I need the answer ASAP pleassse help me 1 Compare and contrast the behavior of the food coloring and the floating pieces of paper before and after adding heat to the system. What caused the changes you observed ?

2 What part of the process of plate tectonics do the water currents represent ? What part of the process of plate tectonics do the pieces of paper represent ? What was the driving force that caused the pieces of paper to move along the water's surface ?

3 Recall your drawings for the different types of plate boundaries . What type of boundary creates earthquakes ? What type of boundaries create volcanoes Compare and contrast these two types of plate movements , and explain how these geologic events occur

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
