<span>Case study: Boxing Day Tsunami, 2004. On 26 December 2004 a tsunami occurred in the Indian Ocean. It was the result of the Indio-Australian Platesubducting below the Eurasian Plate. It was caused by an earthquake measuring more than magnitude 9.</span>
Answer:
a. They must be present in a large geographic area.
Explanation:
Index fossils can be used to determine the age of a rock strata with great precision, but they must be scattered over a large geographic area to be able to be used reliable for this type of measurement. Index fossils typically indicate a certain type of paleoenvironment belonging to a very specific prehistoric period and their formation coincides with the age of the rock layer.
I'll start by listing why the other ones are incorrect.
B- A national banking system.
The government isn't a bank anymore. It used to have a national bank, but government is much more than that.
C-Basic unit of currency used by the European union
The government isn't a type of money.
D-<span>the ability to deal with situations and issues without provoking hostility
The government has this ability, but that's not what government is.
__________________________________________________
Correct:
A-A form of system of rules.
This is the basic definition of government.
Hope this helps!

Answer:
- May be it was formed by faulting using the compression forces and hence formed due to the reverse faults formed
- Or, it was formed due to downwarping
Anyways it would have been better if you added the picture of the valley
Answer:
The baseball would seem to be traveling with a velocity 0.98918c of 98.92% of the speed of light as seen from the Earth.
Explanation:
This problem involves the relativistic effects. The pitcher throws the ball with a velocity u' which is 65% of the speed of light c i.e. u' = 0.65c
The velocity V of the spaceship in which he is practicing is 95% of the speed of light. Therefore V = 0.95c
So if the ball is thrown in the same direction as the direction of the spacecraft's motion, then classically, the velocities would add up and exceed the speed of light. But we know that this is not possible. It is prohibited by the special theory of relativity. So we need to consider the relativistic addition of velocities to calculate the velocity (u) of the ball as seen from the Earth.
The formula for relativistic addition of velocities is expressed below,
We know that u' = 0.65c and V = 0.95c. now we can calculate u which is the velocity of the baseball as seen from Earth as follows
u = 0.98918c
So the baseball would seem to be traveling with a velocity 0.98918c of 98.92% of the speed of light as seen from the Earth.
