The correct answer is asthenosphere.
Explanation:
The Earth comprises four layers, that is, the crust, the mantle, the inner core, and the outer core. The magnetic field of the Earth is the amalgamation of the convection it attains from the Coriolis Effect and the outer core. The layer of the Earth where convection of the mantle takes place is the asthenosphere.
The right answer is the burning of fossil fuels.

True
Explanation:
It is correct to say that the deeper in the ground we go, the older things get. This statement is specifically valid in a terrain that has not been disturbed by tectonic activities.
<em>According to the law of superposition of strata "in a sequence of sediment, the oldest layer is usually at the bottom and the youngest is on top provided the area is undisturbed". </em>
Based on this law of superposition of strata, it clearly seen that the deeper we go down in the earth, the older things get.
Answer:

Answer:
A, B, C
Explanation:
Freshwater wetlands are defined as the lands which have natural supply of water for the whole season due to geological or ecological factors such as tidal flows, connections with groundwater or flooding rivers.
There are three main types of freshwater wetlands swamp, marsh and bog.
A Swamp are able to support tall shrubs, tress, herbs and mosses to grow . These are covered with floodd water or gently flowing water and waterlogged soils prevent woody debris to decompose completely.
Marsh is found near lake, tidal water or rivers and remain flooded periodically. Marsh are the grassy areas covered by shallow water and help to overgrown with coarse grasses, rushes and sedges.
Bog is defined as an area where moss or mots decomposes slowly and form peat . They are characterized by acidic waters, a floor covered by a thick carpet of sphagnum moss and spongy peat deposits. they are generally found in northern climates which support precipitation of water.
Hence, the correct answer is A, B, C.
