Maps, Maps, Maps part 2

In today's reading I learned the definition of multiple words. The definition of map scale, projection, meridian, longitude, parallel, latitude, prime meridian, Greenwhich Mean Time, and International Date Line. The definition of map scale is the relationship of a feature's size on a map to it's actual size on Earth. Projection is transferring locations on Earth's surface to a flat map. Meridian is arc drawn between the north and south poles. Longitude is the location of each meridian is identified on Earth's surface according to a numbering system. Parallel is a circle drawn around the globe parallel to the equator and at right angles to the meridians. Latitude is numbering system to indicate the location of a parallel. The prime meridian is the meridian that passes through the Royal Observatory at Greenwhich, England, is 0 degrees longitude. Greenwhich Mean Time is the time at the prime meridian, is the master reference to time for all points on Earth. Lastly, International Date Line follows 180 degrees latitude, you move the clock back 24 hours.

Map scale is presented in three different ways which all show or describe the distances on the map and Earth's surface. The three ways it is presented is as a ratio, written, or graphic. A ratio shows the numerical distance between distances on the map and Earth's surface. A written scale describes the distance between the map and Earth's surface in words. A graphic scale is a line marked to show distances on Earth's surface. Map projection is transferring locations and longitude and latitude lines from the Earth to a flat map.

Longitude and latitude are used to locate points on a map because they are all based off of two lines; the prime meridian and equator. Longitude can be described using east and west and latitude can be described with north and south. Longitude and latitude are used to tell time because the Earth is divided into 360 degrees of longitude. There are 24 hours in a day so they divided 360 by 24 and got 15 degrees. Each 15 degrees on the map is assigned to a standard time zone so depending on where the place is related to International date line which is the central point that is what time zone you are in.

commercial agriculture

1.) Describe the basic principles of several forms of crop based commercial agriculture.  What is the idea of "agribusiness" and how does this idea contribute to agriculture in the developed world?  Agribusiness is the system of commercial farming found in developed countries because farming is integrated into a large food-production industry.  2.) Identify and describe the 6 forms of commercial agriculture in the developed world.  Grain farming- is heavily mechanized, conducted on large farms, and oriented to consumer preferences. these farms are also generally located in regions that are too dry for mixed crop and livestock agriculture Mediterranean Agriculture- this type of agriculture exists primarily on the lands that border the Mediterranean Sea in Southern Europe, North Africa and western Asia. Every Mediterranean area borders a sea. Prevailing sea winds provide moisture and moderate winter temperatures which is good for the agriculture here. Most ...

Temperature and humidity did play a role in the transmission of other diseases like the flu and chickenpox but it will not play a role in Covid-19. Physical distancing may have to be practiced for another year to see positive results and to slow the spread of this disease. Schimelpfening, Nancy. “Warm Weather Won't Stop the Spread of COVID-19.” Healthline , Healthline Media, 15 May 2020, www.healthline.com/health-news/warm-weather-wont-stop-spread-of-coronavirus#The-bottom-line. The virus is still a new virus so new information is being learned everyday but the studies from MIT  show that the weather can affect the spread of the virus. The st...

migration

1. Discuss the topics of push and pull factors and explain the cultural, environmental, and economic reasons for migration.  2. Describe the demographic characteristics of international migrants.  1. A push factor induces people to move out of their present location. A pull factor induces people to move into a new location. Cultural reasons could be for reasons like family status or schools. Some environmental reasons for migrating are flooding or desertification. Economic reasons for migration could be moving to a developed country that has things your home country does not.  2. Gender of migrants and age of migrants. Ravenstein theorized that males were more likely to migrate long distances. In developing countries male immigrants outnumber female immigrants. Ravenstein also theorized that most long-distance migrants were young adults seeking work. The migrants who were moving long-distance were normally individuals not families with children.
