Answer:
continenetal crust
Explanation:
Magma Page 2 the densest type of crust (3.0 g/cm) and is made up of a metamorphic rock called basalt. Continental crust makes up the continents and rests on top of oceanic crust. Continental crust consists of less dense rock such as granite.
Answer:
237.9 amu
Explanation:
Given data:
Abundance of U-234 = 0.0054 %
Abundance of U-235 = 0.7204%
Abundance of U-238 = 99.2742%
Average atomic mass = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) + (abundance of 3rd isotope × its atomic mass / 100
Average atomic mass = (0.0054×234)+(0.7204×235) +(99.2742×238) /100
Average atomic mass = 1.2636+ 169.294+ 23627.2596 / 100
Average atomic mass = 23797.8172/ 100
Average atomic mass = 237.9 amu.
Answer:
The Earth’s lithosphere, which includes the crust and upper mantle, is made up of a series of pieces, or tectonic plates, that move slowly over time.
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge and Pacific Ring of Fire are two examples of divergent plate boundaries.
