Question

which of the following best describes a change one would observe in moving from earths crust downward to the outer core? density would change from least to most dense. pressure would change from very high to none. plasticity would change from flexible to rigid. heat would change from relatively hot to cool.

Explanation:

As we move from Earth's crust downward to the outer core, the density increases. The crust is the least dense layer, while the outer core is more dense. Pressure increases with depth, so it would not change from very high to none. Plasticity - the outer core is liquid (more flexible in a sense compared to the rigid crust in terms of movement of material in a liquid state vs solid crust). Heat increases with depth, not decreases.

Answer:

Density would change from least to most dense.
