Question

which best describes the relationship between temperature and pressure in the earths interior? * 5 points
both temperature and pressure increase with depth.
temperature increases with depth, but presure decreases.
temperature decreases with depth, but pressure increases.
both temperature and pressure decrease with depth.

which kind of seismic wave can move through liquid rock? * 5 points
s - wave
p - wave
surface waves
body waves

Explanation:

First Question:

To determine the relationship between temperature and pressure in Earth’s interior, we recall geological principles: as depth increases, the weight of overlying material causes pressure to rise, and the Earth’s internal heat (from radioactive decay, residual heat) means temperature also increases with depth. So the option stating both increase with depth is correct.

Seismic waves: S - waves (shear waves) cannot travel through liquids, while P - waves (primary waves, compressional) can travel through solids, liquids, and gases. Surface waves travel along the surface, and body waves include both P and S waves (but S - waves can’t go through liquid). So P - wave is the one that moves through liquid rock.

Answer:

A. Both temperature and pressure increase with depth.
