Akilia Island, Western Greenland: 3,,, YBN: 45) The oldest sediment, the Banded Iron Formation begins. Banded Iron Formation is sedimentary rock that spans from to billion years ago, made of iron-rich silicates (like silicon dioxide SiO 2) with alternating layers. The southern limit of continuous sea ice, when at its maximum, probably stretched across the North Atlantic in a great are from Newfoundland past southern Greenland and Iceland to Ireland. Its position can only be conjectured. However, core sampling of the North Atlantic sea floor has revealed abundant stones and grit occurring in layers.

Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Among other factors, the diversity of all living things depends on temperature, precipitation, altitude, soils, geography and the presence of other study of the spatial distribution of organisms, species and ecosystems, is the science of biogeography.

Akilia Island in Western Greenland. The oldest evidence for life on earth was found in this rock by measuring the ratio of carbon 12 to carbon 13 in grains of apatite (calcium phosphate) from this rock. Life uses the lighter Carbon isotope and not Carbon and so the ratio of carbon to carbon is. Akilia Island, Western Greenland: 3,,, YBN: 45) Oldest sediment, the Banded Iron Formation begins. Banded Iron Formation is sedimentary rock that spans from to billion years ago, made of iron-rich silicates (like silicon dioxide SiO 2) with alternating layers of. Biodiversity, a contraction of "biological diversity," generally refers to the variety and variability of life on Earth. One of the most widely used definitions defines it in terms of the variability within species, between species, and between ecosystems. It is a measure of the variety of organisms present in different can refer to genetic variation, ecosystem variation, or. Biodiversity, a portmanteau of biological (life) and diversity, generally refers to the variety and variability of life on ing to the United Nations Environment Programme (UNEP), biodiversity typically measures variation at the genetic, the species, and the ecosystem level. Terrestrial biodiversity tends to be greater near the equator, which seems to be the result of the warm.

Geomorphology is the study of the earth's landforms and the processes that made the landscape look the way it does today. What we see when we look at a scenic view is the result of the interplay of the forces that shape the earth's surface. These operate on many different timescales and involve geological as well as climatic forces.
