In its path around the Sun, the axis of the Earth has an inclination:

varying between zero and 23° 27 with the plane of the pat.

Observed from a position on the surface of the Earth the heavenly bodies seem to:

move from East to West on the northern hemisphere.

move from West to East on the southern hemisphere.

not change their relative positions on the sky.

The direction of the Earth's rotation on its axis is such that:

An observer on the surface of the Earth always will face West when observing sunrise.

Any point on the surface of the Earth will move westward.

Any point on the surface of the Earth will move eastward.

Observed from the point above the North Pole, the rotation is counterclockwise.

is so small that it may be ignored when making ordinary maps and charts.

makes the difference between the polar diameter and the equatorial diameter about 22 NM.

The total length of the 30° Latitude is:

The angular distance measured along a meridian from the equator to a parallel of the latitude, measured in degrees, minutes, and seconds and named North or South.

The displacement of a place from equator.

The angle between the plane of the equator and the plane of the parallel of latitude.

The maximum difference between geocentric and geodetic latitude occurs at about:

The poles on the surface of the Earth may be defined as:

The points at which the vertical lines run through the center of the Earth.

The points where the Earth's axis of rotation cuts the surface of the Earth.

The points from where the distance to the equator is equal.

If an aeroplane was to circle around the Earth following parallel 60° N at a ground speed of 480 kt. In order to circle around the Earth along the equator in the same amount of time, it should fly at a ground speed of:

The arc at equator between the Greenwich meridian and the meridian of the place, measured in degrees, minutes and seconds, named East or West.

The East-West distance between Greenwich and the place.

The angle between the Greenwich meridian and the meridian of the place.

The difference between the Greenwich meridian and the meridian of the place, measured at the center of the Earth.

The diameter of the Earth is approximately:

The circumference of the parallel of latitude at 60° N is approximately:

Given: value for the ellipticity of the Earth is 1/297. Earth's semi-major axis, as measured at the equator, equals 6378.4 km. What is the semi-minor axis (km) of the Earth at the axis of the Poles?

The angle between the plane of the Equator and the plane of the Ecliptic is:

Consider the following statements on longitude.

Longitude is stated in degrees up to 360º.

The largest value of change of longitude is 90º.

The value of longitude will never exceed 90º.

The term Ellipsoid may be used to describe:

The movement of the Earth around the Sun.
