Match the causes with their effects.
Cause: Radiogenic heat rises to heat molten magma,
Cause: Tectonic plates at transform boundaries experience friction
Cause: Earth is covered by a crust that runs miles deep.
Effect: The mantle is insulated from the atmosphere
and retains tremendous heat.
Effect: Magma at the core-mantle boundary rises and
convection currents are formed.
med.
Effect: Pressure builds up, eventually leading to an
earthquake

The bond energy for the van der waals bond between two helium atoms is 7.9×10−4ev. assuming that the average kinetic energy of a helium atom is (3/2)kbt, at what temperature is the average kinetic energy equal to the bond energy between two helium atoms

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.
