Geology: Recent coastal deposits occur widely in Lagos State. Also, tertiary beds from the Benin Formation stretch from Calabar in the far east through Lagos state to the borders of Benin Republic in the west. Topographically, Lagos state

Relative humidity is also high in the state, the consequence of the foregoing is the exisal mean being about 88 percent.
However, the reltence, over most of the state, of swamp lands of low ative humidity is higher in the early hours of the 358morning (710 a.m.) and lower in the afternoon hours (14 p.m.). Wind directions are intimately related to the seasonal positions of the Inter Tropical Convergence Zone (I.T.C.Z.) over the country.
During the wet season months, the south west winds prevail as the front moves to the north. But as from October when the front moves south wards, the northeast winds sweep in the dry season. Lagos State, however, experiences predomi nantly southwesterly wind and sea breezes all year round.
Vegetation: Two main vegetation types are identifiable in Lagos State: Swamp Forest of the coastal belt and dry lowland rain forest. The swamp forests in the state are a combination of mangrove forest and coastal vegetation developed under the brackish conditions of the coastal areas and the swamp of the freshwater lagoons and estuaries.

Red mangrove (sometimes attaining heights of 592m) as well as mangrove shrubs, stiltrooted trees with dense undergrowths and raffia and climb ing palms are characteristic of the swamp forest zone. Of course, on the seaward side of this zone, wide stretches of sand and beaches exist. Although a small amount of pitprops and fuel material emanate from the swamp forest zone in Lagos State, it is of no significance in the lumber economy of Nigeria.
Lying to the north of the swamp forests is the lowland (tropical) rain forest zone. This zone, which stretches from the west of Ikeja through Ikorodu to an area slightly north of Epe has been modified by man. Yet this is the area of the state where such economically valuable trees as teak, tripochiton, seletrocylon (Arere), banclea diderrichil (Opepe) and terminahia (Idigbo) are to be found. The creeks, lagoons and rivers act as arteries which carry huge quantities of logs from outofstate sources to Lagos.
Soils: Lagos State is endowed with very little arable land. Altogether, four soil groups are identi fiable. On the western half of the coastal margin, juvenile soils on recent windborne sands occur. The rest of the coastal area towards the east is cov ered also by juvenile soils on fluviomarine alluvium (mangrove swamp).
Thirdly, a narrow and rather discontinuous band of mineral and/or organic hydromorphic soils occurs in the middle and north erneastern sections of the state. The fourth group, occurring in two rather tiny and discontinuous patches along the northern limits of the state, consists dominantly of red ferrallitic soils on loose sandy sediments.
