Earth Science 2nd Qtr. BATs

Front

What is the ultimate cause of plate tectonics?

Back

Mantle convection is the ultimate cause of plate tectonics, driven by heat from the Earth's interior.

Front

What is the process in which dissolved minerals crystallize and glue sediment together?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together.

Front

What type of sedimentary rock is made of large bits of gravel cemented together?

Back

Clastic sedimentary rock is made of large bits of gravel cemented together.

Front

What evidence supports the theory of Continental Drift?

Back

Fossils, continent shape, and landforms are supporting evidence for the theory of Continental Drift.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often resulting in seafloor spreading.

Front

What is the definition of sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What is the difference between clastic and chemical sedimentary rocks?

Back

Clastic sedimentary rocks are formed from fragments of other rocks, while chemical sedimentary rocks form from the precipitation of minerals from solution.

Front

What is the role of plate tectonics in earthquakes?

Back

Plate tectonics can cause earthquakes when stress builds up at plate boundaries and is released.

Front

What is the significance of fossils in understanding Earth's history?

Back

Fossils provide evidence of past life and help scientists understand the evolution of species and changes in environments.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.
