The answer is Mount Everest
1. Djibouti
2. Eritrea
3. Ethiopia
5. Somalia
Explanation:
The Horn of Africa is part of the African continent that has the shape of a horn, thus the name of it. It is located in the northern part of Eastern Africa. The area is mostly dominated by a high plateau, while the coastal parts have coastal plains. The four countries that occupy territory on the Horn of Africa are:
- Djibouti
- Eritrea
- Ethiopia
- Somalia
Ethiopia is the largest country in this part of Africa, and it occupies the central and western parts of it. Somalia is the second largest country here, and it occupies the majority of the eastern coast. Eritrea an Djibouti are the two smaller countries on the Horn of Africa, occupying its north and northeastern part.
because they're different ways
The igneous rocks are the basic material for the formation of the two other rocks types, the sedimentary and metamorphic rocks. These rocks are the first that form. They form from the magma that has cooled inside the crust, or by the lava flows on the surface. Over time, the weathering and erosion start to break them apart little by little, creating sediments from them. These sediments are the founding block for the formation of the sedimentary rocks. Once these sediments are exposed to certain temperatures and pressures they start to become compact again, which is made possible through the cementation process that keeps them together. As more and more sediments are merged together, the sedimentary rocks are formed, and they can come in multiple different types, sizes, shapes, as well as compositions, and structures.
By observing how seismic waves are absorbed and refracted, scientist have been able to work out where the properties of the earth change dramatically. our understanding of the internal structures of the earth and the size of its core is based on these observations.
basically:
size of core
structure of the earth I.e. the layers of the earth
and I think the last one is how the internal structure is changing? not sure on the last one but its still a solid guess.
