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.
Answer:
A, C, D
Explanation:
The Gulf Stream is a warm ocean current in the Atlantic that carries warm water from tropical latitudes towards the more northerly latitudes of Western Europe. The effect of this current on the climate of the western part of the European continent es enormous. Many European cities at the same latitudes as Canadian cities with sub-polar climates enjoy temperature cool climates thanks to the moderating effect of the Gulf Stream that reduces the continentality and high latitude effects of the location.
A. its the reason why the sun is up longer in the summer.
