Answer: d. A bar graph indicating average high and low temperatures for Amanda’s area in the autumn, winter, spring, and summer.
A scientific study requires the use of variables, on the basis of which the outcome of the study can be obtained. An independent variable refers to a variable which can be changed or manipulated in an experiment, such changes will affect the dependent variables. Dependent variables is the outcome of the research, it cannot be changed manually instead the changes occur are because of the changes in the independent variable.
In the given situation, a bar graph indicating average high and low temperatures for Amanda’s area in the autumn, winter, spring, and summer would be an effective scientific model to be incorporated in the Amanda project. This is because of the fact that both independent and dependent variables can be analyzed by this way. The temperature is an independent variable, which changes with respect to the climatic conditions, which represent a particular season like autumn, winter, spring and summer which is a dependent variable.
The process that moves small rock pieces during the sedimentary rock formation is erosion.
The carrying away of small rock particles by the effect of wind, water or ice.It is a surface phenomenon on the earth's crust and then the transportation takes place.
This is a natural phenomenon caused by the dynamic activity of the agents that can cause erosion.
