Which statement describes an Eckert IV projection.

. The Earth is not a sphere. The sphere is an approximation of the figure of the Earth that is satisfactory for many purposes. A spheroid describing the figure of the Earth or other celestial body is called a reference ellipsoid.

This means that instead of being of equal circumference in all areas the poles are squished resulting in a bulge at the equator and thus a larger circumference and diameter there. The oblate spheroid or oblate ellipsoid is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis. The force of gravity would pull the Earth into a perfect sphere shape but the fast rotation of Earth on its axis an imaginary line running from the North Pole to the South Pole reduces the effect of gravity on the equator.

Ellipse - Planets when move around the sun forms an elliptical path. Coordinated Universal Time UTC. The shape of Earth is in laymans terms a spheric one.

Earth is slightly flattened at the poles and bulged at the equator. Several models with greater accuracy have been developed so that coordinate. Is the study of the planet earth its structure and composition and how it has changed over time.

What term is used to describe the shape of earth most accurately Oblate spheroid How does the circumference of earth at the equator compare to the circumference that passes through the. The shape is rectangular. Terms in this set 37 Geology.

Actual Quiz Match each of the following to a choice 1. Some climate changes in Earths history were rapid shifts caused by events such as volcanic eruptions and meteoric impacts that suddenly put a large amount of particulate matter into the atmosphere or by abrupt changes in ocean currents. Which term describes the very slow change shape of Earths orbit from A to B as shown images below.

This is the most simple way to explain our planets geometrical form. The equator is an imaginary line that runs around the middle of the planet at its widest point. The size and shape it refers to depend on context including the precision needed for the model.

We still can see this during lunar eclipses Today scientists use geodesy which is the science of measuring Earths shape gravity and rotation. When is the south pole nearest to the sun. Therefore lost to the earth through what process.

The science that specifically attempts to determine Earths shape and size by surveys and mathematical means is called. Nitrogen oxygen and water. What term properly describes the shape of the earth.

The direction north is always straight toward the top of the map. Science that studies the measurement and representation of the curvature shape and dimensions of the Earth and locations of points on its surface. The North and South Poles are points.

Earths Shape Earths circumference and diameter differ because its shape is classified as an oblate spheroid or ellipsoid instead of a true sphere. Which of the following best describes Earths shape. Ozone and oxygen b.
