Insolation weathering is predominantly observed in areas with a large temperature gradient between night and day.

Freeze thaw weathering will occur in any region with sub zero temperatures.

Stress release weathering occurs predominantly in areas with high rainfall

The amount of rainfall has an influence on the chemical weathering rates in a region

Wind is not important for any weathering process

They have curved crests

They are always smaller than 20 cm in length

They range in length from a few meters to 1000s of m

Their internal structure is characterised by cross bedding

They are associated with tabular cross bedding

They typically occur together with groove casts

They have straight crests

The largest clasts would have required a current of ~700 cm/s to be eroded and the average sized particles would have required a current of ~12 cm/s

In reference to the photograph of this sample provided in Moodle, the paleocurrent direction was from left to right

The largest clasts would have required a current of ~400 cm/s to be eroded and the average sized particles would have required a current of ~120 cm/s

In reference to the photograph of this sample provided in Moodle, the paleocurrent was from bottom to top

The largest clast would have started to settle when the current slowed down to ~80 cm/s.  The average sized clasts would have started to sediment at ~30 cm/s
