The geology of

gravels and silts
of the Lambeth, Thames and Bracklesham Groups which characterise the Hampshire Basin.

Hampshire Basin

Main article: Hampshire Basin

In the south, along the

habitats, a large area of which form part of the New Forest
.

Much of the coastal landscape of the Hampshire Basin results from

Solent
, which separates the Isle of Wight from the coast of Hampshire, is itself a flooded river valley, further erosion having broken the remaining chalk link with the mainland.

Chalk Downs

In the centre and north of the county the substrate is the chalk of the

insects, as well as arable agriculture. The hills dip steeply forming a scarp onto the Kennet valley to the north, and dip gently to the south. The highest point in the county is Pilot Hill, which reaches the height of 286m/938 ft. The rivers Test and Itchen flow from the downland through green valleys, both supporting trout
and other wildlife.

A series of east-west trending folds in the chalk to the north of the Hampshire Basin is controlled by faults in the underlying

Beacon Hill, Old Winchester Hill and Henwood Down.[2][3][4]

Around the chalk margins to the north are the Pewsey-Kingsclere Anticline and to the south the Dean Hill Anticline, Portsdown Anticline, Forest of Bere Syncline and Chichester Syncline.

Further north, beyond the downs, the landscape is again lowland clay and gravel heathland, though the north is generally greener and more diverse than the south.
