Anearthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault.
or
An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves.
Earthquakes are accordingly measured with a seismometer, commonly known as a seismograph.
The magnitude of an earthquake is conventionally reported using the Richter scale or a related Moment scale
An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground.
The strain becomes so great that rocks give way by breaking and sliding along fault planes.
Earthquakes may occur naturally or as a result of human activities.
Smaller earthquakes can also be caused by volcanic activity, landslides, mine blasts, and nuclear experiments.

Spores are produced by plants, bacteria, and fungi, but the zygote, the embryo, and the blastula are all stages in the development of the human body.
Human reproduction starts with the joining of two haploid sex cells, the egg, and the sperm cells. When those two fuse in the process of fertilization, they form the zygote which is the one cell that is the basis of the human development.
After the fertilization, the zygote starts to divide, making two cells, those two cells divide again making four cells and so on. Those cells start to stick to each other and form layers, which is called the blastula stage.
With further divisions of the cells and layer development the cells of the blastula, called blastocysts eventually form the embryo.
The embryo has three distinct layers, the ectoderm (which later develops into skin and the nervous system ), the mesoderm ( which later develops into muscles and blood cells) and the endoderm (which later develops into internal organs).
