As the temperature lowers the molecules slow down and form into a crystal. The total volume of actual h2o is smaller. The reason the ice cube is larger than its relative size in liquid form is due to gaps the crystal structure creates. The higher density and crystal structure makes solids of any molecule much harder relative to its liquid counterpart. This goes for every liquid vs. solid.

The very oldest rocks discovered to date were found in 2008 in Northern Quebec, along the Hudson's Bay coast, 40 km south of Inukjuak.

There are other locations around the globe that have rocks around the 3.8 billion years old (and older!) mark, some in Austrailia, Africa and other places in Canada.

The countries most affected during the last glaciation were those countries which still experience snow and ice during the winter. That is most of the North American continent, most of Europe and Scandinavia, Russia, northern China and Japan.

Yes

EDIT

Depends which "Ice Age" you mean. The earliest and longest ice age was the Cryogenian period which began over 850 million years ago and lasted until 635 million years ago. Even "cryo" refers to the cryosphere; the amount of ice on the Earth. In relation to your question, it would be no. The Ice Age the answerer above is probably referring to is the times when the Wooly Mammoth dominated in the Pleistocene period that began over 2,500,000 years ago and ended over 11,000 years ago.

As we are still in an ice age which began 2.6 million years ago I presume you mean "glaciation".

The overall average temperature has risen otherwise we would be sitting on 1km thickness of ice.

Temperature change tends to vary depending on which part of the earth you look at, 4-6 degrees C in East Africa and 2-3 degrees in higher latitudes. Areas receiving rainfall during times of glaciation are now quite dry as the weather systems move with the retreating ice.

A pillow lava is a lava which has been erupted under water. Because of the cooling effect and pressure of the water it forms pillow-like structures which sometimes build up into thick deposits. Ancient deposits can be found all over the world, though newer lavas can be found in areas such as Iceland where a combination of ice caps and volcanism create suitable places for pillows to form.

The word 'creation' means 'to bring in to existence' or 'to come in to being'. Life cannot exist without a medium, and the earth has not always existed. Therefore, regardless of your religious views, the creation of the earth must have occured before dinosaurs evolved or were created, excepting those (rather strange) faiths that believe that the earth always has been and always will be, as well as those which believe that all change is illusory.

Dinosaurs existed well over 60,000,000 years ago and the myth of Creation first started a few thousand years ago. So dinosaurs.

The Quaternary is the most recent geological time period, which started 1.67 to 2.4 million years ago depending on the area studied. The Quaternary is part of the Cenozoic ("new life") Era, along with the Tertiary Period. The Quaternary Period includes recent time (the last 11,000 years ago, since the last ice age) which is called the Holocene and the Pleistocene Epoch.

There is currently much debate as to how long the Quaternary period is. There are considerations into re-classifying the Quaternary as it is "technically" too short to be considered a geological age. But this is a matter of much conjecture at the moment.

The present ice age started over 2.5 million years ago and we live in a warm interglacial period within that ice age.

The last interglacial ended less than 120,000 years ago, so as far as Scotland is concerned, the last glaciation started about 115,000 years ago.

There was a warm period about 14,700 years ago but glaciers returned at 12,900 years, (Loch Lomond Readvance) and only started warming again 11,500 years ago.
