Rotational slumping is a form of mass movement and occurs on coasts mainly. It involves a large area of land moving down a slope (obviously). Due to the nature of the slip, it leaves behind a curved surface. It’s very common on clay cliffs, during dry weather the clay contacts and cracks. When it rains, the water falls into the cracks and is absorbed until the rock is saturated. It weakens the rock and die to gravity, it slips down the slope on its slip plane.
Answer:
i. 3/5
ii. 2/5
Explanation:
Solving the problem by any of the students A, B and C is an independent event as solution by one does not restrict the other one from solving
However, the problem will be solved if even one of them solves the question
Now Probability of not solving the question by A, B and C are
PA (not solving a problem) - 1-1/3 = 2/3
PB (not solving a problem) - 1-1/4 = 3/4
PC (not solving a problem) - 1-1/5 = 4/5
ii) Probability of not solving - 2/3*3/4*4/5 = 2 *1/5 = 2/5
i) Probability of solving - 1- Probability of not solving
= 1 - 2/5 = 3/5
Answer:
a. Its consideration of environment impact (such as accommodation for fish) became a model for future dam projects on western rivers
Explanation:
The Columbia River project was a project of great significance for the whole region, especially for the state of Washington. This project had many positive impacts such as production of electricity, irrigation for more than half of the farmlands, development of the area, opening up new jobs. One very big problem though was the impact on the species of fish in the river. As most of them are migratory species, with the building of the dam they were stopped in their movement, thus they became restricted to the upper part of the river. Also, the water and composition of the water changed, and all of these things contributed to significant reduction of the populations of the native species of fish.
The Earth's temperature rises drastically as one travels deep inside the earth - so the warmest is the inner core, and after this it's the outer core. After this slightly less warm is the lower mantle and only then the upper mantle - which is the correct answer to this queston. But the next layer, the crust, is even colder!
