The correct answer is True
Explanation:
In geography, the term "landform" refers to a natural shape or form that can be found on the surface of Earth such as mountains, hills or canyons. All of these are formed through different processes such as movement in tectonic plates. Additionally, these are considered as a physical feature of Earth as landforms define the shape and features of the Earth's surface and also influenced other physical phenomena such as weather or wind patterns. According to this, it is true landforms is a physical feature on Earth's surface.

Answer:
In order to lower the temperature.
Explanation:
Mammals and birds uses evaporative cooling due to their high body temperature because this evaporative cooling removes the high temperature from the body. In this process, the water present in the body absorb all the extra heat and remove this extra heat from the body with change its state from liquid to vapors and the body's temperature cools down. This evaporative cooling is occurs in the process of sweating.
Evaporative cooling is an evolution-driven thermal regulation method that certain organisms utilise to cool their bodies. It mainly occurs in organisms living in hot environments like kangaroos.
Evaporative cooling is a biological process related to evolution and is used as a thermal regulatory method by certain organisms. Evaporative cooling occurs when an organism excretes water from its body surface, which then evaporates, absorbing heat and subsequently leading to cooling. This evolutionary adaptation generally occurs in organisms that live in warm or hot environments where they are exposed to high temperatures. An example of an organism using evaporative cooling is the kangaroo, which licks its forearms, allowing the saliva to evaporate and cool its body during intense heat.

Answer:
Excessive consumption is understood as an uncritical purchase. Thus, people who buy compulsively do not analyze the social and personal consequences of the purchase.
Explanation:
The warning about the risks of overpopulation has been the subject of books and discussions for many decades. Today the imbalance caused by overconsumption generates international debates, conferences, targets for reducing greenhouse gases, water consumption, installation of clean energy, among other internationally announced commitments.
This is because excessive consumption is made at the expense of natural resources. The more industrialized products are manufactured, the more natural resources are consumed. The more we buy these products, the more they are manufactured.
In view of the improvement in the quality of life and the higher gains, the population consumes a lot and directly interferes in the extraction of resources. In the consumption level data between rich and poor countries, the disparity in which the former vastly outweighs the latter is clear. Not to mention that rich countries encourage the extraction of resources in underdeveloped countries to meet their needs, since their resources have been depleted for a long time.
Imagine you want to conduct an experiment to understand how just one of these variables differs in a local lake, depending on its depth. This lake reaches a depth of 17 meters. For this activity:
Pick a variable that might change as you go deeper in the lake on a given day.
Do a little research on that variable to determine how you might measure it in a lake.
Use the template below to outline an experiment to investigate this variable in the lake by depth. For each part, simply answer the question in parentheses to create your outline.
Type your response to each field in the space below that field:

Complete question:
Fish are sensitive to many environmental variables: dissolved oxygen, light, temperature, pH, clarity of the water, food supply, presence of predators, etc. Fish will be attracted to different locations in a lake, based on its mix of variables.

Answer and Explanation:
Variable: dissolved oxygen
Title:Oxygen variation as a water quality indicator.
Purpose: To study how dissolved oxygen varies with depth
Hypothesis: The percentage of dissolved oxygen will decrease as depth increases.
Procedure/Method:
Observations:
%DO in each site and depth will be recorded in order to analyze how it varies with depth.
Data analysis:
According to different indicators of water quality in a lake, the observed %DO will be compared and analyzed to evaluate the sanity state of the lake water. Example of valuation scale,
NORMAL index: Oxygen concentration in the water column is found to be sufficient for the fish survival
REGULAR: Decrease in oxygen concentration at greater depth, values below saturation in the background
CRITICAL: Null oxygen concentration in all or part of the column profile of water. Probable fish mortality events.
According to the taken data, observations on the study site will be taken, such as the variation in oxygen concentration as it gets deeper, until reaching hypoxia level, where fishes can not survive. Data can be presented in tables and in graphs, in both cases comparing sampling sites and depth, making a focus on the valuation scale.
Conclusion:
Association of the oxygen variation with the sanity state of the lake, microbiology decomposition processes at different depths, eutrophication state, among others.
