Correct Answer: Stope
Explanation:
These are called intrusive igneous rocks because the magma has intruded into pre-exiting rock layers. Types of intrusive igneous rocks are granite and basalt .
A batholith is the largest of the intrusive bodies.
Correct Answer: Renewable energies
Correct Answer: mass being converted to energy when protons and neutrons bind together in a nucleus
Correct Answer: Bicycle
Explanation:
Bicycle is a compound machine in the above given options. A compound machine is a machine that is formed by two or more simple machines.
Correct Answer: Conductors
Correct Answer: Scanning tunneling microscopes
Correct Answer: The Basic Speed Law states that you must never drive faster than is safe for present conditions, regardless of the posted speed limit For example, if you are driving 60 kmph in 45 kmph zone, you are not in safe driving and you just not following the speed law
Correct Answer: Nuclear energy
Correct Answer: If a micrograph is false-colored, it means that the computer has created the colour for the object since we know that the electron microscopes sees only black and white colours
Correct Answer: All of the above
Explanation:
All of the factors that contribute to global winds are
1) Uneven warming of the earth by the sun
2) Coriolis Effect
3) Convection Cells
