Answer:
D. Fossils of the Cambrian Period
Explanation:
The Cambrian Period (541–485.4 million years) is the period known for the explosion of life on Earth, when all the major phyla of multicellular organisms originated, and almost all the groups we find today, in a period of time geologically short.
The primitive faunas of this period had numerous morphological patterns, an immense variety of species, mostly soft-bodied animals, and new ecological strategies such as predation, burying themselves deep in the sediment and building complex, branched tunnels. They also featured some relatively large skeletal animals, such as trilobites, brachiopods, and
The three methods of determining latitudes are:
Celestial navigation - is the use of a celestial body such as the sun, the moon or a star at sight to know your location.
Sextant - is an instrument for navigation the uses two visible objects. The angle between the horizon and a celestial body will determine your location.
Octant - this is also an instrument used for navigation for calculation of angles.
Answer:
This is very positive mean.
Water is highly valuable in Eastern and South Africa because it is too expensive for the government to afford in a time of drought. Therefore, when they build water pumping stations to provide them with enough water, they need to place the wells in a specific location that is easily accessible for the local people to travel to and get enough for their family that is sufficient enough to last them the whole day.
Answer:
D. historical geology involves the study of rock strata, fossils, and geologic events, utilizing the geologic time scale as a reference; physical geology includes the study of how rocks form and of how erosion shapes the land surface
Explanation:
The geology can be separated into two sub-disciplines; physical geology and historical geology. The physical geology is the part of geology that has the present in its focus. It is examining the formation of the rocks, the volcanic eruptions, the earthquake activities, and even the effects of the pollution. On the other side, the historical geology is focused on the past. This part of the geology uses the geological time scale as its reference. It is examining the layers of the rocks, and through it tries to explain what happened in the past, how were the geological processes working. Also, the fossils are one of the main focuses because they provide lot of information about the environment in which they lived.
