Ok ok no fret im here to help as best as i can :)
Weathering is a process that breaks down or changes rocks into smaller pieces. Various atmospheric aspects are responsible for weathering processes. Weathering is different from erosion. Erosion is the movement of rock pieces and sediment from one area to another. Weathering is the breaking down of rocks and erosion is a wearing away of rocks. There are two main types of weathering: physical (or mechanical) weathering and chemical weathering. Quite often, both forms of weathering will occur together

Physical weathering is also known as mechanical weathering. This type of weathering occurs when rocks and other landforms are broken down by physical factors in the environment. These physical factors include wind, water, sun, ice and temperature changes

What role does transpiration play in the water cycle
Airida [17]

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. Transpiration also includes a process called guttation, which is the loss of water in liquid form from the uninjured leaf or stem of the plant, principally through water stomata.

Studies have revealed that about 10 percent of the moisture found in the atmosphere is released by plants through transpiration. The remaining 90 percent is mainly supplied by evaporation from oceans, seas, and other bodies of water (lakes, rivers, streams).

Transpiration and plant leaves

Plants put down roots into the soil to draw water and nutrients up into the stems and leaves. Some of this water is returned to the air by transpiration (when combined with evaporation, the total process is known as evapotranspiration). Transpiration rates vary widely depending on weather conditions, such as temperature, humidity, sunlight availability and intensity, precipitation, soil type and saturation, wind, land slope, and water use and diversion by people. During dry periods, transpiration can contribute to the loss of moisture in the upper soil zone, which can have an effect on vegetation and food-crop fields.

At the coordinates 45 degrees W & 72 degrees N it is 9:32 AM. What time is it at the coordinates 75 degrees W & 45 degre
garik1379 [7]

Answer:

The correct option is;

7:32 AM

Explanation:

The information given are;

The time at 45 degrees W and 72 degrees N = 9:32 AM

The variation of time with lines of longitude  is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west  of the initial location

Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted

The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM

The latitude of a place left out in the calculation of the relative time of a place.

Which level of consumer has access to the smallest supply of energy?
Klio2033 [76]
The shorter the food chain, the larger amount of energy obtained. 
Hence, the consumer furthest away from the producer obtains the least energy. 
The quaternary consumer is furthest away. Most energy is lost by then. Hence, it has access to the smallest supply of energy.

There have been many reports of environmental improvements being seen around the world due to self isolation orders. What do you
kaheart [24]
Though the lockdown has undoubtedly had somewhat of a negative impact on certain acpects of our society, there’s no denying that our environment has seen certain benefits since we’ve tucked ourselves away in our homes. According to the Earth Observatory at NASA, satellites have detected decreased levels of air pollution as well as carbon monoxide emission. This is attributed to the closure of most industries as well as the lack of cars and other transportation on the road. Though it isn’t just the air we’re beginning to notice changes in- for the first time in a very long time, the canals in Venice are crystal clear. With fewer boats and tourists about, the water is free of pollution for the first time in centuries. With these facts in mind, I can safely say that I believe the lockdown has definitely positively benefited the environment, but it’s up to us to keep it that way once it ends.
