Answer:
Heat from the mantle forms convection currents causing the tectonic plates to diverge and form ocean basins.
Explanation:
Ocean basins form as a result of convection in the mantle along divergent margins.
- At a divergent margin, new crusts are being formed.
- It is said to be a constructive margin because new materials reaches through to the earth surface from there.
- The mantle convection pushes materials up and down away from heating centers and to cold regions and back and forth.
- This leads to the creation of cells which moves the overlying plate.
- The mantle materials are then able to reach the surface to form new ocean basin.
Answer:
B) Above average rainfall
Explanation:
The Southern Oscillation, also known as El Nino, brings in significant changes of the weather on all areas that are affected by it. Texas is also affected by El Nino, and that is manifested in milder temperatures and increased precipitation.
La Nina and El Nino have the total opposite effect on the weather conditions of Texas. While La Nina brings in warmer and drier weather conditions, El Nino actually brings in milder weather and much more rainfall.
Texas in general is semi arid. The temperatures are mild in winter and high in summer, with the rainfall mostly being absent for most of the year, and the majority of it falling intensively and seasonally. When El Nino is active though, Texas receives much more rainfall, making its temperatures lower in the process as well.
This is actually welcomed by the Texans, as the increased rainfall is good for the agriculture. The people are happy as well that they have lower temperatures for some time, so they are experiencing extremely high and unbearable temperatures.
If the land was big and flat. The soil would need to be moist and fertile. Other factors would need to be the area. Is it shaded or can the sun shine through so the plants can grow.
