A hole in the ground that opens up suddenly is often referred to as a sinkhole. Sinkholes can form due to the erosion of underground limestone, which creates voids that eventually collapse, leading to a sudden depression or hole at the surface. These geological features can be dangerous, as they can occur without warning and may swallow structures or vehicles. They are more common in areas with karst topography, where water has eroded the rock over time.
When a>0, the function opens up. When a<0, the function opens down.
To determine if a parabola opens up or down, look at the coefficient of the quadratic term in its equation, typically in the form (y = ax^2 + bx + c). If the coefficient (a) is positive, the parabola opens upwards; if (a) is negative, it opens downwards. You can also visualize the vertex: if the vertex is the lowest point, it opens up, and if it's the highest point, it opens down.
The equation that describes a parabola that opens up or down with its vertex at the point (h, v) is given by the vertex form of a quadratic equation: ( y = a(x - h)^2 + v ), where ( a ) determines the direction and width of the parabola. If ( a > 0 ), the parabola opens upwards, while if ( a < 0 ), it opens downwards.
If a is positive, then the parabola opens upwards; if negative, then it opens downwards.

The remaining child will suddenly drop to the ground.
Edna St Vicent Millay's 'Renascence'
He meant that he had fell back onto the ground because he fainted.
To break the ground you need to jump up where all the switches are and click on them. then you drag them all down and press the green button. Suddenly the ground breaks!
Yes, it is still up but it looks like a whole in the ground.
it is sucked up into a whole then its shot up like a volcano
Please be careful when crossing the stream. A stream of light suddenly lit up the whole room.
When hindus worship, the sky opens up and stars start falling on to the ground and this lights- up the entire earth. Amazing right?? :) Not really
earthquakes
probably. my guess is that ginger root is the whole thing, and ground ginger would be chopped up/finely ground ginger root.
Sprout would be a word for 'to shoot up suddenly'.
