Lines of longitude, or meridians.
Lines of longitude.
False. Consider a car moving on the road, along the earth's surface. That is considered to be Vx or Horizontal motion or velocity. If the car were to move perpendicular to the earth's surface that would be Vy or Vertical motion and velocity.
Yes
Horizontal
The imaginary lines that form the earths grid system are called latitude and longitude lines. Latitude lines go horizontally from east to west, where longitude lines go vertical from north to south.

A Meridian or Meridian Line is an imaginary line drawn between two points. In geography these two points are an imaginary arc on the earths surface from the North to the South Poles. In astronomy it is an imaginary circle in a perpendicular plane to those planes of the celestial equator and horizon.
The movement within the Earth that causes buried rock to be exposed at the Earth's surface is called uplift. It refers to the vertical elevation of the Earth's surface.
The North and South Poles are indeed imaginary points on the Earths surface where the line of the axis of it's spin would pass through.
Yes. The invisible "axis" lies vertical directly through the Earth. It's tilted though, at an angle. (Explains why it's colder at the poles.)

70% or 80% of water covers the earths surface
