An action or the movement of the planet on its tilted axis that involves a whole turn or circular motion from its initial point and back to it is called a rotation.
The time it takes for a planet to make a complete rotation is the length of its day.
Rotation of the planet is the circular turn or the motion of the planets on its axis from one point and back to it.
The rate of the rotation of the different planets varies based on their sizes and distances from the sun. It is also called the length of the day as the rotation defines the circular motion it completes in a defined day.
Therefore, option A is correct.

2. Other igneous rock forms from lava that cools quickly on Earth’s surface. Classify the rock as either intrusive or extrusive, and identify another word used to describe this type of rock.
3. You are studying a sample of igneous rock. The rock formed on the surface of Earth. It’s made mostly of light-colored minerals. The sample has just a few specks of dark-colored minerals. Classify the rock by type and composition.
4. You are studying a sample of igneous rock. The rock formed within Earth’s crust. The sample contains a very high concentration of dark-colored, high-density minerals. Classify the rock by type and composition.
5. A scientist shows you a sample of rock called gabbro. The scientist explains that gabbro is an intrusive mafic igneous rock. Explain what this means.
Igneous rocks that cool slowly inside the Earth's crust have coarse-grained textures. Rocks that cool quickly on the Earth's surface are called extrusive or volcanic. Extrusive rocks with primarily light-colored minerals are felsic, likely rhyolite, while intrusive rocks with dark, high-density minerals are mafic, possibly gabbro.
1. When magma cools slowly within the Earth’s crust, it gives the crystals in the forming igneous rock time to grow, creating a coarse-grained texture often visible to the nake-d eye. This is known as phaneritic texture.
2. The rock that forms from lava cooling quickly on the Earth's surface would be classified as extrusive. Another term used to describe this type of igneous rock is volcanic.
3. The rock sample described is likely an extrusive igneous rock of felsic composition, possibly a rhyolite. This type of rock is primarily composed of light-colored minerals with few dark-colored minerals present.
4. The rock described is likely an intrusive igneous rock with a mafic composition. This might be a gabbro, which typically contains a high concentration of dark-colored, high-density minerals.
5. If gabbro is classified as an intrusive mafic igneous rock, it means that it was formed by magma cooling slowly within the Earth's crust (intrusive) and it is composed primarily of dark colored, high-density minerals (mafic).

Igneous rocks are classified as intrusive or extrusive based on whether they cool slowly within Earth's crust or quickly on the surface, resulting in coarse-grained or fine-grained textures, respectively. A light-colored, surface-formed rock is likely extrusive and felsic, while a dark-colored, crust-formed rock is likely intrusive and mafic. Gabbro is an intrusive mafic igneous rock, meaning it has a coarse-grained texture and is composed of dark, dense minerals.
Igneous rocks are classified into two main types based on their formation process and resultant textures: intrusive (or plutonic) and extrusive (or volcanic).
1. When igneous rock forms from magma that cools slowly within Earth's crust, it is likely to have a coarse-grained texture due to the slow crystallization process that allows larger mineral crystals to form. This type of igneous rock is referred to as intrusive or plutonic.
2. Igneous rock that forms from lava cooling quickly on Earth's surface is classified as extrusive. This type of rock is also known as volcanic igneous rock, and it typically has a fine-grained texture due to the rapid cooling that allows only small crystals to form.
3. An igneous rock sample that formed on the surface of Earth and is composed mostly of light-colored minerals is likely an extrusive rock with a felsic composition, which means it is rich in silica. Common examples of this type include rhyolite or dacite.
4. An igneous rock that formed within Earth's crust and contains a high concentration of dark-colored, high-density minerals is likely an intrusive rock with a mafic composition, which means it is rich in magnesium and iron. This would typically correspond to a rock like gabbro.
5. Gabbro being an intrusive mafic igneous rock means that it formed within the crust from slowly cooled magma, and it is composed primarily of dark minerals like pyroxene and olivine, which are higher in density compared to the minerals that compose felsic rocks.
