Answer:
<u>Wegener gave many evidence to the theory of plate tectonics another piece of evidence was the finding of fossils of reptiles in oceans and glossiperious fauna and the similarity of glaciers in all continents</u>
Explanation:
- Alfred Wegener is supposed to believe that the supercontinent named Pangaea consisting of northern continents and the southern continent i.e Gondwanaland consisting of southern continents were once the same.
- Thus he gave evidence in the shape of puzzle-like fit of the continents as similarity of rocks found in the continent's of Africa and South America, as they were one earlier.
- Further, he gave the supporting pieces of evidence as the glacier landmasses distributed were the same part earlier drifted away from the larger continent of Greenland.
- The supporting evidence the put forth was the polar wandering forces that he called the flight from poles and drift under the impact of moons gravity and another evidence was the thin sheets or plate moved away due to the wind.
Answer:
A.) A warm ocean current flows along the coast
Explanation:
The sea ports which remain ice-free are called "warm-water ports." Other than those that can be found in Europe, warm-water ports can also be found in <em>New York</em> and <em>Canada.</em> This is due to the<u> warm ocean current that flows along the coast in these areas</u>. This allows the area to be free from ice, thus ships can just come and go. It is said that the "Gulf Stream" is responsible for bringing the warm water to Europe. However, other countries have cold-water ports just like in Russia.

Answer:
Inflitration of water deep into a slide mass increases landslide hazars.
Explanation:
Infiltration causes landslide that create hazards in people through property damage,remediation costs.
Lans slides are common in hilly and mountain region.
The large size of water shed allows significant amount of infiltration by melting the snow into the hill slope region.
The hydrological properties that are present in soil causes change in steepness of the dip bedrock located below the land slide.
These factors control the direction, speed, and the amount of ground water that travels through the slope.
