Cirrus cloud can predict fair-pleasant weather.
The rate of chemical weathering is controlled by such things as the temperature, the amount of rainfall and the surface area of the minerals which constitute the rocks. Rocks with a finer grain size have more surface area than coarse-grained rocks so are more susceptible to chemical weathering, like a volcanic rock compared to a granite, say. With higher temperatures and greater rainfall, chemical reactions in the rocks are facilitated and this is why, for example argillic (clay alteration) alteration is so well developed in the tropics (in El Salvador for example and also why the lateritic soils develop in countries like Indonesia and can contain economic amounts of nickel for exampl) . A factor which controls the rate of physical weathering could be the development of glaciers which transport rocks in their bed, which shapes these boulders and also scores the rocky surfaces these scrape over as the glacier moves. Alternate freezing and thawing in the spring time in the northern hemisphere can speed up the breakdown of the rock by cracking it or opening up pre-existing joints and faults.
and also the surface area of the minerals being attacked.
Oil is what those countries rely on the most
Answer:
D. after 3 minutes, Sam is 40 meters from the dock.
Explanation:
For an input of 3, the function will produce a value of 40. That is in 3 minutes, the boat would have covered a distance of 40meters.
We can solve this problem using the given graph.
We know that this is a distance - time graph. The slope of this graph gives the value of the speed of the boat.
- From the time - axis, mark point 3 which corresponds to the input given.
- Trace it up to the point where it coincides with the graph.
- Then find the distance axis value of the point.
- Doing this yield 40m
So, in 3 minutes, Sam will row a distance of 40m.
