It's new student orientation! Fine weather yesterday for our hammer-source geophone array demonstration. Every swing of the sledgehammer improves the image of depth-to-bedrock, and potentially even shows the top of the REM tunnel under Mont Royal!

The ground we live on is the top of a moving rock area that is really hot. The ground we live on is broken up into little rocks. Sometimes the little rocks move on top of each other. This makes the rocks get really tall. Sometimes one goes under the other one. The under rock gets really hot and becomes the moving rock under the ground. The moving rock under us sometimes comes up through the ground making new hot rock. [J. G.]

Upon death, living things either break down as the surrounding air, in a way, quickly eats up what is left of them or, they get covered under ground when not broken down. As the ground layer above gets bigger and heavier, the remains are pressed into a different and thicker form of matter. It takes a lot of time for the ground layer to grow heavy enough to change the state of the matter in such a way. Those old remains can then be burnt for power.

The really big ball that we live on is made of huge pieces of ground that move around. Sometimes they knock into each other, run away from each other, or slip side to side. If two of them get stuck, power builds up in the rock and lets go as they are set free. The ground shakes a lot, large cracks form, rocks might slip down, and houses fall. If that happens in the big water area, a very tall wave will move onto the land and run into it. [M. T.]

Another group of #EarthSystemScience #UpGoer5 Change that happens quickly and continues to grow. The growing that happens begins to happen faster and faster than it did at the start. The number of people in the world is a good way to understand this. It grows faster and faster than it did before. [K. A.]
#ExponentialGrowth #McGillUniversity

#UpGoer5 As the number of people gets bigger in an area, the number of stuff that is able to back them up gets lower. The number of people found in a place, is controlled by what is going on around them; such as how much food, water and homes is found. But when the total of how much of these is found around them gets lower, the total number of people coming into this world gets less. They then reach a still state where the number of people
stops getting big. #CarryingCapacity #McGillUniversity

Trees can tell us is what the world was like in the past. The rings inside a tree can show us how much it grew each year. In wet years, the tree will grow a thick ring, and in dry years, it will grow a small ring. People can study tree rings to see how hot and cold the world has been and how it has changed over time. This is important because it helps us understand how the world is changing now and how it may change.

Ekman spiral continued....
The deeper water does not feel the wind, but it does feel the water above moving. So the same thing happens again, except this time the water goes in a direction even further from that of the wind, and so on, turning as we go deeper. At each step, we lose a bit of force, so we have less and less as we go down.

When there is wind over water, the water's direction is normal to that of the wind. Whether it goes left or right is decided by the side of the mother ball we are on. Since the mother ball turns, the water closest to the middle goes the fastest. So when wind carries water further away from the middle, the water keeps its force, and that's why it doesn't move in the same direction as the wind. Continued....
