No ONE direction ALWAYS. The direction of the Earth's axis changes over the eons. The pattern that the axis draws on the celestial sphere is roughly circular (the precession) making one revolution about every 23000 years but there are small dips too (nutations) which complicate matters.
Right now the axis points almost towards the star we call Polaris (it pointed closes sometime in 2007). in 11000 years it will point close to the star we now call Vega.
Earth's axis of rotation is precessing, so that the direction in which the north pole points is tracing a circle in the sky. But that's happening so slowly that during the course of a person's lifetime, it appears to point permanently toward the same spot. That spot is presently very close to the star called Polaris ... the 'North Star'.
The earth's axis always points to the same distant point in the sky. (Well, actually it changes slowly
over thousands of years, but we're ignoring that slow change for right now.)
So, as I was saying, the earth's axis always points to the same distant point in the sky, and
that direction is not perpendicular to the plane of our path around the sun . That means that
when we're on one side of the sun, the top of the axis is tilted toward the sun, and when we're
on the other side of the sun, the top of the axis is tilted away from the sun.
Yes. The rotational axis makes an angle of about 66.5 degrees with the orbital plane.
For some reason, a lot of people feel that it should naturally be 90 degrees.
Parallelism of AxisThe earth is constantly rotating as it revolves about the sun. It rotates on an imaginary axis. The earth's axis always points in one direction. Thus as the earth revolves about the sun, the position of the axis at any one time is always parallel to the position it occupied at any previous time. This phenomenon is called parallelism of axis.It always points to the pole star.
True

It's called the 'coriolis' effect.

counter to the earth's rotation Exactly wrong..........it travels WITH the Earths rotation.....eastwards
The constellation is the the Big Dipper (USA) or the Plough (UK).
It means that the earth revolves around the sun
There is change of seasons when earth revolves about the sun.
Because Earths axis is tilted.
Every 100,000 years or so, the Earths magnetic field shifts direction. North becomes south, south becomes north.
East to West
A body wave is a seismic wave that travels through Earths interior.
