Population density allows for broad comparison of settlement intensity across geographic areas. When comparing population density values for different geographic areas, then, it is helpful to keep in mind that the values are most useful for small areas, such as neighborhoods. For larger areas (especially at the state or country scale), overall population density values are less likely to provide a meaningful measure of the density levels at which people actually live, but can be useful for comparing settlement intensity across geographies of similar scale.
Hope this helps <3
Central America does not produce wheat, rye or canola or apples or bauxite for aluminum or fir lumber but it does produce many tropical fruits like mangoes, papayas, guavas, oranges, limones, and vegetables like avocados and cilantro and cumin.
France and Spain are the two countries
Answer:
When two oceanic plates collide one oceanic plate is eventually subducted under the other. Where one plate slides under the other is referred to as the 'subduction zone'. As the subducting plate descends into the mantle where it is being gradually heated a benioff zone is formed. This benioff zone is a zone of shallow,intermediate and deep focused earthquakes. Some deep focused earthquakes that occur at ocean ocean- collision boundaries can be as deep as 670 kilometres. As the subducted plate descends into the mantle it is gradually heated allowing the formation of magma. The magma that forms is andesitic in composition and begins to form when the subducted plate reaches a depth of 100 kilometres. This andesitic magma is formed from the partial melting of the asthenosphere just above the subduction zone. This partial melting of the subducting plate is due to the loss of water as it descends into the mantle. The andesitic magma is now less dense than the surrounding material so it rises through the crust and erupts to form an arc of volcanoes called an island arc. The distance between the trench and the island arc depends greatly upon where the subducting plate reaches the 100 kilometer depth. If the subduction angle is steep then the distance between the arc and the trench will be short.If the suduction angle is shallow the distance is longer. The main features are indicated in the diagram below. The swell is seen by a bulge in the in the downgoing plate where it is subducted into the mantle.where the plate subducts into the mantle is known as the trench.the forearc ridge contains highly deformed sedimentary and metemorphic rock. The backarc region is located behind the arc and can be compressed or extended.

Answer:
hello your question has some missing diagrams attached below is the missing diagram
1) Intrusive contact ( A )
2) Gneiss ( D )
3) Principle of Cross-cutting relationship ( D )
4) Principle of Inclusion ( D )
Explanation:
1) The contact between the granite and the Gneiss represents an Intrusive contact
2) The oldest rock unit in the cross-section is Gneiss
3) The principle that allows for the distinguishing of the age relationship between Gneiss and Diorite is : Cross-cutting relationship
4) The principle that allows for the distinguishing of the age relationship between the Gneiss and the granite is : Principle of inclusion
