It can be confusing to know the difference between era and period, but the more that you know about it, the more that you will understand why they are used differently. A period refers to a large interval that has existed in a time that has already ended. The period has usually made significant changes to history and how everything works right now. Without this, everything can be highly confusing for a lot of people.
Era refers to the time interval wherein someone has ruled over a particular area. This is more commonly used in Asia than in other parts of the world. The main difference between era and period is that era does not necessarily refer to a long interval as compared to the period, which means that the time interval is prolonged.
Geology and ecology are two branches of science that have many similarities, but there are many differences too. If you have ever gone outside and picked up a rock and studied it, you are doing something about geology. Both have to do with the environment and everything that is on the planet. However, geology is considered to be an earth science.
Anything that makes up the earth even if it is a liquid or solid has to do with geology. Ecology, however, has to do with how life on earth, whether it is a human, animal, or plant interacts with other organisms on the planet. This has to do with where these living things live, what they eat, how they get food and their environment.
A water table is the upper level of an underground surface in which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone that lies below it. It varies both with the seasons and from year to year because it affected by climate changes and by the amount of precipitation used by vegetation. It is also affected by withdrawing excessive amounts of water from wells or by recharging them artificially.
The water table is where the water pressure head is equal to the atmospheric pressure. It is the top surface of the zone of saturation, which is where the pores and fractures of the ground are saturated with water. Water tables are the surfaces that exist between unsaturated ground and land that has become saturated with water. Most of the water exists below the water table.
The hydrologic cycle begins with the evaporation of water from the surface of the ocean. As moist air is lifted, it cools and water vapor condenses to form clouds. Moisture is transported around the globe until it returns to the surface as precipitation.
The sequence of conditions through which water passes from vapor in the atmosphere through precipitation upon land or water surfaces and ultimately back into the atmosphere as a result of evaporation and transpiration — called also hydrological cycle.
Water cycle, also called hydrologic cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff
It might be tempting to assume that mass can be determined by sinking a rock into a measuring cylinder of liquid, but only the volume can actually be determined that way. Simply, the volume displaced by the object pushes the level of liquid up so that the before and after measurement will give the volume of the object accurately. So the answer to the question is volume.
Aristotle and Plato are both known to have different theories that the average person may not be able to think about. They were able to go beyond their senses and to think about the world in a different light. Plato had the belief that sometimes, the things that people sense will be enough to fool people.
For example, if you like someone, you will feel that everything that the person does has a significant meaning even if there isn’t any. Aristotle believed that the senses are needed by people so that they can correctly assess reality. Aristotle also believed that some things do not have to be related to each other while Plato believed that everything in this world should coexist.
Letter C is the right answer among the choices. Intrusive igneous rocks are made from magma that are in the Earth’s crust. These rocks are cross-grained due to they have a slow cooldown time. One can easily identify the rocks as they are coarse and have large particles.
Extrusive igneous rocks, on the other hand, are made from lava and formed on the surface of the Earth. Because of this phenomenon, these rocks cool more quickly than the intrusive rocks as they are on the surface of the planet that has several factors that can contribute to solidifying them at a faster rate. The result is the lava or extrusive igneous rocks, are finer and smoother.
