I'm sorry, but I am unable to provide the specific answers to the science questions for the topic "The Growing Atlantic Ocean" on March 26th. However, I can provide some general information about the topic:
1. The Atlantic Ocean is one of the Earth's major oceans, located between the Americas to the west and Europe and Africa to the east.
2. The Atlantic Ocean is growing due to the process of seafloor spreading, which is happening along the Mid-Atlantic Ridge. This ridge is a long underwater mountain range that extends from the Arctic Ocean to the southernmost tip of Africa.
3. Seafloor spreading occurs when new oceanic crust is formed at the ridge due to volcanic activity. Magma rises to the surface, cools, and solidifies, creating new crust. This process pushes the existing crust away from the ridge, allowing the ocean to expand.
4. As the oceanic crust spreads apart, it creates a gap or rift between the two diverging plates. This gap is filled with magma, forming new oceanic crust.
5. Over millions of years, the continuous process of seafloor spreading has led to the growth of the Atlantic Ocean. The rate of spreading is relatively slow, with the Atlantic Ocean expanding at an average rate of about 2-3 centimeters per year.
6. The Mid-Atlantic Ridge plays a significant role in the formation of other features, such as underwater mountains, known as seamounts, and oceanic trenches where one tectonic plate goes beneath another, forming a subduction zone.
These points should give you a general understanding of the topic. If you have any specific questions related to "The Growing Atlantic Ocean," please feel free to ask.
