How can Earth’s layers be defined? Select the two correct answers.(1 point)

The two correct answers for defining Earth's layers are:

1. by their chemical compositions
2. by their physical properties

Fracture Cleavage

It seems like your request may require direct interaction with a system or application, as you're asking to drag items to categorize them. Unfortunately, I can't interact with external systems or provide a drag-and-drop interface. However, I can help you understand the difference between fracture and cleavage, and you can then categorize your items based on that understanding.

- **Fracture** refers to an irregular break in a mineral where the surface is rough and uneven. An example would be quartz, which often breaks with a conchoidal fracture.

- **Cleavage** refers to the tendency of a mineral to break along flat, even surfaces, which are typically aligned with its crystal structure. An example would be mica, which cleaves easily into thin sheets.

If you have specific minerals or items you'd like to categorize, please list them, and I can help you determine which exhibits fracture or cleavage!

Which evidence would confirm that a given rock layer is newer than the layers around it?(1 point)

Responses

It cuts through all the other layers.
It cuts through all the other layers.

It is horizontally-oriented.
It is horizontally-oriented.

Other layers have been deposited above it.
Other layers have been deposited above it.

It has been crumpled and folded, while the other layers lie flat.

The evidence that would confirm that a given rock layer is newer than the layers around it is:

**It cuts through all the other layers.**

This indicates that the rock layer is younger than the layers it disrupts.
