them to move in different directions.

The process that primarily causes tectonic plates to move is thermal convection in the mantle. While the other processes you mentioned, such as solar conduction, thermal currents, and ocean currents, can affect surface temperatures and circulation patterns, they do not play a significant role in driving the movement of tectonic plates.
Answer
why are absolute dating and relative dating DIFFERENT?
one uses other rock layers, the other uses radioactivity
One uses cleavage, the other uses luster
they both try to find the date rocks
one uses minerals the other uses rocks

Absolute dating and relative dating are different methods used to determine the age of rocks and fossils.
Relative dating is a method of determining the relative order of past events, without necessarily determining the actual age in years. It relies on the observation of rock layers and the principles of stratigraphy, such as the law of superposition and the principle of cross-cutting relationships. By studying the position and relationships of different rock layers, archaeologists and geologists can establish a relative timeline of events. For example, they can determine that one rock layer is older or younger than another based on their relative positions.
On the other hand, absolute dating is a method of determining the exact age of rocks or fossils in years. It uses various techniques, such as radiometric dating, which involves the decay of radioactive isotopes in minerals within the rocks. By measuring the amount of parent and daughter isotopes in a mineral sample, scientists can calculate the age of the rock. Other forms of absolute dating include dendrochronology (using tree rings) and varve counting (counting annual layers in sedimentary rocks).
In summary, relative dating relies on the observation of rock layers and the principles of stratigraphy, while absolute dating uses various methods, including the decay of radioactive isotopes, to determine the exact age of rocks or fossils.
