Scientists have discovered that the inner core of Earth is a solid while the outer core is a liquid. What is the cause of this observation? (4 points) a
The outer core has a higher temperature and more pressure than the inner core

b
The outer core has a lower temperature and lower pressure than the inner core

c
The inner core has a lower temperature and higher pressure than the outer core

d
The inner core has a higher temperature and lower pressure than the outer core

Temperature and kinetic energy are proportional. a) adirectly b) directly c) indirectly

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
