Compressional or P (for primary) , Transverse or S (for secondary) , Love, and Rayleigh. Primary waves push and pull the ground in the direction the wave is traveling. Secondary waves travel in the same direction, but they shake the ground back and forth perpendicular to the direction the wave is traveling. Love waves move back and forth horizontally. Rayleigh waves cause both vertical and horizontal ground motion.

Based on the illustration, which two continents provide the strongest evidence for the movement of landmasses?
tatyana61 [14]

Answer:

South America and Africa.

South America and Africa are the two continents which provides a strong evidence for the continental drift because their sides has a specific structure which can be fit with one another. The east coast of South America and the west coast of Africa fit together like pieces of a puzzle. The rock composition of east coast of South America and the west coast of Africa also similar which gives us a strongest evidence for the movement of big land masses away from each other that occurs with the passage of millions of years.

How might an invasive species threaten biodiversity
nika2105 [10]

Answer:

The invasive s p e c i e s tend to diminish the populations of native s p e c i e s because they outcompete them, and also manage to disturb the ecosystem.

Explanation:

The invasive species can or cannot be dangerous for the native biodiversity, but unfortunately, it is the second one that is much more common. The reasons as to why the invasive species tend to threaten the biodiversity are that they often don't have a native predator that will control their numbers, outcompete the native species for resources, and the native species don't have defense mechanisms against them. These factors result in havoc in the ecosystem in a relatively short period, with the potential to totally destroy it and changed it.

There are thousands of examples of invasive species around the world, some much more obvious than others. The Burmese pythons in Florida for example, have started to overtake the a p e x predator niche from the alligators by directly attacking them. On the other side of the world, in Australia, the cats and rabbits have contributed to leading hundreds of native species on the verge of extinction, and if there hasn't been human intervention there is a very high chance that a lot of native species would have been already extinct.
