Why did people in some parts of the world develop more quickly than people in other parts of the world according to Jared Diamond?
Jared Diamond’s basic theory is that some countries developed more rapidly than others and were able to expand and conquer much of the world because of geographic luck.
How does Latitude impact the spread of ideas and technologies?
The idea is that populations at comparable latitudes experience largely similar climates, making it easier to adapt crops and domesticated animals and, consequently, humans and technology to new locations east to west.
How is latitude related to climate?
1. Latitude or distance from the equator – Temperatures drop the further an area is from the equator due to the curvature of the earth. In areas closer to the poles, sunlight has a larger area of atmosphere to pass through and the sun is at a lower angle in the sky.
Why is latitude so important for crops?
Vegetation growth peaks at higher latitudes than temperature, because ecosystems in high-latitudes are strongly energy limited, and therefore more sensitive to temperature and to the increased water availability in permafrost regions.
What is the impact of latitude on a country?
Latitude and Temperature At the equator, the Sun’s rays are most direct. This is where temperatures are highest. At higher latitudes, the Sun’s rays are less direct. The farther an area is from the equator, the lower its temperature.
Is cropping mixed?
Mixed cropping is also known as inter-cropping, polyculture, or co-cultivation. It is a type of agriculture that requires planting two or more plants simultaneously in the same field, interdigitating the plants so that they grow together.
How does mid latitude affect climate?
The area between the warm tropics and the chilly poles is called the mid latitudes. Climates in this zone are affected by both warm, tropical air moving towards the poles and cold, polar air moving towards the equator. Chaparrel: This ecosystem has wet-winters and dry-summers.
What is the average temperature in mid latitude?
The most pleasant climates occur in the temperate mid-latitude zone. Here summer temperatures rarely go above 40°C, and winters are usually fairly mild, on account of the influence of the warm westerly winds that originate from the subtropics.
What are the characteristics of mid latitude climates?
Moist continental mid-latitude climates have warm to cool summers and cold winters. The location of these climates is poleward of the “C” climates. The average temperature of the warmest month is greater than 50° F (10° C ), while the coldest month is less than -22°F (-30°C).
Why do mid latitude cyclones occur in winter?
This is because mid-latitude cyclones migrate further north during winter, allowing the edge of the cold front arm to sweep across the southern most part of the country. The interior is dry and cold in winter, with subsiding air from strong high pressure systems.
What are the four main characteristics of a developing cyclone in order?
Meteorologists have divided the development of a tropical cyclone into four stages: Tropical disturbance, tropical depression, tropical storm, and full-fledged tropical cyclone.
- Tropical disturbance. When the water vapor from the warm ocean condenses to form clouds, it releases its heat to the air.
- Tropical depression.
What is the difference between mid-latitude cyclones and hurricanes?
A hurricane usually contains an eye with sinking air, whereas mid-latitude cyclones have a center of low pressure with rising air. Both are areas of surface low pressure and both have winds moving counter-clockwise around their respective centers.
Do all cyclones have eyes?
Eye. The eye is the region of lowest surface pressure and warmest temperatures aloft (in the upper levels) – the eye temperature may be 10°C warmer or more at an altitude of 12 km than the surrounding environment, but only 0-2°C warmer at the surface in the tropical cyclone.
What are the different paths of typhoon?
A typhoon usually follows three different directions: straight, recurving and northward. A straight path is defined as a westward path; the storm will head toward the Philippines, the south of China, Taiwan and Vietnam. A storm that follows a recurving path will head towards the east of China, Taiwan, Korea and Japan.
How does the jet stream affect midlatitude storms?
When the jet is strong, there tend to be stronger storm systems. When the jet is very wavy, it also tends to move weather systems along less quickly – like water flowing along a meandering river – which can result in extremes of heat and cold, flooding and drought.
What would happen if the jet stream stopped?
Without a jet, then, the whole pattern of global temperatures would be different, with the air cooling much more gradually across the latitudes. One of the clearest features of Earth’s climate, the striking temperature difference between equator and poles, would be gone.
