An endotherm, also called as a warm-blooded organism, has the ability to generate heat internally. One advantage to being an endotherm, instead of an ectotherm, is that an endotherm can generate its own body heat. This kind of organism can create a favorable level of body heat that is independent of its environment. Endotherms include mammals and birds.
ORIGINAL SCIENCE
Explanation:
- Science is an enterprise building term that organizes theories and knowledge in the form of tests and predictions based on the universe.
- Ancient Egypt and Mesopotamia were the roots in which science was discovered in around 3500 to 3000 B.C.
- Modern sciences are divided into three sciences and they are
SOCIAL SCIENCES( ECONOMICS, PSYCHOLOGY)
NATURAL SCIENCES (BIOLOGY, PHYSICS, CHEMISTRY)
FORMAL SCIENCES( LOGIC, MATH)
- Original science was first termed as NATURAL PHILOSOPHY and the scientists of this science were termed as NATURAL PHILOSOPHERS.
- The English word scientist was termed by WILLIAM WHEWELL in the period of the 19th century.
The process that moves small rock pieces during the sedimentary rock formation is erosion.
The carrying away of small rock particles by the effect of wind, water or ice.It is a surface phenomenon on the earth's crust and then the transportation takes place.
This is a natural phenomenon caused by the dynamic activity of the agents that can cause erosion.
Answer:
The correct option is A. Measuring radioactive decay of element isotopes
Explanation:
At the time of formation of rock, certain kinds of radioactive isotope elements get trapped in the rock. These radioactive isotopes are unstable and decay over a period of time forming daughter elements. A rock which will have more number of radioactive elements will be newer to a rock containing non-radioactive daughter elements.
The radioactive decay of each element can be measured by the half-life of elements. This is the primary technique to determine the absolute age of a rock.
