D. intensive irrigation i guess well i have the same question
Factors that determine the rate of stream erosion-
➡️ Rainfall (more rain more erosion). ✔️
➡️water velocity ✔️
➡️shape, size and depth of channel ✔️
➡️stream capacity to transport eroded material, and the nature of the material being transported✔️
➡️Gradient (Steepness or slope) ✔️
➡️Discharge (Amount of water carried at a given time) ✔️
➡️Load (The materials carried by a stream)
Rainfall (more rain more erosion). ✔️
➡️Slope (the steeper the slope the faster the water will flow) ✔️
➡️Geology (if the bedrock is a soft silt it will erode faster than granite).✔️
Answer:
A: if it’s mobile (is able to move)
C: if it contains cilia (tiny hair-like projections that help it to move and eat)
D: if it is green in color
Explanation:
Just did it on edge 2020 ;D hope this helps
Explanation:
It is less dense when frozen than when it's a liquid.
Water freezes at 0°C, therefore the water molecules form a lattice crystalline structure maintained by hydrogen bonding. This Ice formed is less dense than water because the orientation of hydrogen bonds causes molecules of the ice to push farther apart hence lowering its density.
It takes a lot of energy to raise the temperature of water.
Specific heat capacity is the energy is takes to raise 1 mole of a substance to °C. For water, its specific heat capacity = 4.18 kJ/kg°C
Water molecules sticks to each other.
Forces of cohesion is the property of water molecules to stick to each other. Also, Hydrogen bonds are formed between adjacent water molecules because of the positive charged hydrogen end of one water molecule attracts the negative charged oxygen end of another water molecule.
It is a good solvent because both polar and nonpolar molecules dissolve in it.
Water is a univeral solvent because it dissolves a lot of solute unlike any other solvent. Water does not dissolve non-polar molecules because no hydrogen bond can be formed between them.
Answer:
A
Explanation:
The energy carried by electromagnetic waves is sometimes referred to as radiant energy. Electromagnetic waves do not require a medium for propagation hence they can travel through vacuum and are known to transmit enormous amount of energy.
Electromagnetic waves transmit energy away from the source of the wave. Hence the answer chosen in the answer section above.
