The diagram shows the movement of magma due to convection currents. An illustration of the inner core, the outer core and the crust of the earth. Between the outer core and the crust is labeled mantle. In the mantle is sets of arrows in the clockwise direction. In the crust are arrows going both right and left from the center. The crust then is curling into the mantle. Based on the diagram, which part of Earth is the coolest? the crust the mantle the outer core the inner core

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
