In the United States, the moon’s pull is strongest during which season?
1. spring
2. summer
3. fall
4. winter
Answers
Explanation:
Gravitational pull is affected by mass and distance. Since the moon’s mass does not change, the moon’s distance between Earth and the moon is the main consideration for the strength of lunar gravity. The moon’s pull on Earth waxes and wanes as the moon follows its elliptical orbit around the Earth, the distance between the two celestial objects increases and decreases. When they are nearest to each other, the moon is in the point of its orbit called the perigee, and its pull on Earth is the strongest.
On Earth, the moon’s gravity primarily is manifested as high and low tides, as the water bulges toward the moon. The effects of lunar gravity are felt the most at the constantly changing spot on Earth that is directly beneath the moon, called the sub-lunar point. At most times of the year, the moon has a greater pull on Earth than the sun does, but this changes during the times of year when the Earth’s orbit brings it closer to the sun. At these times, the sun’s gravitational pull causes spring tides, and when these coincide with the moon’s orbital perigee around the Earth, they are called perigean spring tides.
Earth exerts a gravitational pull on the moon 80 times stronger than the moon’s pull on the Earth. Over a very long time, the moon’s rotations created fiction with the Earth’s tugging back, until the moon’s orbit and rotational locked with Earth. This is called "tidal locking," and it explains why the same side of the moon always faces the Earth.
Answer: The correct answer is 1. spring

Answer:

Your answer is CLEAR CUTTING...
Explanation:
Clear cutting is when people/ industries harvest and regenerate trees areas in which all trees are cleared from a site completely...
HOPE THIS HELPS!!
Clear cutting can cause secondary succession. So, the correct option is A.
What is Secondary succession?When a place is disturbed but not severely enough to completely clear it of all vegetation and soil, secondary succession happens. Secondary succession can be started by a variety of disturbances, including fire, flooding, high winds, and human activities (such as logging of forests).
After the primary succession has indeed been disrupted as well as some animals and plants are still there, the secondary succession occurs. For the reasons listed below, the secondary succession is typically quicker than the primary succession.
There is already earth in place.The soil may still contain seeds, roots, and subsurface vegetative organs.Therefore, the correct option is A.

It was Charles Darwin who called the birds seen on the Galapagos islands as the finches. These birds show a remarkable diversification in their beak based on their chief food.
What are Darwin's Finches?Charles Darwin observed a group of small sparrow like black birds with strong, short beaks which are known today as Darwin's finches. These finches varied on different islands, but they were closely related to one another.
These finches evolved from a common ancestors to have different beaks well suited for different types of food they feed on. Generally long and pointed beaks are suitable for seed and cactus feeders. Even some short beaked finches tear up the base of the cactus and feed on its pulp.
The slender and sharp beaks are common in insect eating finches. The process by which they successfully evolved and radiated to different habitats is called the adaptive radiation.

I think that the amount of water vapor in the air will be different because in Mark's town, it is cold and water in the clouds might turn to ice and come down as snow. And in Vikki's town, it is very warm so the water vapor might come down as rain.

How does energy affect competition in a rainforest?
Answers
Answer:
Energy affects competition in the tropical rainforest due to the dense population of trees found in this region.
Trees are producers and they compete mainly for water, sunlight and nutrients. Sunlight provides the source of solar energy which is instrumental in its photosynthetic process.
The trees form canopies and create competition among the ones who have lower stems and branches while the ones with longer stems continue to grow taller due to the availability of sunlight.
Competition may also affect the organisms living in this region as they compete for food.
