What is relative dating in geology?

Back

Relative dating is a method used to determine the age of rocks and fossils by comparing their placement in layers of rock, with the oldest layers at the bottom and the youngest at the top.

Front

What type of rock is most likely to contain fossils?

Back

Sedimentary rock is the type of rock where fossils are usually found.

Front

What is an example of biotic weathering?

Back

Tree seedlings growing and forming cracks in rocks is an example of biotic weathering.

Front

What theory explains the movement of continents?

Back

The theory of continental drift explains how continents move on tectonic plates.

Front

What causes rock layers to move?

Back

Plate tectonics is the primary cause of movement in rock layers.

Front

What is the Law of Superposition?

Back

The Law of Superposition states that in undisturbed rock layers, the oldest rocks are at the bottom and the youngest are at the top.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How do scientists determine the exact age of rock samples?

Back

Scientists use radioactive isotopes to determine the exact age of rock samples.

Front

What is the role of deep sea currents in geology?

Back

Deep sea currents can influence the movement of tectonic plates and the formation of geological features.

Front

What is a mudslide?

Back

A mudslide is a rapid flow of mud down a slope, often caused by heavy rain or earthquakes.
