Which description tells two processes scientists think move Earth's lithospheric plates? O convection in the mantle and pressure of magma on the edge of the plate O gravity acting on the edges of plates and friction between the plate and the asthenosphere O friction between the plate and the asthenosphere and pressure of magma on the edge of the plate O gravity acting on the edges of plates and convection in the mantle 2

answer; a male inherits only one allele of the x-linked gene controlling hair color;

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
