answer:

a.magma rises into the spaces where tectonic plates pull away from one another

explanation:

seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor. the mid-atlantic ridge, for instance, separates the north american plate from the eurasian plate, and the south american plate from the african plate.

good luck :)

i hope this helps

have a nice day !!

To investigate absorption, Hector cuts two rectangles from five different-colored sheets of construction paper. He then staples three sides of each pair of rectangles to make a pocket and inserts a thermometer into each.

He takes the thermometers in the construction paper pockets outside, where it is clear and sunny. The initial temperature of each thermometer is 22°C. The image shows the thermometers after being outside for 15 minutes.

A thermometer in black paper reads 38 degrees Celsius, a thermometer in white paper reads 24 degrees Celsius, a thermometer in green paper reads 29 degrees Celsius, a thermometer in red paper reads 31 degrees Celsius, and a thermometer in blue paper reads 33 degrees Celsius.
Complete Hector's table by recording the final temperature and calculating the temperature change for each thermometer.
