Answer:
Mid-ocean ridges are geologically important because they occur along the kind of plate boundary where new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a "spreading center" or a "divergent plate boundary." The plates spread apart at rates of 1 cm to 20 cm per year.Explanation:

Answer:
answer is C. 10 g
Explanation:
: When an object floats, it displaces an amount of water that has the same mass as itself. Therefore, the mass of the water in the graduated cylinder is equal to the mass of the object. We can see that there are 10 mL of water in the graduated cylinder. We also know that the density of water is 1 g/mL. Since each mL of water has a mass of 1 g, then 10 mL of water has a mass of 10 g. If the mass of the displaced water is 10 g, then the mass of the floating object is also 10 g.
Answer:
6 x 10³ [m]
Explanation:
La notación científica corresponde a multiplicar el primer numero por una base de 10 elevada a la potencia requerida, esa potencia se determina por la cantidad de ceros después del numero. Para el ejercicio.
6000 [m] = 6 x 10³ [m]
Elevado a la tres, ya que se tienen 3 ceros después del numero seis.
Otro ejemplo seria 25000; 25 x 10³
Mas ejemplos:
3645 = 3.645 x 10³ (tres números a la derecha después del primer numero)
550000 = 550 x 10³, también es igual a 55 x 10⁴.
<u>Answer
</u>
D. Salt water is denser than freshwater.
<u>Explanation</u>
A boat is able to float on water because it experiences an upthrust upwards.
The magnitude of the upthrust depends on the density of the liquid.
When the liquid is denser the boat will experience a great upthrust as compared to when in a less dense liquid.
If the boat sinks lower in the freshwater than in salty water, then Salt water is more dense than freshwater.
