Which type of soil contains the most amount of organic matter?
circle the correct answer.
Clay Loam sandy or silt
The soil which has more organic matter is clay. Compared to clay, sandy and slit soil has very little amount of organic matter.
What is clay?Clay is a type of finely grinded soil which contains hydrous aluminosilicates such as kaolin. Clay soil contains more organic matter and it can abstract large amount of water.
Clay develop a plasticity when it is wet but can be brittle and hard when dried. Clay is a type of ceramic material widely used in making potteries. Sandy soil is made of sand particles thus rich in inorganic minerals and contains very less organic matter.
Slit soil is a type of granular soil material which have a size in between that of clay and sandy soil. Slit soil is made by sediment materials carried by water and it can form fertile deposits on valleys. Therefore, the soil type which contains more organic matter is clay.

Suppose the Moon were smaller in size but greater in mass than it is now. How would that affect solar eclipses and tides?
The tidal forces would be larger, seismic activity on the Earth would most likely be more pronounced/active.
What are tidal forces?The tidal force is a gravitational effect that stretches a body along the line towards the center of mass of another body due to a gradient in gravitational field from the other body.
Moreover, tidal forces are changes in the gravitational potential energy of the Sun, Moon and Earth. These forces cause the periodic motion of the seas which create a temporary change in water levels that vary depending on location.
Therefore, gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth.

The fossils that scientists find and study today formed thousands to millions of years ago. But, you can simulate the process of fossilization. Follow these steps to model a fossil:
1. Line the inside of the plastic container with plastic wrap.
2. Let the ends of the plastic wrap hang out of the container. The overhanging ends will allow you to more easily lift out your formation when it’s complete.
3. Pour four inches of water into the container. Use a ruler to measure the correct depth.
4. After adding the water, add two inches of sand.
5. Spread the twigs and leaves in a thin layer on the top of the sand.
Stay safe! Use gloves when handling the leaves and when checking the inside of your model during the weeks to come. Wash your hands and gloves when you are done.
Part A
After assembling the materials, record your observations. Describe what the setup looks like and the color of the leaves and twigs. Predict what changes will take place over the next few weeks.
answer below
Explanation:
it looks like a beach and the leaves are green and the twigs are brown the sticks stay the same after awhile but the leaves dry out and become brown.

Explanation: A hybrid is a offspring of parents that differ in genetically determined traits.
What are two types of evidence used to classify organisms?
Answer:
Physical and Genetic Evidence
Explanation:
Classifying organisms depends on their evolutionary histories, fossil evidence, and DNA sequences; scientists consider physical features, fossils, and DNA sequences to determine whether they are related to each other. There are three kingdoms of living things: the bacteria, the archaea, and the eukaryotes.
