Answers

Answer 1

Answer:

Explanation:

true

Answer 2

Answer:

True

Explanation:

In Earth’s history before the Industrial Revolution, Earth’s climate changed due to natural causes not related to human activity. Most often, global climate has changed because of variations in sunlight. Tiny wobbles in Earth’s orbit altered when and where sunlight falls on Earth’s surface.

The diagram below shows a model of the greenhouse effect... Which would happen MORE if there were NO GREENHOUSE GASSES in the atmosphere at all? *

Process A (Infrared heat escaping into space)
Process B (Sun sending light energy to Earth)
Process C (Infrared heat being trapped in the atmosphere)
None of those processes would change if there were no greenhouse gasses.

Answers

Process A.

this is because the diagram shows that the infrared light returns into space. all of the other options are affected by the greenhouse gas layer, as the infrared rays bounce back onto earth. the greenhouse gases are very harmful to the earth because they cause all of those infrared heat rays to earth and they get trapped in the atmosphere because the greenhouse gases block them from escaping.

Process A (Infrared heat escaping into space) would happen MORE if there were no greenhouse gases in the atmosphere at all.

What is green house gases?

Greenhouse gases, such as carbon dioxide, methane, and water vapor, are present in the Earth's atmosphere and help to trap some of the heat that is radiated from the Earth's surface. This is known as the greenhouse effect. Without these gases, more of the infrared heat that is radiated from the Earth's surface would escape into space, causing the Earth to be colder.

Process B (Sun sending light energy to Earth) and Process C (Infrared heat being trapped in the atmosphere) would not be affected by the presence or absence of greenhouse gases.

How can plants help to decrease the amount of carbon dioxide in the atmosphere?

Answers

Answer:

As plants and trees develop, they take carbon dioxide from the atmosphere and turn it into sugars through photosynthesis. Moreover, planting extra trees could remove more carbon from the atmosphere and store it for a long time.

or

Plants and trees absorb carbon dioxide from the atmosphere and convert it to sugars through photosynthesis as they grow. Furthermore, by planting more trees, more carbon will be extracted from the atmosphere and deposited for a long time.

(both are the same they are just worded differently, pick which one you like best)

Plants consume the carbon that humans and other animals breath out as they produce oxygen that we breath in, so it is a sort of symbiotic relationship between humans and plants.

Describe the steps of the rock cycle and relate them to weathering, erosion, plate tectonics, and mountain building

Answers

Answer:

The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.

Explanation:

The Rock cycle is the geological concept, in which transitions between sedimentary, metamorphic, and igneous rocks over geologic time occurs. The transitions between rocks occur due to weathering, metamorphism, erosion, and sedimentation.

The steps involved in the rock cycle are:

Weathering refers to the breakdown or dissolving of the rocks on the Earth's surface.

After the weathering, the process of erosion occurs in which rock particles and minerals are transported via plants, animals, wind, and water.

The igneous rocks are formed by plate tectonics. The heat from the mantle fuels the plate tectonics, which converts the igneous and sedimentary rocks into metamorphic rocks.

Mountain building is caused by the intense deformation of layered rocks and the activity of metamorphic and igneous rocks in the orogenic stage.

Thus, the rock cycle is involved in various processes and transitions among different types of rocks that occur in the rock cycle.

Explain the relationship between the variation in estradiol and progesterone rates in the female body and the events that occur in the uterus during the menstrual cycle

Answers

Answer:

The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces progesterone. During most of this phase, the estrogen level is high. Progesterone and estrogen cause the lining of the uterus to thicken more, to prepare for possible fertilization.

Progesterone and estrogen are necessary to prepare the uterus for menstruation, and their release is triggered by the hypothalamus. Once you reach puberty, the ovaries release a single egg each month (the ovaries typically alternate releasing an egg)—this is called ovulation.
