Answer:
1. The one nearest the surface is the "zone of aeration", where gaps between soil are filled with both air and water. Below this layer is the "zone of saturation", where the gaps are filled with water.
2. Larger pores mean less friction between flowing water and the sides of the pores. Smaller pores mean more friction between flowing water and pore walls and more twists and turns for the water to navigate. A permeable material has a greater number of larger, well-connected pore spaces. An impermeable material has fewer, smaller pores that are poorly connected.
3. A cave is any cavity in the ground that is large enough that some portion of it will not receive direct sunlight.
A cavern is a specific type of cave, naturally formed in soluble rock with the ability to grow speleothems.
4. The size of the pores underground rock material has and if the pores are connected
5. Karst regions are formed when there is a chemical reaction between the groundwater and the bedrock. As rain, streams, and rivers flow over the earth's surface, the water mixes with the carbon dioxide that naturally exists in air, and the soil becomes acidic and corrodes the calcium carbonate rock. The carbonate solution seeps into fissures, fractures, crevices, and other depressions in the rock. Sinkholes develop and the fissures and crevices widen and lengthen. As the openings get larger, the amount of water that can enter increases.
The four types of global winds are:
1. Jet streams
2. Polar easterlies
3. Westerlies
4. Trade winds

Answer:
50%
Explanation:
The allele for black fur (B) is dominant to the allele for brown fur (b).
- BB or Bb = black fur
- bb = brown fur
A male homozygous black mouse (BB) is crossed with a female brown mouse (bb). The male parent only produces<em> B</em> gametes and the female parent only produces <em>b</em> gametes. The F1 offspring will be 100% heterozygous Bb.
The F1 individuals will produce <em>B</em> and <em>b</em> gametes. If we cross the F1 individuals to each other (Bb x Bb), we'll get the following F2 offspring:
- 25% BB homozygous dominant
- 50% Bb heterozygous
- 25% bb homozygous recessive
So 50% of the F2 will be homozygous (BB or bb).
The correct answer is - True.
The matter is moved through the Earth by the interactions that appear between the Earth's systems. The lithosphere, hydrosphere, biosphere, cryosphere, and atmosphere, are constantly interacting between each other. Those interactions cause lot of matter to move around the Earth, both on its surface and inside of it.
The plate tectonics movement manages to move pretty much all of the matter on the planet, though it is a very slow process, it is very important one. The atmosphere with the movement of the air masses, as well as the waters from the hydrosphere, and the ice of the cryosphere, all manage to to move around lot of matter with their force, and that can be very slowly and on small distance, or quickly and on longer distances. The biosphere too, even though it contributes the least int he movement of matter, contributes to the physical movement of smaller amounts of matter from one place to another.
