b. small buisnesses find it harder to compete
Answer:
The true statement is - Sympatric speciation only occurs in areas where there is local variation in environmental resources
Explanation:
- Sympatric speciation means the evolution of new species from an ancestor species which are occupying in the same area and no geographical barrier takes place.
- Overlapping of ranges takes place to the organism and old and new species are living i the same geographical region.
- A dam diving a fish population could lead to allopatric speciation where geographical barrier causes formation of new species which are completely different from their ancestor species.
Answer:
Global atmospheric pressure and wind patterns
Explanation:
It is a circulation of large scale movements of air mass over the earth by the means of solar energy. Wind belts are also connected to this pattern of air flow between high and low pressure belts like the Hadley, polar, and ferrel cells both in northern and southern hemisphere. the ITCZ area i.e the equator drives most of these winds and as result the warm air rises and colder air which is heavy descent thus leading to the formation of clouds which in turn is also impacted by the sun rays and spinning of the planet differently in northern and southern hemisphere. For example, as the warm current like japanese black or Kuroshio raise temperature in polar area's thus affecting the temperature extremes of the that area indirectly impacting the precipitation around the globe.
Answer:
The theory of plate tectonics is based on the movement of the tectonic plates by the convection currents, and this has led to the constant change of the physical landscape on Earth.
Explanation:
The theory of plate tectonics suggests that Earth's crust is divided into numerous pieces, called tectonic plates, and they are constantly moving because of the convection currents in the mantle. The convection currents are actually the ones responsible from break up the crust, and they are a circular movement in the mantle, where the cooler and denser material drops down, while the hotter and less dense material is pushed up and creates huge pressure on the crust.
Because of the pressure of the convection currents, the tectonic plates are in constant motion in a certain direction, creating three different types of plate boundaries, convergent, divergent, and transform plate boundaries. The different interactions between the plates have led to the creation or destruction of all sorts of landforms, from mountains and volcanoes, plateaus and valleys, lakes, and ocean basins... The movement of the plates throughout the geological past has led to the formation of supercontinents where the vast majority of Earth's crust has been connected, but also to breaking apart of them and continents scattered around the globe far away from each other.
