Antarctic Plate

<p style="color:#dbdbdb ;padding:20px; border-left:5px solid #7f7f7f;">The Antarctic Plate is a tectonic plate, which encompasses the continent of Antarctica and further stretches outward under the surrounding oceans. The Plate borders the African Plate, the South American Plate, the Nazca Plate, the Indo-Australian Plate and the Scotia Plate. Creating the Pacific-Antarctic Bridge, it has a different border with the Pacific Plate. </p<>

African Plate

<p style="color:#dbdbdb ;padding:20px; border-left:5px solid #7f7f7f;">The African Plate is a major tectonic division of the earth’s crust, which includes the African continent as the linear ocean basins, namely, the Canary, Cape Verde, Angola, Cape Agulhas, Somali, Madagascar, and Natal Basins. It borders the Eurasian and Arabian Plates to the north, the mid-ocean ridges including the Southwest Indian, Mid-Ocean and Carlsberg Ridges on the east, the Mid-Atlantic Ridge on the west and the Antarctic Plate on the south.</p>

Thermosphere

<p style="color:#dbdbdb ;padding:20px; border-left:5px solid #7f7f7f;">Reflecting the parameters of the earth’s atmosphere, the general assumption is, ‘as the altitude increases, the temperature decreases’. However, there is an exception to this phenomenon. If we consider the layers of atmosphere like Troposphere, Stratosphere and Mesosphere, it gets cooler as we go higher. However, it is in the Thermosphere that we find the temperature inversion. Here, the temperature increases with height. The fourth layer, Thermosphere, is above the Mesosphere and below the Exosphere. The air in the layer is so thin that scientists find it difficult to measure its temperature. Hence, in order to ensure accuracy, they first measure the density of air by measuring the drag on the satellites and use them to determine the temperature.</p>
