5 0

Answer:

100 extinctions per million species per year

Explanation:

  • The background extinction also knows as the standard rate of extinction in earth geology and biological history and these rates are used for the comparison and from the estimate rats of the species diversification and specialization of species the estimates are 100 or 1000 times higher than normal extinction.

Identify three (3) different ocean-ocean convergent boundaries. Be sure to indicate which two plates are involved in the collisi
Nadya [2.5K]

Answer:

i south American plate(Note that the south american plate has both oceanic and continental plates) convergence with the Caribbean plate

ii Pacific plate converging with the North American plate

iii Pacific and the Mariana plates

Explanation:

Convergent boundaries are boundaries where tectonic plates collides. The plate collision might be between oceanic plate and continental plate, continental and continental plate and oceanic and oceanic plates. Usually, when the continental plate collides with the oceanic plates the more denser plate which is the oceanic plate subduct.

Ocean-ocean convergent boundaries is the collision between oceanic plates.Three different occurrence of ocean-ocean convergence are  

i south American plate(Note that the south american plate has both oceanic and continental plates) convergence with the Caribbean plate. The more denser plate subduct after the collision which is the south American plate. The south American plate is more cooler and denser than the Caribbean plate so it will descend beneath the  Caribbean plate.

ii Pacific plate converging with the North American plate(oceanic plate section). The pacific plate will descend  beneath North American plate because of it denser nature.

iii Pacific and the Mariana plates. The pacific will also be subducted here because Mariana plate is less dense than it  and even more buoyant .

The general geologic features/phenomenon found in this kind of boundaries are trenches , Island arc, volcanoes, earthquakes etc

calculate the amount of energy required to convert 100g of ice at 0.00 degrees Celsius to water at 0.00 degrees Celsius
garik1379 [7]

Answer:

33300J

Explanation:

Given parameters:

Mass of ice  = 100g = 0.1kg

Initial Temperature of water  = 0°C

Final temperature  = 0°C

Unknown:

Amount of energy = ?

Solution:

The amount of energy is given by;

  Amount of energy =  mL

m is the mass

L is the latent heat of fusion  = 3.33 x 10⁵ J/kg

   Amount of energy = 0.1kg x 3.33 x 10⁵J/kg

  Amount of energy  = 33300J
