A group of students are designing a roller coaster to investigate energy transformation from one form to another Materials About 2 foam tubes cut into half, paper cups, wood, glass and metal marbles, plastic boxes, masking tape,
Step 1. Cut the foam tubes lengthwise into half.
Step 2 - Stack two paper cups one on top of the other above the plastic boxes.
Step 3 - Attach one end of the foam tubes on the paper cups using a masking tape.
Step 4 - Twist the foam tube and stick it at the other end to the floor with masking tape in order to design a roller coaster
Step 5 - Place one paper cup horizontally aligned to the end of the foam tube secured on the floor with the masking tape.
At which position will the marble have the LEAST Potential energy?

the answer would be..

b. sucking

wegner's theory did not explain how the continents could move

explanation:

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.

paper covers rock.

explanation:

rock only smashes scissors.
