Answer:
it was part of the ocean it needs water
Answer: A. cooled and hardened lava from volcanoes
C. sediments deposited by rivers and ocean currents
An accretion is a process in which new materials are added to a tectonic plate or landmass. This process causes the enlargement of the landmass. The materials being added includes sediments, lava from volcanic eruptions and other materials from other sources.
The process of accretion can enlarge the size of a continent along its edge. The new land comes from the cooled and hardened lava from volcanoes and other reason is sediments deposited by rivers and ocean currents.
Yes it is advantageous for scientists to be able to predict harmful algal blooms.
<h3><u>Explanation:</u></h3>
Algae are minute plant like organisms that are unicellular, belonging to Kingdom Protista. The uncontrolled growth of algae over the water bodies is referred to as algal bloom.
Algal bloom has several bad effects. Although they are plants and growth of plants are good for environment, but growth of algae covers up the water surface, restricting the sunlight to enter the inside of water killing aquatic plants, as well as restricting oxygen dissolution, restricting the survival of aquatic animals. Its called eutrophication.
Algae sometimes also produce toxins which are harmful for both aquatic animals and unfit for human consumption. So the prediction of toxic algal bloom can led to taking measures to curb the bloom and saving the animals and plants from being death.
