Answer:
Grizzly bears have many other adaptations that help them find food and survive. For example, they have a distinguishing shoulder hump that is actually a mass of muscle, which enables brown bears strength to dig. Also, their claws are long, making them useful in digging for roots or digging out burrows of small mammals.
The correct answer is - Magma generated from a hot spot burned through the overlying plate to create volcanoes.
The Hawaiian Islands are all formed as a result of volcanic activity of a hot spot. The hot spot is stationary, but the islands are in the shape of a chain, not all in the same place. Also, the rocks on the islands that do not have active volcanoes are older, than the ones that do have volcanic activity. This suggests that the Pacific plate is moving. According the direction in which the islands are arranged, the Pacific plate seems to move toward northwest. As it moves, it moves over the hot spot. Since the hot spot is stationary, as the Pacific plate moves, eventually the volcanic activity will stop on the island that has moved further away from the hot spot. The magma from the hot spot will penetrate through the crust that came to be over it. That will result in new volcanic island emerging from the sea over the hot spot. The process goes on for millions of years, and it can result in hundreds of islands of volcanic origin.
#1) Sand grains can be distinguished from silt grain by ____.

The North Star appeared to move higher in the sky.
Answer: Option 3
<u>Explanation:</u>
North star is a special star found in the sky which is said to be fixed in the sky and does not move from it's place and the reason for this is that this star is very near to the axis of the planet Earth and is the only star that does not change it's position in relation to the rotation of earth. So since Albany is to the north of the New York city, the star will appear to move higher towards the north in the sky.
<span>The
causes of environmental problems in Sub-Saharan Africa are deforestation,
development, and increased population. As the country is aiming for development,
its environmental status is impaired. Increasing population resulted to
migration to higher urban or rural areas, and continuous land cultivation which
eventually caused deforestation and dilapidation.</span>
