Why is September 11, 2001, a significant date in US history? Al-Qaeda carried out the largest terrorist attack against the United States on this date.
It is the date that Congress passed the Patriot Act authorizing sweeping surveillance powers.
It is the date that the US military launched a "war on terror" in Iraq and Afghanistan,
Al-Qaeda leader Osama Bin Laden was killed on this date by US military forces.

it deviates because of the date.

explanation:

the international date line is an imaginary zig zag line on the surface of the earth roughly following the 180 degree meridian. crossing the date line causes the date to be changed exactly by one day. crossing the line from east to west , one loses a day . and from west to east, one gains a day.

the correct answer is - they each vary in size and temperature.

the layers of the earth are not monotone, they are all different, have different sizes and properties.

the four layers are the outer crust, the mantle, the outer core, and the inner core.

the outer crust is solid. it is the top layer, the one we live on, and it is also the smallest and coldest one.

the mantle is lying right bellow the outer crust. it is much bigger, and much hotter, and it is also the layer that influences heavily the upper crust layer with its convection currents.

the outer core is liquid, very hot, relatively big, and it is the third layer (top to bottom).

the inner core is the hottest layers, it is occupying the central part of the planet, and it is the basis on top of all other layers lie on.
