The Earth's rocks fall into three categories based on how they're formed. Which of the following is formed from the hardening of molten rock?
marble |
|
sedimentary |
|
igneous |
|
metamorphic |
The Earth's rocks fall into three categories based on how they're formed. Igneous rock (granite, basalt, obsidian) is formed from the hardening of molten rock (lava), sedimentary rock (shale, sandstone, coal) is formed by the gradual despositing and cementing of rock and other debris, and metamorphic rock (marble, slate, quartzite) which is formed when existing rock is altered though pressure, temperature, or chemical processes.

In cell biology, what part of the cell contains organelles?
cell wall |
|
nucleus |
|
cytoplasm |
|
cell membrane |
The nucleus of a eukaryotic cell contains the genetic material of the cell and is surrounded by cytoplasm which contains many organelles.
Which is the proper order of Earth's atmospheric layers from the surface up to space?
stratosphere, troposphere, mesosphere, thermosphere |
|
troposphere, stratosphere, mesosphere, thermosphere |
|
mesosphere, thermosphere, stratosphere, troposphere |
|
thermosphere, mesosphere, stratosphere, troposphere |
The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.
