How do materials move within the earth.
statuscvo [17]

The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

<h3>How do materials move within the earth?</h3>

The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.

So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

Base your answer to the question on the information below and on your knowledge of biology.
vodomira [7]

Answer:

They can perform photosynthesis.

Explanation:

Autotrophs are organisms that can produce their own food, and heterotrophs are organisms that feed on other organisms. This means that the ameba and paramecium can eat only other microorganisms.

The euglena is not limited to this. Hypothetically speaking, if there were no other microorganisms around it (which is unlikely), the euglena would not die as long as it is exposed to sunlight. Thanks to chloroplasts, organelles that contain chlorophyll, it can perform photosynthesis - a process in which, with the help of sunlight, carbon dioxide, minerals, and water are used to synthesize food.
