Describe the role gravity plays in the phases of the moon. A
The moon’s gravitational pull changes the position of the Earth relative to the moon and sun. This causes the phases of the moon.
B
The sun’s gravitational pull on the moon causes changes in its position relative to the Earth. This causes the phases of the moon.
C
Gravity causes the Earth to spin; this causes the Earth to change position relative to the moon. This causes the phases of the moon.
D
Gravity holds the moon in orbit around the Earth; each month as it orbits the Earth, the moon changes in position relative to the sun and the Earth. This causes the phases of the moon.
please i need help

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .

explanation:

the sun shines white and black light to our planet. the white light has all the colors in it. in our upper atmosphere, we have dust particles and oxygen molecules. the white light meaning all of the colors in a rainbow shines through the upper levels of the atmopshere and the blue light scatters across the entire planet. that is why our sky is blue.
