Answer:
b) the Pacific plate has carried the volcanoes away from the hot spot that formed them
Explanation:
The Hawaiian islands all have volcanic origin. Some are not active, while some still are. All of these islands have been active volcanoes at one point of time, and they have been created by a hot spot that lies beneath the Pacific plate. The hot spot has such a power that it actually manages to break through the central part of the plate where its crust is the strongest and densest. As the magma manages to come out above the water, it manages to create volcanic islands. The Pacific plate though is moving, it is not static, so it drags the volcanic islands away from the hot spot, causing their extinguishing. As those islands are moved away, the hot spot creates new volcanic islands, and the process constantly continuous, resulting in a volcanic island chain.
Answer:
Though there is no lake or river flowing through Sam's region,
Explanation:
Environmental quality refers to the features and the properties which are ideal for a good environment. The characteristics may be either in a generalized tone or in the local aspect. These characteristics help in maintaining the life of living organisms. The quality of air, water, and sound can be stated under the features of environmental quality.
In the given passage, the quality of air in Sam's region meets good environmental quality. On the other hand, the region does not have any lake or river. Since any water body is absent, therefore, the given sentence depicts the poor environmental quality.

scorched earth policy that the British used against Boer commandos that led to the
weakening of their resolve. Prior to
this, families were also rounded up and placed in camps guarded by the British
which demoralized the Boers.
Answer:
A - Pacific plate
B - North American plate
C - African plate
D - Eurasian plate
Explanation:
Plate tectonics theory explained the plate movement and evolution from 65 million years ago which is pre cambrian era. There were seven major plates in the world such as Pacific plate, North American plate, South American plate, Eurasian plate, African plate, Indo Australian plate and Antartic plate. There were three movements in the plate such as Convergence plate boundary, divergence plate boundary and Transform plate boundary. Pacific plate is biggest plate among all.
