A student group collected physical data at six different sites along a coastal spit, moving from the proximal end (Site 1) to the distal end (Site 6). Their findings are shown in Table 1 below.
Table 1
| Coastal characteristics | Site 1 | Site 2 | Site 3 | Site 4 | Site 5 | Site 6 |
|---|---|---|---|---|---|---|
| Mean Pebble Diameter (cm) | 6.4 | 5.2 | 4.8 | 3.5 | 3.8 | 2.1 |
| Beach Gradient (degrees) | 12.5 | 10.0 | 8.5 | 9.0 | 7.5 | 6.0 |
Identify the two correct statements about the coastal data in Table 1.
