Answer:
Jet stream
Explanation:
Jet stream is fast moving air or wind that blows horizontally through the upper layers of the troposphere, generally from west to east. It develops where air masses of different temperatures meet. The greater the difference in temperature, the faster the wind speed.
Jet stream has the following characteristics;
- The winds blow from west to east
- The flow often shifts to the north and south.
- They follow the boundaries between hot and cold air.
Answer:
oceanic and continental
Explanation:
Earth's crust is divided into two categories, oceanic crust and continental crust. The oceanic crust is the one that is found in the oceanic plates, thus it is predominantly covered with water, while the continental crust is the crust that forms the continents, thus it is predominantly above the water. The oceanic crust is located slightly lower, they have higher density, but have lesser thickness. The continental crust is located slightly higher than the oceanic crust. This crust is significantly thicker, but it has lesser density, which is why it ''floats'' above. These two types of crust are constantly in interaction with each other, and when there is a collision between the two, the oceanic crust subducts below the continental crust. This results in the oceanic crust to move downwards to the mantle and get molten, thus destroyed, while the continental crust experiences uplift near the plate boundary. Other consequences are the emergence of volcanic island arcs and volcanic continental arcs, as well as intense earthquake activity.
Answer:
D) in volcanic eruptions, plate movements thrust hot magma up into Earth's crust, where it cools and hardens.
Explanation:
Plate tectonics influences the formation of metamorphic rocks because it is produced in the process of subduction. In subduction process, volcanic eruptions, plate movements push hot magma up into Earth's crust, where it cools and hardens due to low temperature. Due to this process of subduction, plate tectonic movements causes the formation of metamorphic rocks in the earth.
Tectonic activities occur mostly at or near the areas near the surface of the earth where tectonic plates meet. These plates are like slowly shifting pieces to a puzzle that makes up the earth's outer skin. <span>Activity can also occur where the Earth's liquid mantle comes particularly close to the surface. </span>
Sorry that I'm no help lol
