Two processes are described below:

Process A: Rapid moving water strikes a rock on the bottom of a stream and breaks it into pieces
Process B: Glaciers moving along a rocky surface form cracks in the rocks

Which statement is true about the processes?

Both represent physical weathering.
Both represent chemical weathering.
Process A is physical weathering and Process B is chemical weathering.
Process A is chemical weathering and Process B is physical weathering.

Answer:

They both represent physical weathering.

Explanation:

There is no chemical process that takes place in either process.

⇒Both represents physical weathering

An important step in science is supporting a theory or idea with data. The questions we ask help determine the type of data we collect.In the warm up, you reviewed the equation to calculate kinetic energy. What question could you ask about kinetic energy which will include the variables that affect it?

As a result of natural occurrences and human activities, the Earth is constantly changing. In order to survive in this changing environment, organisms must adapt so they can continue to acquire and use resources, grow, reproduce, and
A.
restore the Earth to its original condition.

maintain stable conditions in their bodies.

A class is learning about the evaporation step in the water cycle using a simple model. The model consists of a 1-L container of water. When the container is open, and it receives sunlight, the water can freely evaporate from the container. The students design an experiment using the model. In the experiment, the container will be filled and left open outside from dawn until dusk at different times of the year. The students will run the experiment only on days with clear weather. As a basis of their experiment, the students make an assumption that more water will evaporate from their model when more solar energy is present. Which of the following is a result that the students could predict in order to test their assumption?
A.
Equal amounts of the water will evaporate on summer days and winter days.
B.
Less of the water will remain in the container after one day in summer than after one day in winter.
C.
Less of the water will remain in the container after one day in winter than after one day in summer.
D.
Some of the water will evaporate on winter days but not on summer days.

Which statement names and best describes the process in the diagram?
A) Meiosis; occurs during asexual reproduction and will not result in genetic variation among the offspring.
B) Meiosis; occurs before sexual reproduction and will result in offspring with different genetic information from the parent.
C) Mitosis; occurs during asexual reproduction and will not result in offspring with different genetic information from the parent.
D) Mitosis; occurs before sexual reproduction and will result in genetic variation among the offspring.

Seed Germination Investigation
 The students are to investigate the process of seed germination during their summer
vacation.
 They will select different types of seeds, such as beans, peas, or sunflower seeds.
 Encourage students to set up a germination experiment by placing the seeds in
different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to
pot the same seed in more than one pots.
 They should observe and document the changes that occur over time, including the
emergence of roots and shoots
