Greater velocity / Lesser time
Greater Velocity = greater acceleration
Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which
states both variables are positively correlation. It is when both the
variables increase or decrease together. On the contrary, indirect variation or proportion indicates
negative relationship or correlation. Elaborately, the opposite of what
happens to direct variation. One increases with the other variables,
you got it, decreases. This correlations are important to consider
because you can determine and identify how two variables relates with
one another. Notice x = y (direct), y=1/x (indirect)</span>
1. Divergent Plate Boundaries or Constructive Plate Boundaries. This is where two plates separate. Ridges are created when mantle convection rises up beneath it, with extreme heat, the crust will thin, and the igneous material beneath will eventually.
<span>2. Divergent, or destructive plate margins cause volcanoes. As the more dense plate subducts, it will melt at depth and the water driven off, will lower the melting point of the overlying mantle wedge, this will create a type of magma. Volcanic Island Arcs are formed at oceanic-oceanic destructive plate margins. The hot, bouyant magma, is less dense that the surrounding rock, so will rise to the surface, and will collect beneath the plate that hasn't been subducted. It will then, under increased pressure erupt under the sea. Over thousands to millions of years, it will keep erupting, to form islands. </span>
<span>3. Earthquakes are mainly caused at Transform boundaries and Divergent boundaries. At transform boundaries, two plates sliding past eachother, and the build up of friction could lead to earthquakes, if enough stress is built up and then suddenly released, then the energy is released as seismic waves or an earthquake. At divergent boundaries, earthquakes happen along the Benioff zone which is the slope of the subducting plate that is slowly being dragged into the mantle by mantle convection and slab pull. </span>
<span>4. Divergent boundaries cause orogenisis (mountain building). But only the continental-continental margin where two continental plates are colliding. Because they are the same density, they don't subduct, but they buckle, compress and uplift to form mountains. Just like the himilayas, when the Indian plate collided with the eurasian plate.</span>
Answer:
Explanation:
Given that:
The abundance of three algal species in Lake A is now represented by the vectors:
[97, 84, 43] and [100, 80, 50]
Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:
a = [100 -97, 80 - 84. 50 - 43]
a = [3, -4, 7]
Thus, the magnitude of that change is:
The abundance of three algal species in Lake B is now represented by the vectors:
[25, 59, 22] and [20, 63, 15]
At Lake B, the change occurring in the vector of algae species can be determined as:
b = [20 -23, 63 - 59. 15 - 22]
b = [-3, -4, -7]
Thus, the magnitude of that change is:
Hence, for both Lake A and B, the magnitude of change is the same.
Answer:
Q.1: I can't help you with this, sorry :(
Q.2: Seaweed is the producer because it takes energy from the water and sun in thermal reactions.
Q.3: Phytoplankton is the second-order consumer because they eat first-order consumers.
Q.4: Whelks and crabs because they eat limpets, which eat producers, and they also eat seaweed.
Q.5: Gulls are carnivores because they eat the crabs, and so are crabs because they eat mullets
Q.6: Limpets and lobster would become less populated, but not yet endangered. Gulls would starve and probably disappear from this ecosystem.
Q.7: Whelks' numbers would decrease because of the number of lobsters consuming them, but then lobsters would starve because of the decline in their food. Then this would repeat, shaking the whole ecosystem.
