Answer:
The first step of seafloor spreading is when a crack forms in the oceanic crust.
Explanation:
Seafloor spreading occurs in ocean waters. The force behind its formation is the convection currents in the mantle beneath it. When there are more intense convection currents in the mantle, it manages to have a big influence on the crust above it and break up tectonic plates.
The first step in the seafloor spreading comes in the form of cracking up of the oceanic crust. The convection currents manage to push huge amounts of magma under very high pressure and the crust breaks up. After this happens, magma starts to rise toward the ocean floor, as it gets out in the water it solidifies, and since the process continues for millions of years, the new magma that rises is gradually pushing the rock from the older one away.
The sediments located in Heinrich layers contain almost exclusively<u> </u><u>ice</u><u>-</u><u>rafted</u><u> </u><u>detritus</u><u>, known as </u><u>IRD</u><u>.</u>
Heinrich layers are layers of sediment in the North Atlantic. These sediments have consist of high amounts of debris in Foraminiferida shells brought by ice. This composition explains how these layers function as a historical record of major ice releases.
These layers are formed from huge releases of ice of the Hudson Strait ice stream. The North Atlantic cores of sediment found in these layers are badly sorted and lack almost any foraminifera, being composed of primarily ice-rafted detritus (IRD).
These IRDs are described as sediments of no particular size that are carried by floating ice until they are introduced into the water and mix into the environment. This Ice carries debris located within it in the way a raft would carry a person, by allowing it to float on the surface of the water

Answer:
Yes, cloud cover is an important factor influencing the solar radiation
Explanation:
- <u>Length of the day and the angle of the sunshine </u>and place located on the sphere of the earth are also considered vital factors in the infrared radiation that reaches the ground and is transferred into space from the same processes.
- There exists a seasonal variation in the incoming and outgoing of long and shortwave energy of the sun which is related by the <u>earth rotation as a black body at the night.
</u>
- The latitude which is located close to the equator is getting most of the sun rays and have a longer amount of insolation reaching the ground.
- Thus the places located on the poles have a lower angle of incidence of rays hence there is less radiation and less amount of energy is generated due to the <u>snow has a very high albedo than the tropics</u>.
- To predict the weather analysis of clouds over the area needs to be taken care o as these influence the winds and temperature patterns. Like the formation of high and low-pressure areas over the lands.
Answer: Southeast Asia is a geographically expansive and populous region characterized by fascinating social and cultural variation. Particularly striking to the outside observer is the region’s ethnic and religious diversity. The majority of the countries in this region are home to dozens of different ethnic groups, many with their own distinct languages, cultures, and styles of dress. Many of these groups have their own systems of religious belief and practice as well.
Explanation: Hope it helps :)
