I think the thing that protects us from harmful radiation is ozone. Correct me if I'm wrong. Hope this helps tho!
From south to north Somalia has 30 rivers.
Answer:
<u>Tsunamis are killer waves of local, distant and regional types.</u>
Explanation:
- Tsunamis are tidal waves that move in series and cause displacement of large bodies of water, caused due to the landslides or tectonic shifts or volcanic eruptions, produced within the earth's crust. The gravitational pull of the sun and moon causes huge waves in the ocean waters which form wave high ranges.
- Mostly occurring in the Pacific and Indian oceans, local Tsunamis are those that cause damage in the proximity i.e within 100 kilometers. These can be very dangerous as they take about 10 minutes only to affect the people and hence no chance of predation or warnings.
- Regional Tsunamis are those that cause damage to the <u>100 to 1000 kilometers from underwater events</u>. As these provide more waning time than the earlier waves but less than 1 hour as they are within the area of 1000 kilometers.
- Distant Tsunamis are ones that are called Tele tsunamis or ocean-wide tsunamis they often occur with huge destructions and appearing like local Tsunamis but cover a vast expanse of the landmass. The most destructive type of Tsunamis was one on the ocean floor of Indians in 2004 occurring by the earthquake of 9.0 magnitude.
The best answer is D all of the above because rapid population growth and industrialization have effected the fresh water along with the animals that use/live in the habitat.
Answer:
Option (1)
False
Explanation:
The mid-oceanic ridge is one of the main features in the divergent plate boundary. Seafloor spreading takes place along this ridge, where the lithosphere becomes thin because of the uprising magma. The magma erupts at the surface forming a ridge which is commonly known as the mid-oceanic ridge.
As the magma melts at this ridge due to the decompression process, it solidifies and forms young basaltic igneous rocks. These are geologically the youngest rocks. With the increasing distance right from the mid-oceanic ridge, the age of the rocks increases.
Thus, the correct answer is option (1).
At this mid-oceanic ridge, when the magma erupts at the seafloor, it is comprised of magnetic minerals, which shows a specific pattern in the orientation of the earth's magnetic polarity. This forms alternate stripes, that starts from the mid-oceanic ridge and eventually expand outward. This pattern of earth's magnetic polarity is found in all the mid-oceanic ridges on earth.
Hence the given statement is false.
