Unit 2 Earth Science

Front

What is the independent variable in the hypothesis: 'The more grams of salt a person eats, the higher their blood pressure'?

Back

Grams of salt a person eats.

Front

Define Convergent Boundary (Continent-Continent).

Back

When two continental plates collide, they create mountain ranges because the plates are the same density.

Front

Which types of seismic waves can travel through both liquids and solids?

Back

P waves.

Front

What is the asthenosphere?

Back

The semi-fluid layer of the Earth's mantle beneath the lithosphere and above the mesosphere.

Front

What technological advances contributed to the acceptance of Wegener's hypothesis of continental drift?

Back

Advancements in seafloor mapping, radiometric dating techniques, and magnetometers.

Front

What is the lithosphere?

Back

The rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

Explain the difference between P waves and S waves.

Back

P waves are primary waves that can travel through both liquids and solids, while S waves are secondary waves that can only travel through solids.

Front

What is the significance of the mid-ocean ridge in plate tectonics?

Back

It is a divergent boundary where new oceanic crust is formed as tectonic plates move apart.

Front

Define the term 'plate tectonics'.

Back

The theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What is a transform boundary?

Back

A boundary where two tectonic plates slide past each other horizontally.
