If the sun were reduced to the size of a grapefruit, earth on the same scale would be:_______.
If the sun were reduced to the size of a grapefruit, Earth on the same scale would be approximately 15 meters away from the Sun, about the size of a ballpoint pen's tip.
What is size of Earth?Only one astronomical object, Earth, is known to support life, and it is the third planet from the Sun. Despite the fact that the Solar System is filled with a lot of water, only Earth is home to liquid surface water. The oceans cover around 71% of Earth's surface, dwarfing its lakes, rivers, and polar ice. The shape of Earth is not perfect. An oblate spheroid, that is. Near the poles, it is flattened, while at the equator, it is rounded. The distance between the poles and the equator is 12,714 kilometers (12,756 miles). This comes out to 13,000 kilometers.

Turbidity currents are great masses of sediment-laden water that are pulled downhill by?
Turbidity currents are great masses of sediment-laden water that are pulled downhill by gravity.
According to this theory, the oceans formed when water vapor and other gases escaped from Earth's lava into the atmosphere surrounding the cooling planet. After the surface of the earth cooled to a temperature below the boiling point of water, it began to rain and continued to rain for centuries.
Factors controlling sedimentation include particle size and turbulence in the sedimentation environment. Terrestrial sediment-laden water is a good reflection of its origin and is carried to the sea by winds, rivers, and glaciers. The rate of erosion is important in determining sediment composition.

When water evaporates, the energy that was used to evaporate the water is stored as:._____.
When water evaporates, the energy that was used to evaporate the water is stored as latent heat in the evaporated water.
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes to the gas phase. The high concentration of volatiles in the surrounding gas slows down evaporation significantly, for example when humidity affects the rate of evaporation of water. When the molecules of a liquid collide, they transfer energy to each other depending on how they collide.
When a molecule near the surface absorbs enough energy to overcome the vapor pressure, it escapes and enters the surrounding air as a gas. When evaporation occurs, the energy removed from the evaporating liquid lowers the temperature of the liquid, resulting in evaporative cooling.
On average, only a fraction of the molecules in a liquid have enough heat to escape from the liquid. Evaporation will continue until an equilibrium is reached when the evaporation of the liquid equals its condensation. In a closed environment, the liquid evaporates until the surrounding air is saturated.

In summer, at the same pressure, maritime tropical air is less dense than continental tropical air.
What is maritime tropical air?The most significant air mass that produces rain and moisture throughout the year is the maritime Tropical (mT). It goes poleward in the winter and is cooled by the ground. As a result, it is distinguished by rain, low stratus or stratocumulus clouds, fog, and limited visibility.

How do the different methods used to calculate population density reveal different information about the pressure the population exerts on the land? Give examples
Answer: Population density shows location of people, growth, and the flow of people.
Explanation: Arithmetic is the number of people divided by the total land area. Arithmetic density compares the population of one area to another. In a city there is more likely to have a greater arithmetic density than the suburbs.
Physiological density is the population divided by arable land. Physiological density shows how much population a certain area can sustain.
Agricultural density is the amount of farmers divided by arable land. This shows how much arable land can support active farmers

When two plants with red flowers are mated together, the offspring always are red, but two purple flowered plants are mated together, sometimes the offspring have red flowers. so here purple color is dominant.
The remarkable diversity of mating patterns and sexual systems in flowering plants has fascinated evolutionary biologists for more than a century
Much theoretical work on mating system evolution has focused on conditions favoring the evolution of self-fertilization within populations, such as reproductive assurance when pollen transfer opportunities are limited and the genetic transmission advantage of selfing in populations with low inbreeding depression .
Conversely, high rates of outcrossing are thought to be favored when the cost of inbreeding depression exceeds the transmission advantage of selfing.

Why did Russia hand over East Germany?By 1948, the Soviet Union was attempting to starve West Berlin with a blockade. This prompted the US-led Berlin Airlift, and the Soviets relented nearly a year later.
However, the schism between East and West Germany only widened. Each side established its own government, and in June 1953, Soviet tanks assisted the East German government in suppressing a worker's uprising.
The greatest affront to the West was the construction of the Berlin Wall in 1961, and the Soviets supplied the might to keep it standing. When Soviet power began to wane in the late 1980s, so did the Wall.
It was finally brought down in November 1989, when East Germany's Communist regime collapsed amid popular protest and economic weakness.

The effects of climate change on human health have been seen and are expected to be considerable. The amount to which the links between climate change and health are taught is still unknown, despite the fact that climate change has gained worldwide momentum and is routinely taught. Public awareness of these issues can be raised through education, but it is unclear how much of this potential has been realized historically in terms of climate health education. We suggest conducting a scoping review of all instructional methods used to illustrate the health effects of climate change between 2005 and 2017 to fill this knowledge gap. This review would coincide with a turning point in the public health and climate change agendas after the 2005 Group of 7/8 (G7/8) Summit and the medical students are the most important part of it.
What is climate change?Current climate change encompasses both the effects of global warming on the planet's weather patterns. Although there have been times of climate change in the past, the current rate of change is noticeably faster and is not the result of natural factors. Instead, it is brought on by the release of greenhouse gases, primarily methane and carbon dioxide (CO2). The majority of these emissions are produced by the burning of fossil fuels for energy. Additional sources include particular industrial operations, agricultural methods, and forest loss. The Earth's surface is heated by sunlight because greenhouse gases are transparent to it.
