Answer:
True
Explanation:
There are several factors that contribute to Costa Rica being so rich in biodiversity. These are:
1. Geographic position. Costa Rica is located in the Neotropics, which corresponds to the tropical areas of the American continent and, for this reason, receives more solar energy throughout the year.
2. Geological history. In the formation of the country, there have been several geological processes of volcanism and rising seabed (orogenesis), which have resulted in different types of soils, on which different types of plants grow.
3. Altitude. The mountainous system provides numerous and varied microclimates to which plants and animals adapt well.
4. Climate. The climate is determined by latitude, temperature, wind, air humidity, and precipitation. All these elements participate in the climatic characteristics of a specific place, and in our country they meet the ideal values for life, thus making us privileged in natural wealth.
<span>An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem. For example, plants or lichens sensitive to heavy metals or acids in precipitation may be indicators of air pollution. Indicator species can also reflect a unique set of environmental qualities or characteristics found in a specific place, such as a unique microclimate. </span>
1. more dense and thinner
Oceanic crust is naturally denser and thinner than continental crust, so in a convergent plate boundary, the oceanic crust gets subducted underneath continental crust.
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
