Answer:
The layer of greenhouse gases is permeable to one side and not permeable to another side.
Explanation:
Greenhouse gases such as carbondioxide, methane and water vapors etc formed a layer which allow the sun radiation to the earth surface but when these radiation reflected back, this layer traps these reflected radiation and the radiation remain suspended in air which heat up the particles present in the air and increases the temperature which causes global warming of earth surface. This phenomenon is also called greenhouse effect and it is also very useful in growing crops in cool seasons. So this layer is permeable from one side and not permeable from another side.
Answer:The Antarctic Treaty
Explanation:
<span>The correct answer for the question that is being presented above is this one: "Topographic maps feature contour lines to portray the shape and elevation of the land. Topo maps render the three-dimensional ups and downs of the terrain on a two-dimensional surface. It also includes contours. Orthophoto maps</span> show land features using color-enhanced photographic images which have been processed to show detail in true position. They may or may not include contours."
Answer: Cropping patterns
Explanation: refers to proportion of area under different crops at different points of time. It also indicates the time and spatial arrangement or sequence of crops and / or fallow in a particular land area.
These two theories are related because they are continuity from one another. The theory of plate tectonics insinuates that the crust layer is broken into multiple pieces, this is caused by the pressure of the mantle layer, which managed to break the crust where it is thinner. The theory of continental drift insinuates that the tectonic plates move around the Earth because of the pressure from the hot semi-liquid mantle layer.
