Carboniferous

The Paleozoic Era was the first in the Phanerozoic Eon. In the Paleozoic Era all life lived in or around water. This is because land was not sustainable for life yet.The Paleozoic Era had six different periods. The Era lasted about 542 million years but ended because of the Cambrian explosion. The first period in the Paleozoic Era was the Cambrian Period. The Cambrian Period was an important part of Earth’s history and formation. It was when mainly all of life first came around. The second period

occurred. The time period was named as it was by a British geologist named Roderick Murchison in 1841. He went on a tour to Imperial Russia to include the, “vast series of beds of marl, schist, limestone, sandstone, and conglomerate” overlay the Carboniferous formations in the eastern part of Russia. Murchison named it after the kingdom of Permia, and the present city of Perm near the Ural Mountains of Russia. During this period, Gondwana and Euramerica formed Pangea. The collision of tectonic plates

sister taxa to all living jawed vertebrates. Placoderms evolved from agnathan (jawless) fishes in the Silurian period, about 425 million years ago. They first appeared in the Early Silurian and diversified dramatically during the Devonian and Carboniferous periods and became extinct in Permian.

The common land plants are thought to have originated 450-500 million years ago from a group of freshwater green algae called charophytes (Domozych). These algae emerged on land and thus spawned the first plants, bryophytes. Bryophytes are non-vascular plants who first appeared 354-409 million years ago in the Devonian period, and are only found on land (Evolution). Since they lived on land, they had little support and relied on their cells’ turgor pressure to keep them upright (Evolution).

Coal is a natural resource that is made up of carbonized plants that is found underground in coal pockets. Coal is used as fuel in numerous things, including electricity generation, steel production, and cement manufacturing. Coal is very flammable, so it's great for producing energy. Coal contains things like hydrogen, sulphur, oxygen and some amounts of nitrogen. Those ingredients make coal extremely flammable. Coal happens to be a very important tool in the factory business. Many different places

coming from Permian reservoirs, which are sealed by the upper Permian salt. The development of this basin is resulted of the subsidence, which has been punctuated by discrete events of uplift and predominant erosion in several periods such as Late Carboniferous, Late Cretaceous, as well as at several times during the mid-Cenozoic (Cameron et al. 1992, cited in Balson et al. 2001, p.10). Some of the episodes are not completely clear when they occur, for instant, extensional events with different stress

Fossil Fuels and Their Impact on the Environment The amount of fossil fuels being deposited into the air should be controlled. Not only do fossil fuels pose a threat to the environment, but also to human health. The problem is not only noticeable in the depletion of human health, but also in the air, water, and land. Emissions are a concerning contribution to other problems such as global warming and greenhouse gases as well. One of the major factors of fossil fuels are vehicles. Vehicles

Cambrian: • This period started 540 million years ago and ended 500 million years ago. • There was a very mild climate. The supercontinent Rodinia began to break into smaller parts, or continents. Lots of glaciation occurred so many animal families went extinct. • All phyla develop during this time period. Many marine animals, shell-fish, echinoderms, and some of the earliest fish appear. • Lots of glaciation occurred wiping out many animal families marking the end of the Cambrian period.

Week 1 Critical and Creative Thinking Questions Name: Gardner Chapter 1 3. How do you think the principle of uniformitarianism accounts for occasional catastrophic events such as meteorite impacts, huge volcanic eruptions or great earthquakes? Uniformitarianism is a scientific clarification on how the rocks, continents and mountains in the planet are created. The material process that occurs on earth has not changed; although the objective conditions have changed radically the principle

The contribution of cockroaches in the ecosystem. What will happen if there were no cockroaches? Cockroaches are one of the ancient species, it begins to be found from the Carboniferous period, about 320 million years ago [1]. It belongs to the group of Blattodea, undering the category of Inseacta. Most of us has seen cockroaches, we often see them hiding inside the dark and humid place in our home, including the kitchen, toilet or the gutter. Every time we see them, we would never be nice to them
