Answer:
You should conduct more research and assume that the text book may have incorrect information!
Explanation:
1) heat from radioactive decay in the core of the Earth heard the mantle.
2) Plates move averagely only a few cm a year, this has been happening ever since the planet formed and cooled to give a thick crust so this movement has added up over many years to move plates far from where they started.
3) because the mantle is heated and is able to flow slowly, convection currents are set up which cause the plates on the crust to move.
Answer:
No
Explanation:
Cities are a part of a country there may be some that were countries or are their own country but the answer should still be no.
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
1. Waves hitting at an angle and then bending around features of the coast is known as wave refraction.
2. Landforms associated with longshore drift form where the sediment is plentiful enough to create them.
3. When there is longshore drift, the overall direction of sand transport is parallel to the coast..
4. In order to produce longshore drift, the direction of waves must not be perpendicular to the coast.
5. A baymouth bar forms when longshore drift creates a ridge of sand separating a waterway from the ocean.
6. The direction that sediment is traveling along a coast is called the downstream direction.
Explanation:
Waves forms different kinds of land form in the coastal areas. Waves hit coast in a particular angle It is known as wave refraction. When sediments get deposited in the coastal areas and forms a bar which get detached from the shore is called long shore bar.
To create long shore drift the direction of wind should not be perpendiular to the coast. Direction will be parallel. A baymouth bar is formed when a ridge of sand is created and separates the waterway from ocean. Sediments travel along the coast in downstream direction.
