This photograph shows a protion of the Monahans Sandhills in northwest Texas. Monahans Sandhills are noted for their sand dunes
that can be up to 21 m (70 feet) high. The Monahans Sandhills are part of a semi-arid ecosystem that received 310 mm (21 inches) of rain on average per year.
Another picture of the same area taken weeks before shows that the shape and location of some sand dunes have changed. Which of these most likely caused the changes in the dunes?
A. mechanical weathering of rocks
B. wind erosion of sand particles
C. water deposition of pebbles
D. chemical weathering of the rocks

The question is incomplete as the image and options are not given, however, the correct image and options are as follows:
A. If liquid Material A is in contact with gaseous Material A and the volume of the gas increases, the gas’s temperature will increase.
B. If liquid Material A is in contact with gaseous Material A and the volume of the gas increases, the gas’s temperature will decrease.
C. When the temperature of gaseous Material A increases, its volume will increase.
D. When the temperature of liquid Material A increases, its volume will increase.
Answer:
The correct answer is - C. When the temperature of gaseous Material A increases, its volume will increase.
Explanation:
The figure and table related to the given question are attached with the answer that shows the volume change during the time period in relation to temperature and the phase of material also changes with an increase in temperature.
According to Figure 1, it is clear that initially, Material A was in the liquid phase and after a certain temperature, it is constant at a phase of a mix of liquid-gas and finally entirely in the gas phase from Time 22 sec to Time 24 sec. as temperature increased and the volume of Material A also increased according to the table 1.
So the hypothesis C is correct.
