Lava is pouring out of the crust at a vent on the ocean floor. As it cools, igneous rocks form.
Which characteristics would one expect to find when studying the cooled lava?
small crystals and coarse texture
small crystals and fine texture
large crystals and coarse texture
large crystals and fine texture
Answers
Answer:b. small crystals and fine texture
Explanation: Generally, igneous rocks are formed from the solidification of moltenmagma . Molten magma are usually semi liquid that originates from the interior of the earth. The location or environment where the magma solidifies determine the kind of igneous rock that is formed. If the magma solidifies below the earth crust it will result to an intrusive igneous rock which have a coarse texture due to the slow rate of solidification. But if magma creeps or erupt to the surface of the earth crust as lava, the solidification process becomes rapid to form an extrusive igneous rock.Lava pouring out of the crust at a vent or fissure on the ocean floor are more expose to cooler temperature, water and air . This result to rapid cooling and more faster crystallizing process to form more fine grain and small crystals. Example of this extrusive types of igneous rocks is Basalt. The picture below are examples of extrusive igneous rocks . Notice their small crystal .

What do we still not know about the size of the universe?
Answers
Answer: Hope this helps you!
We still don't know how much the universe extends/how big it is.
Even after many world changing discoveries about the universe, it is still unclear if the universe extends forever or not. There is no proof whether the universe ever ends, or if it is infinite. Ever since the time of the ancient Greeks, and even in the current days it is still unknown. Aristotle, a Greek astronomer developed the basic principles of the universe, and he was pretty much almost right. Even though he did this, it was only 384-322 BC, and back then along with developing the basic idea of the universe, he also inferred that the universe was infinite. Moving on to other astronomers like Aristarchus, Giovanni Cassini, Jean Richer, Heinrich Wilhelm Olbers, they all discovered something new in the field of astronomy, however, none of them, even if they inferred if space was infinite or not, nobody ever found out whether the universe had an end. Nobody was ever able to solidly support their claims whether the universe was never ending or not.

Large icebergs that travel slowly over land are known as glaciers. They are created from snow that builds up over and they may alter the appearance of the area.
What is faulting?The movement of water, nutrients, and sediments through landscapes is facilitated by river systems. When tectonic plates collide, the Earth's crust vibrates, resulting in an earthquake. Animals and plants that are living contribute significantly to the environment in which they live.
Crop rotation and cover crops are examples of practices that aid in preserving soil fertility and reducing soil erosion. The terms "faulting" and "folding" describe the tectonic forces that cause rock strata to distort, resulting in structures like mountain ranges.
When magma and ash are ejected from the Earth's crust, volcanoes are generated, and over time, they can produce new landforms. When rivers or other bodies of water overrun their banks, flooding occurs, which can harm infrastructure and force the eviction of residents.
Therefore, faulting and folding describe the tectonic forces that cause rock strata to distort, resulting in structures like mountain ranges.
