What are some effects of gravity we can experience on Earth?
A. Tides
B. Seeing the position and phase of the Moon each day
C. Earth orbiting around the Sun
D. Earth’s atmosphere keeps us aliv

A and C

Explanation:

Earth has a gravitational pull towards the sun keeping in orbit and the moon have a gravitational pull on the water on earth

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 .. .

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
