Look at the Grand Canyon cross section. What is the 4th event to take place in the Grand Canyon's geologic history? Question 6 options:

The Shinumo Quartzite was deposited in a beach environment.

Dox Sandstone is deposited in a beach environment

Igneous Intrusion.

Deposition of the Bass Limestone in a shallow marine environment

bass limestone

Explanation:

if I'm right bass limestone is the fourth one because 3 are under it

this means that the temperature of both substances will be equal

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
