There are three types of rocks on Earth. Each rock type forms in a different way. Igneous rocks were the first rocks on Earth. They form from molten rock. Molten rock is rock that has turned to liquid because of extreme heat. Lava is the name for the molten rock that erupts from volcanoes. When molten rock is below the Earth’s surface, it’s called magma. When molten rock—either lava or magma—cools, it hardens into a solid. This forms igneous rocks. Some examples of igneous rocks are granite, obsidian and basalt. Much of Hawaii’s coast is covered in basalt. Waves break the basalt down over time, creating the black sand of some Hawaiian beaches.
Which of the following is true about lava and magma?
A. Lava and magma are both types of molten rock.
B. Magma uses waves to break down lava over time.
C. When magma cools and hardens it becomes lava.
D. Magma is called lava when it’s below the Earth’s surface.
Answers
Lava is example of molten/ liquid rock
So is magma
The only difference is that magma is not lava until it comes out of the volcano

What is Dessert ?Dessert is the final course of a meal. The dish includes sweet snacks like sweets and sometimes a beverage like dessert wine or liqueur. There is no tradition of a dessert course to finish a dinner in several regions of the world, such as Greece and West Africa, and in most parts of China.
Desserts include biscuits, cakes, cookies, custards, gelatins, ice creams, pastries, pies, puddings, macaroons, sweet soups, tarts, and fruit salad. Fruit is also typically seen in dessert courses due to its inherent sweetness. Desserts are made in certain cultures by sweetening savoury dishes. In the 18th and 19th centuries, when refined sugar and wheat were widely available and ostentation and artifice were desired, the dessert course achieved its pinnacle in the feasts of the European courts. Numerous creams, tarts, fruits, cakes, pastries, puddings, jellies, and meringues were given on tables decorated with flowers and architectural fancies made of sugar and pastry.
Hence option B is correct.

Read this excerpt from Through the Looking-Glass by Lewis Carroll.
She was rambling on in this way when she reached the wood: it looked very cool and shady. “Well, at any rate, it's a great comfort,” she said as she stepped under the trees, “after being so hot, to get into the—into WHAT?” she went on, rather surprised at not being able to think of the word. “I mean to get under the—under the—under THIS, you know!” putting her hand on the trunk of the tree. “What DOES it call itself, I wonder? I do believe it's got no name—why to be sure it hasn't!”
She stood silent for a minute, thinking: then she suddenly began again. “Then it really HAS happened, after all! And now, who am I? I WILL remember if I can! I'm determined to do it!” But being determined didn't help much, and all she could say, after a great deal of puzzling, was, “L, I KNOW it begins with L!”

You can take your heart rate using:
Question 4 options:
Radial Pulse Point
Carotid Point
None of the above
A and B
Answers
Answer:
A I think
Explanation:
at the wrist lightly press the index and the middle fingers of one hand on the opposite wrist just below the base of the thumb at the neck lightly press the side of the neck just below the jawbone count the number of beats in 15 seconds and multiply by four and that's your heart rate
You can take your heart rate using both the Radial Pulse Point and the Carotid Point. The correct answer is "A and B."
1. Radial Pulse Point: The radial pulse is taken by placing two fingers (usually the index and middle fingers) on the radial artery, which is located on the wrist, on the same side as the thumb. By feeling the pulsations, you can count the number of beats per minute, which gives you the heart rate.
2. Carotid Point: The carotid pulse is taken by placing two fingers (usually the index and middle fingers) on the carotid artery, which is located on either side of the neck, just below the jawline. Again, you can count the number of beats per minute to determine the heart rate.
Both methods are commonly used to measure heart rate, and they are easy to access and provide accurate results. However, it's essential to be gentle when taking a pulse to avoid putting excessive pressure on the arteries.

Describe the 3 layers of the mantle
Answers
Answer:
The 3 main layers are the core, mantle and crust
Explanation:
Answer:
I hope this is the answer for your question
Explanation:
Mantle is the widest section of the Earth. Its thickness is approximately 2,900 km. The mantle is mainly made up of semi-molten rock known as magma. The rock is hard in the upper part of the mantle, but lower down the rock is softer and begins to melt.
The mantle is located directly under the Sima. The mantle consists of very hot and dense rock. This layer of rock flows like asphalt under heavy weight. This flow is because of the greatest temperature differences from the bottom to the top of the mantle. The reason behind the plates of the Earth move is the movement of the mantle. Its temperature varies between 1600 oF at the upper part to 4000 oF near the bottom.

