Highwall mining is often used when excavating an open-pit mine becomes too expensive. There are many advantages over underground mining, including the fact that it is both more cost-effective and involves less lead time.

Trench warfare faced challenges<br> including sanitation, injury and mud.<br><br> True<br> False
Aneli [31]
True. If you are in a trench, you are literally sitting in a hole in the dirt for hours on end; sometimes keeping watch, sometimes in the heat of battle. If you get injured, there are tons of diseases in the dirt and from humans just sitting in that hole for large amounts of time, usually without showering for days or weeks (depending on where you are and the resources available). Injury, you could get shot in the shoulder while firing, or someone could throw an active grenade into the trench and, well, it wouldn't end well. Mud-- you're sitting in a hole, in the dirt. If it rains, you are now sitting in a wet hole in the dirt, and dedication to your country--or flying bullets--is keeping you there.

Which of the following can plate tectonics help explain? (Select all that apply.)
BaLLatris [955]

Answer:

- the distribution of earthquakes

- certain fossil distributions

- the distribution of volcanoes

- the location of mountain chains

Explanation:

The plate tectonics are crucial for the processes that happen on the surface or near it on our planet, as well as the physical features of it. The movement of the tectonic plates causes lot of stress when they interact, and from that stress, the crust deep inside cracks and adjusts, which releases a lot of energy and causes earthquakes. Also, on the plate boundaries, because the crust is cracking and is not as tough, the magma from the mantle manages to rise up, and as it reaches the surface it lifts up the land in a cone shape, creating volcanoes, be it as island or continental arcs. When continental tectonic plates collide, they don't subduct, but push against each other, and that enormous pressure lifts up the area around the boundary, gradually giving rise to mountain chains. The fossils are n interesting example as well, as they are one of the best clues about the movement of the tectonic plates. There are lot of fossils that are identical, from the same species, but found on different continents that are not connected in the present, indicating that in the past the continents had different positions and were connected.

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
