Sad to say, the warning time that the residents of Sumatra had before the 2004 tsunami hit land was close from little to none. A rough estimation would around 15 - 30 minutes. They say that the primary cause would be that there wasn't any warning systems over the Indian Ocean at that time. Another thing, which is what most people who knew about it would point out as the real problem, is that there was no issuance of a warning in the first place. The quake was detected an hour or so before the tsunami occurred in the Pacific Tsunami Warning Centre located in Ewo, Hawaii. At that moment, the information was relayed to Australia and to the rest of the world. The question wasn't why the Centre didn't issue a warning, but why the whole world network of information didn't issue one. They say that other sophisticated data were available at that time and almost immediately since the tsunami was active.
Answer:
<em>When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the </em><u><em>Earth's surface.</em></u><em> However, since the Earth is much cooler than the Sun, its radiating energy is much weaker infrared energy.</em>
Explanation:
Answer:
D)
Explanation:
Divergent plate boundaries occur when two tectonic plates are moving apart, such as the Eurasian Plate and the North American Plate. As the plate move apart energy, can be released as an earthquake. In the place of the lithosphere that is being dragged apart, magma can seep through as a volcanic eruption. In some cases the new volcanoes can for mountains along the middle of the Atlantic Ocean, dividing the tectonic plates. It can also cause a rift valley.
Answer:
<u>Two types of gis data representation method are raster and vector</u>
Explanation:
- In a GIS the data that is represented by the pints, line, and polygons is raster data and it's stored in the real world like phenomenon also known as the discrete data.
- Raster data is made up of pixel values and attributes that are associated with its color values, data is represented by the grids of cells. Stores spatial data more
- Another type of data model being the vector model that focuses on lines, polygons and area points are expressed by the single point reference. For example, cities on a map. A line like the rivers the roads the railroads, trails, and topographic and polygons include the lakes, park boundaries, buildings, etc.
- Vector data is most compatible with the relational database environments. Vector file sizes are hence usually very smaller than raster data. Raster data is computationally less expensive as compared to vector graphics. Stores nonspatial data.