List three evidences that show that the Bible is the Word of God.
Answers
Answer:1.God tells us that He is the Author (2 Peter 1:20-21 Open in Logos Bible Software (if available) & 2 Timothy 3:15-17 Open in Logos Bible Software (if available))
1.The Old Testament and New Testament Authors understood they were writing the Word of God. Common Old Testament phrase – “Thus saith the Lord”. The Apostle Peter confirmed the Apostle Paul’s writings as Scripture (2 Peter 3:16)
3.Its Historical Accuracy – as verified by archeology, which has never contradicted the Bible, but only confirms and silences its critics.
Explanation:
Answer:
Many people question who the author of the Bible is and wonder if the Bible is really the Word of God. I want to give you five reasons to affirm that the Bible is God's Word.
The Word of God: Evidence that Scripture is Divine
First, I believe the Bible is the Word of God because of its scientific accuracy. The Truth of the Word of God tells us that God “hangeth the earth upon nothing” (Job 26:7). How did Job know that the earth hung in space before the age of modern astronomy and space travel? The Holy Spirit told him. The scientists of Isaiah’s day didn’t know the topography of the earth, but Isaiah said, “It is [God] that sitteth upon the circle of the earth” (Isaiah 40:22). The word for “circle” here means a globe or sphere. How did Isaiah know that God says upon the circle of the earth? By divine inspiration.
Secondly, the Bible is affirmed through historical accuracy. Do you remember the story about the handwriting on the wall that is found in the fifth chapter of Daniel? Belshazzar hosted a feast with a thousand of his lords and ladies. Suddenly, a gruesome hand appeared out of nowhere and began to write on a wall. The king was disturbed and asked for someone to interpret the writing. Daniel was found and gave the interpretation. After the interpretation, “Then commanded Belshazzar, and they clothed Daniel with scarlet, and put a chain of gold about his neck, and made a proclamation concerning him, that he should be the third ruler in the kingdom.” (Daniel 5:29). Basing their opinion on Babylonian records, the historians claim this never happened. According to the records, the last king of Babylon was not Belshazzar, but a man named Nabonidas. And so, they said, the Bible is in error. There wasn’t a record of a king named Belshazzar. Well, the spades of archeologists continued to do their work. In 1853, an inscription was found on a cornerstone of a temple built by Nabonidas, to the god Ur, which read: “May I, Nabonidas, king of Babylon, not sin against thee. And may reverence for thee dwell in the heart of Belshazzar, my first-born favorite son.” From other inscriptions, it was learned that Belshazzar and Nabonidas were co-regents. Nabonidas traveled while Belshazzar stayed home to run the kingdom. Now that we know that Belshazzar and Nabonidas were co-regents, it makes sense that Belshazzar would say that Daniel would be the third ruler. What a marvelous nugget of truth tucked away in the Word of God!

Answers
The x and y component of the drone vector are 21.21 mph and 21.21 mph respectively.
The x and y component of the wind vector are -7.5 mph and -12.99 mph respectively.
The total x-component of the combined Drone + Wind vectors is 13.71 mph.
The total y-component of the combined Drone + Wind vectors is 8.22 mph.
The magnitude of the total vector is 15.99 mph.
The total angle of the combined Drone + Wind vectors is 31⁰.
What is the x and y component of the drone vector?The x and y component of the drone vector is calculated as follows;
Vx = 30 mph x cos (45)
Vx = 21.21 mph
Vy = 30 mph x sin (45)
Vy = 21.21 mph
The x and y component of the wind vector is calculated as follows;
θ = 240⁰ - 180⁰ = 60⁰
Vx = -15 mph x cos (60)
Vx = -7.5 mph
Vy = -15 mph x sin (60)
Vy = -12.99 mph
The total x-component of the combined Drone + Wind vectors is calculated as;
Vx_tot = 21.21 mph -7.5 mph = 13.71 mph
The total y-component of the combined Drone + Wind vectors is calculated as;
Vy_tot = 21.21 mph - 12.99 mph = 8.22 mph
The magnitude of the total vector is calculated as;
V = √ (13.71² + 8.22²)
V = 15.99 mph
The direction of the combined vector is calculated as;
θ = tan⁻¹ (Vy_tot/Vx_tot)
θ = tan⁻¹ (8.22/13.71)
