Rotation is a vector having a direction and magnitude.
counterclockwise
Simply put, a vector is 2 dimensional. Think of speed - it is only one dimensional. It is not a vector, it is a scalar. It is measured in a scale, most commonly noticed when inside a vehicle. You are travelling at 100km/h (60mph) Vectors are 2 dimensional, they have a magnitude and a direction. Think of velocity, as an arrow - imagine you are travelling at 60 mph in a northerly direction, your arrow would be pointing to the notth, with a magnitude of 60mph, If you were travelling at 60mph in a southerly direction, your velocity vector would be pointing towards the south, the exact opposite of your vector if you were travelling in a northerly direction. However the speed in these two scenario's, speed not being a vector, remains exactly the same, 60mph.
1/4 of 360 degrees = 90 degrees which is a right angle
The rotation of a tornado is it spinning or turning. A tornado is defined as a violently rotating column of air in contact with the cloud base and the ground.

scalar lol
A scalar times a vector is a vector.
vector
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
current is vector or scalar
scalar direction is a vector quantity

An earthquake is neither a scalar nor a vector. It is an event.
Distance is a scalar. But displacement is a vector.
Since you can represent that with a single number, it isn't a vector - just a scalar.
