After cloud droplets form what must happen to them for precipitation to occur?
For precipitation to occur, cloud droplets must grow in size and become heavy enough to fall out of the cloud as precipitation. This can happen through processes such as collision and coalescence, where cloud droplets collide and merge together, or through the process of ice crystal formation when the cloud is cold enough. Once the droplets grow large enough, they will fall as rain, snow, sleet, or hail, depending on the atmospheric conditions.
What are two processes that must occur to form soil?
Weathering, which breaks down rocks into smaller particles, and decomposition of organic matter, which enriches the soil with nutrients, are two processes that must occur to form soil.
Why can soil erosion lead to a malnourished population?
Soil erosion can lead to malnourishment in a population because it reduces the fertility of the soil, making it difficult to grow crops. This can result in lower agricultural productivity and reduced availability of nutritious food, ultimately leading to malnutrition and food insecurity in the affected population.
Where in the earths crust must a mineral occur?
A mineral must occur in the Earth's crust, which is the outermost layer of the Earth. This layer extends from the surface down to about 50 kilometers deep. Minerals are typically formed through geological processes in the crust, making this layer the most common place to find them.
What are the five levels of the environment?
Organism, Population, Community, Ecosystem, Biosphere.
What must occur for a population to grow?
For a population to grow, the birth rate must exceed the death rate, there must be enough resources available to support the increase in population, and factors that limit growth such as disease or predation must be controlled.
What must happen for specification to occur?
A population must be isolated in some way
What must be true for hardy equilibrium to occur?
mating must happen randomly
What must occur for a gene pool within a population to change?
A genetic mutation within the population.
What must be true for equilibrium to occur?
No disruptive circumstances must be present in random mating in a population for Hardy-Weinberg equilibrium to occur. Mating must happen randomly. No allele can give an advantage
What steps must occur for a seed to grow into new plant?
the plant is sexually reproduced ok
Which condition is necessary for a population to grow?
Birthrate must exceed death rate
What must occur for the gene pool within population to change?
natural selection or genetic drift
Which of these is one of the conditions for hardy-weinberg equilibrium?
Mutation cannot occur. Apex
Why must a population have a genetic variation in order for natural selection to occur?
Without variation there is nothing to select from.
What must be present for heat to occur?
there must be atom and molecule movement for heat and a suitable environment for heat to grow, such as, it should already be hot where the heat is occurring
What are the four things that must happen for natural selection to occur?
For natural selection to occur, there must be genetic variation present in a population, some of which is heritable. This variation must lead to differences in survival and reproduction (differential fitness). Individuals with advantageous traits must pass those traits on to their offspring. Over time, these advantageous traits become more common in the population.
