Define sedimentary rock.(1 point) Sedimentary rock is a type of rock that is formed over long periods of time by the transformation of existing rock types. The original rock is subjected to large heats and pressures causing very large changes.

Sedimentary rock is a type of rock formed over long periods of time by the cooling and solidification of molten Earth material.

Sedimentary rock is a type of rock that is formed in a very short period of time by sudden violent volcanic eruptions into the ocean. The hot molten material becomes rock very quickly in the cool water.

Sedimentary rock is a type of rock that is formed over long periods of time by layers of silt building up on the floor of a body of water, which is then subjected to the immense weight of the ocean above it.

Step-by-step explanation:

ok I think the answer is the second one

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
