Explain how the shape of a river's stream bed can affect the river's speed and its power to cause erosion.
Explanation: The shape of a river's stream bed affects the speed and eroding power of a river by influencing the amount of friction between the water flowing through the river and the stream bed below. Friction is the force that opposes the motion of one surface as it moves across another surface. In a river, there is friction between the flowing water and the stream bed beneath it. Where a river is deep, less water comes into contact with the stream bed, so there is less friction. The reduced friction means there is less opposition to the water's motion, so the river flows at a greater speed and has more kinetic energy for erosion. On the other hand, where a river is shallow, more water comes into contact with the stream bed, so there is more friction. The increased friction means there is more opposition to the water's motion, so the river flows at a lesser speed and has less kinetic energy for erosion. Also, the roughness of a stream bed covered with boulders and other obstacles causes the water to flow through the river in a turbulent fashion. This could cause the river to move slower in some cases or erode more in other cases.

Answer:
It changes the amount of friction there is. There is more friction where water is shallow, and less friction where water is not as shallow. The friction has the power to cause erosion as it causes movement of water.

What do you mean by biome?A biome is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate.
A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.
There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga.

Based on the information in the graph, explain what physical process causes the cell to change size.
Answer:
Osmosis
Explanation:
Osmosis is the process in which solvent molecules move from lower to higher concentration through a semipermeable membrane.
When a cell is placed in a hypertonic solution, the cell loses water and moves from higher concentration to lower concentration that is from inside the cell to the water solution and causes shrinking of cell.
Shrinking of cell means decrease in size of the cell along with the passing time and cell loses all its water.
Hence, the correct answer is osmosis.

The atmospheric temperature decreases when snow starts melting because the snow
melt
Answer:
The atmospheric temperature decreases when snow starts melting because the snow absorbs thermal energy from the atmosphere to melt.
Explanation:
The temperature of the air, the intensity of the sun, the speed of the wind, and the amount of humidity are the factors that influence the melting of the snow. The thermal energy in the atmosphere is absorbed by the snow because the temperature of snow is less than the temperature of the atmosphere. When the flow of temperature takes place, the energy also flows. The thermal energy helps the snow to melt because the snow requires warmth to melt.

Answer:
- Jason asked his fellow group members about their hobbies and interests .
- Jason and another member disagree on what their respective roles should be in the group.
- Jason resolved his differences with the other group members .
- Jason began working with the group members as a complete unit .
Explanation:
The correct order of Jason's actions in the stages of the development of his group would be as mentioned above. After the first step of the formation of the group, the next step is 'storming' in which the ideas are generated. Thus, Jason asks the group members regarding their interests and hobbies as it assists in the generation of effective ideas for problem-solving. The next step would be 'norming' in which the conflicts would arise due to disagreement regarding the respective roles of group members. Then, Jason as a team member would resolve the differences among the team members to reach a common solution. After everyone agrees upon the same idea, Jason can pursue working with the group as a complete unit. These stages are crucial for the effective development of the group and achieve desired results through cooperation and teamwork.

O c. Magma Chamber
O D. Aphanite
Answer:
D. Aphanite
Explanation:
A.P.E.X
An invasive igneous body is aphanite. Thus, the correct option is D.
What are Aphanite rocks?
Aphanite's are igneous rocks that were formed by rapid cooling in a volcanic or hypabyssal setting and are so finely grained that their individual mineral crystals cannot be seen with the unaided eye.
Very fine-grained, crystalline fabrics called aphanitic minerals are created when a magma solidifies in reaction to an exceptionally rapid loss of heat and dissolved gases. They are characterized by grains that are too small to be recognized without a petrological microscope.
Large crystals are known to be present in certain specific igneous rocks. The crystals in this type of rock are approximately the same size. Compared to aphanitic rock, which is known to have rocks with finer grain sizes.
So, the correct option is D.
