The International Date Line is located halfway around the globe at 180 degrees longitude and represents the boundary where one day changes to the next.Which was likely the most significant cause of the great famine in china between 1959 -'s 1961
A rigid rules and schedules ignored local growing conditions
B resentful farmers refused to work their feilds
C most land in china was not owned by the people
D the food produced was inequitably distributed
The answer is c.
The correct answer is - A rigid rules and schedules ignored local growing conditions.
The great Chinese famine is still discussed nowadays, and what were the actual causes for it. It seems that the strict and not very well thought through policies of the government in that period was the main cause because the planing was terrible, measures for protection of the crops were on a minimum, the amounts of certain product were projected for perfect conditions so any little disturbance would immediately cause a problem with starvation. The government blamed it all on the weather conditions, but it was just cover their terrible policies in the agricultural department. The starvation was so terrible that around 30 million people died and 30 million births were postponed.

There are many ways to get around a city or town. Sometimes, it's best to walk or to drive. Other times, it's easier to take public transportation. What's your favorite form of transportation in your home town? How could you improve this form of transportation in your neighborhood?
Answer:
There are many forms of transportation to get around, although my favorite would have to be by biking or car. Biking is a very efficient and great way to stay active. There is a slight problem when it comes to biking and that is there is hardly any areas around town that offer a space for biking. I have seen a slight change in some areas which have a biking lane although not all areas in the neighborhood offer this. I believe that there should be a biking lane in almost every area that does not have sidewalks. Another way of transportation is by car. This form of transportation should be limited due to the pollution put out. If a car is in use then it should be used wisely, such as a trip to the grocery store or should carry multiple people within the car that are going to the same place. In conclusion, these are just some of the ways that transportation by car and bike could be improved.
Explanation:
My favorite form of transportation is a bike or scooter. It's a comfortable, good means of transport, and we can drive it even on narrow roads and park it anywhere.
What are the means of transport?The means of transport are vehicles from which we can go from one place to another.
Common means of road transport are cars, auto, buses, trains, etc.
The means of air transport are airplanes and the means of water transport are ships and boats.
Thus, My favorite form of transportation is a bike or scooter. It's a comfortable, good means of transport, and we can drive it even on narrow roads and park it anywhere.

This tells us that that star is one of the brightest in the sky.
The apparent visual magnitude of a star is 7.3. This tells us that the star is not apparent to the human eye.
What is Star?Star is referring to luminous objects or celestial body which shines with their own light, unlike other satellites or planets which take light from Sun to shine In the galaxy.
As a result of our atmosphere's light-scattering characteristics, which distribute sunlight throughout the sky during the day, stars are not visible during those times. As our Sun's photon cloud thickens, it gets harder to see a distant star's weak light.
Even while the stars appear to be stationary, they are actually constantly moving and have been imaginatively associated with figures by ancient sky observers. Simply said, they are too far away for the human eye to see them move.

Rural areas are any areas that aren’t considered “urban.” Please select the best answer from the choices provided. T F
The correct answer is True. Rural areas are indeed defined as any areas that are not considered urban.
Urban areas typically have a high population density and large built-up areas, whereas rural areas have lower population densities and are often characterized by open spaces, agricultural landscapes, and small towns or villages.
The definition of what constitutes an urban or rural area can vary by country and the criteria used by statistical agencies, but the general distinction holds that rural areas are those outside of the urban context.

Approximately how much of earth's surface is covered by water (1 point)
The point within earth from which earthquake wave energy radiates is known by which of the following terms?
The point within Earth from which earthquake wave energy radiates is known as the a. 'hypocenter.'
The hypocenter, or focus, is the exact location beneath the Earth's surface where an earthquake begins. This is the point at which the crust or mantle first ruptures, releasing seismic energy that spreads out in all directions. The hypocenter is always located at some depth within the Earth.
The epicenter is directly related to the hypocenter. It is the point on the Earth's surface that lies vertically above the hypocenter. While the earthquake originates at the hypocenter, the epicenter is often the location where the effects of the earthquake are most strongly felt because it is closest to the source of the seismic energy.
Earthquakes often occur due to the movement along faults in the Earth's crust. According to the elastic rebound theory, stress builds up in rocks on either side of a fault until they eventually snap and release energy, causing an earthquake. This rupture starts at the hypocenter.
Seismology is the study of earthquakes and seismic waves. Seismologists use instruments called seismographs to measure the waves and determine the location of both the hypocenter and epicenter.

Ice wedging is a form of chemical weathering.
T or F
Ice wedging is not a form of chemical weathering. It is a process of physical weathering wherein water seeps into rock cracks, freezes, expands, resulting in further cracking. This is a physical, not chemical process.
Explanation:The statement, 'Ice wedging is a form of chemical weathering,' is False. Ice wedging is actually a form of physical weathering. It takes place when water seeps into the cracks of rocks, freezes and expands.
When the ice melts, it creates larger cracks. These processes repeat over time, resulting in the breaking down of rock substances.
This process does not involve any chemical reactions, thus it falls under physical, not chemical weathering.

Answer:
C. Scale
Explanation:
Scientists studying the effect of climate change can make use of wildfires as a simple case study.
Climate change is a global phenomenon because climate have predictable global patterns. Climate is highly affected by the global circulation and movement of air masses from one place to another.
If an activity in America such as burning fossil fuels is on the rise, the effect would not only be localized to that part of the world alone, agents of climates will randomly disperse the burden through a world wide global circulation pattern. This can be felt on a small scale by increasing wildfires in Australia.

How does the environment affect genetic factors and gene expression?
The gene expression of the organism may be affected by the environment. This includes the outside ecosphere where the entire creature and organism are situated or progresses, and also as the organism's interior ecosphere, these consist of the aspects of metabolism and hormones. Even though the structure of genes is unaffected by the environment, the gene expression (how the genes work) will be affected. Factors in the environment like drugs, foods, and toxins may result in some epigenetic changes by changing how the DNA bind by the molecules and the structure change of the proteins that the DNA wraps.
