The agent of erosion, which carried sediments that scratched bedrock is A MOVING GLACIER.
Agents of erosion refers to those forces that cause erosion. There are basically four agents of erosion, these are wind, running water, glaciers and gravity.
Glaciers are large sheet or block of ice that move along a landscape. Glaciers are powerful agents of erosion; moving glaciers are capable of removing loose rocks on their way of movement. They can also pick up and move particles of varying size. Moving glaciers usually carry sediments which scratch and polish bedrocks surfaces.
Answer:
In primary succession newly exposed or newly formed rock is colonized by living things for the first time.In secondary succession an area previously occupied by living things is occupied by living things is distributed-disrupted-than recolonized following the disturbance
example is eruption of volcanoes, the big island of hawaii. As lava flows into the ocean,new rock is formed
Ben walks to college every day. While participating in a race, he observes that his breathing rate is <u>higher</u> than his breathing rate when he walks. He also notices that his breathing rate is <u>lower</u> when he lies down.
In this statement, the term "breathing" refers to the gaseous exchange that occurs during inhalation, where CO₂ (carbon dioxide) is released, and exhalation, where O₂ (oxygen) is taken in. The process through which cells produce energy is referred to as "respiration".
Breathing is controlled by the autonomic nervous system, which ensures a synthesis between the actions of the sympathetic system by accelerating the respiratory rate and reducing amplitude, as in Ben's case when participating in a race. Meanwhile, the parasympathetic system is slowing down the respiratory rhythm and increasing amplitude, as in Ben's case when he is lying down.
