Hi, Seaford cliffs are chalk/flint; and the geology is from the Cretaceous period. Google 'geology seaford' and see what you come up with!
Also check http://www.discoveringfossils.co.uk/locationsSE.htm - there's not much detail, but it gives you a little bit of information. Seaford's towards the bottom of the list.
Good luck with your homework!

From a geological point of view East Sussex is part of southern anticline of the Weald: the South Downs, a range of moderate chalk hills which run across the southern part of the county from west to east and mirrored in Kent by the North Downs. To the north lie parallel valleys and ridges, the highest of which is the Weald itself (the Hastings beds and Wealden Clay). The sandstones and clays come the sea at Hastings; the Downs at Beachy Head
Relief and drainage
The relief of the county reflects the geology.
The coast
From west to east along the coast between Brighton and Eastbourne are the gradually rising chalk uplands, with breaks at Newhaven where the River Ouse enters the sea; and likewise at Cuckmere Haven. The cliffs beyond here are named the Seven Sisters, Sussex, and are the remnants of dry valleys cut into the chalk; they end at Beachy Head, 162m (530ft) above sea level. To the east of Beachy Head lie the marshlands of the Pevensey Levels, formerly flooded by the sea but now enclosed within deposited beach. At Bexhill the land begins to rise again where the sands and clays of the Weald meet the sea; these culminate in the sandstone cliffs east of Hastings. Further east are the Pett Levels, more marshland; this followed by the estuary of the River Rother. On the far side of the river is Camber Sands.
Inland
The southern part of the county is dominated by the South Downs; its highest point is Firle Beacon, 217m (712 ft) above sea level. The northern part is dominated by the High Weald. Between the Downs and Weald is a narrow stretch of lower lying land, before the southern slopes of the Weald, through which the rivers mentioned above flow. The highest point in the county is Ditchling Beacon, at 248m/814ft.
