Problem: What is the missing first step of the following process: - Slide out the bottom rack - Take a dirty plate - Rinse the plate - Place the dish in the rack - Repeat leaving enough space for water to reach all items - Fill the soap cup - Turn on the dishwasher.

A: Open the Dishwasher

Problem: What is the missing first step of the following process: - The fault lines grow over time - The rocks on each side of the fault lines rub against the rocks on the other side of the fault line - The rocks put pressure on each other - The rocks break from the pressure - The breaking of the rocks releases a lot of energy - The energy causes seismic waves - The seismic waves make the earth shake.

A: Fault lines appear underground

Problem: What is the missing first step of the following process: - Heating element heats water - Pump forces water up in pipes connected to spinning paddles - The forced water makes paddles spin like a sprinkler - Water comes out of small holes in paddles - Water is collected and used again until dishes are clean - Water is drained through a filter - Filter collects particles of food - Water was so hot that it evaporates for dry dishes.

A: Cold water taken in through a hose to the bottom

Problem: What is the missing first step of the following process: - Magma rises - Collects inside magma chambers underneath a volcano - Pressure builds in the magma chambers as they fill - Gain energy for eruption - Some of the energy is converted into seismic activity (earthquakes) - If the magma building in the volcano is thick and sticky it will trap gases - Results in an explosive eruption when the pressure becomes too intense - If the magma is thin and runs - The magma results in a low-pressure, slow-moving flow of magma instead of a violent eruption -

A:
Magma is formed when rock melts inside the Earth's crust
