How can scientists use data from an earthquake to learn about Earth's layers? Hint for this question is A seismograph is an inst
rument used to measure a seismic waves during an earthquake. Question 2 - Describe at least two geological events that can occur at a divergent boundary.
"Scientists can tell by observing the seismic waves that are recorded all over the surface of the earth from distant earthquakes. The seismic waves are reflected (bounced off) layers of different density, and they are refracted (bent) when they enter layers of different density."
Scientists learn about the layers deep within the Earth's crust by studying how seismic waves travel ... Usually, they use seismic waves, which are waves generated by earthquakes

NOT REALLY REQUIRED BUT YOU CAN USE JUST FOR YOUR REFERENCE..
Excellent question! Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers. Different types of materials (liquid vs. solid, rigid vs. softer) determine the speed of the waves. Bending of the waves occurs at the layer's boundaries. So, scientists study the path and speed of these waves through the earth to decipher boundaries and the materials that make up the layers.
THATS WITH QUESTION 1 Now 2
Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
Plants extract CO2 from the air and also use sunlight and water as the reactants of the process photosynthesis. Photosynthesis then produces Glucose and Oxygen. Oxygen is rid of the plant.
