There are several ice ages that has taken place here on earth. Recent studies of ice ages have interpreted glacial events by analyzing the oxygen isotope ratio in marine sediments.
- The Ice Age is a very popular timeframe in history. It is known to be a long time of decreasing in the temperature of Earth's surface and atmosphere.
This can also lead to the presence or expansion of continental and polar ice sheets and alpine glaciers.
The Earth's climate is said to often alternates inbetween ice ages and greenhouse periods. In this period, there will be no glaciers on the planet.
Scientists have recorded at least five important ice ages in the Earth's history.

Answer:
The Earth is an oblate spheroid, bulging out slightly at the poles
Explanation:
- Earth's surface structure is in the form of geoid of three-dimensional structure. As the earth's topographic features are associated with landform and water bodies.
- Hence earth is not a complete sphere nor a perfect sphere its a form of oval-shaped epllicics and thus has an ellipsoid revolution and a tilt around the sun on its axis.
- The bulge at the equator is a product of the spinning of the earth and modern geodesy takes this ellipsoidal as a spheroid.
Explanation:
A hard boiled egg is made up of shell, egg white and the yolk.
The shell is the tiny calcic-cover round the egg that protects the internal component. It is a very thin and brittle layer. The thinnest of all.
This corresponds to the crust. The crust is also brittle and it is in the outer most part of the earth.
The egg-white part is the largest part of the egg. It is relatively softer than the shell.
This can be likened to the mantle. The mantle is the largest portion of the internal part of the earth
The inner most part is the yolk. It is similar to the inner core of the earth. It is thicker than the crust.
